Dads’ & Childrens’ Fishing Trip

I’ve been talking about the idea of going fishing for some time now. I’ve never done it before and I like the idea of catching fish to eat. My son has been watching “Hugh’s Fish Fight” and was also very keen. As it happens a friend who lives locally is quite into fishing and having discussed it with him he very kindly offered to organise a trip, inviting a few others along as well.

So it was that at stupid o’clock last Sunday morning we boarded the Scooby Doo Too at Watchet Marina; four dads, six children and very little fishing experience between us. We were on a four-hour trip, two hours either side of high tide. The skipper and his crew were excellent, very helpful and seemed genuinely pleased to have so many young children interested in fishing on board.

We were taken out a short distance from the Marina so we’d still be relatively sheltered from the wind as it was a little choppy and the skipper was mindful of having so many first-timers on board. We anchored at a location with mud on the sea floor about ten metres deep and after a bit of explanation about using the rods, the hooks were baited up and dropped over the side with much anticipation. Fishing off the bottom like this were were told to expect some rays and conger eels amongst the catch.

In terms of landing edible fish I’m afraid to say we didn’t do that well. Whilst almost everyone landed a fish of some sort, we spent a fair while wrangling with quite a few conger eels (at least one of which was bigger than the child on the other end of the rod), caught some juvenile thornback rays and three or four small dogfish, but the only genuinely edible fish we ended up taking back were three whiting (one of which I caught, which was pleasing). Surprise of the morning was a whiting that was caught with a conger attached. The eel wasn’t on the hook, cut certainly wasn’t keen to let go of its breakfast either…

On our return to the harbour we dropped our gear and catch off at the cars and dropped into the nearest hostelry for a drink and some crisps and to introduce the children to their first games of pool and darts.

Despite the painfully early start I have to say it was a very pleasurable morning and I’m really looking forward to going again. Could be that we do a dads-only trip so we can get a bit more adventurous and stay out for longer, and save the next trip with the children until late Spring/early Summer and see if we can find ourselves some mackerel. In the meantime I guess I should try to find out a bit more about what I’m doing…

MythTV Freeview Channel Scan

Despite a few rearrangements of the channels on our local transmitter I’ve been putting off rescanning the channels for some time as last time I tried it broke things horribly. Nothing was due to record for a few hours yesterday evening though, so I screwed my courage to the sticking place and waded in.

First step was up upgrade all the XMLTV stuff on the backend. I took a backup copy of /usr/share/xmltv/tv_grab_uk_rt/channel_ids before starting so I could get some idea of what had changed. I’m running a CentOS5 box for the backend, so the upgrade was just a case of:

yum update '*xmltv*'

The differences between the two channel_ids files were enormous, so at this point I was starting to get apprehensive. To update XMLTV’s idea of what channels it could use I needed to add all the new channels to its config file (for me, in ~mythtv/.mythtv/Freeview.xmltv). As there were so many changes I basically did:

sed -e '/^#/d' -e 's/|.*$//' -e 's/^/channel /' < channel_ids > Freeview.xmltv

(after saving my old copy, obviously).

That done, I shut down mythbackend and backed up the mythconverg database. At least I should be able to recover if it all went chest uppermost…

Next I ran mythtv-setup on the backend server and selected the “channel editor” option so I could do a full rescan for channels. That worked fine, but gave me a large list of duplicate channels. I chose to drop them all. Also in the channel editor I updated all of the icons.

After downloading the missing icons I quit mythtv-setup, restarted the backend and checked to see if the existing listings and recordings looked correct using mythweb. They did, so I did a manual run of mythfilldatabase to check the update worked without problems.

Returning to mythweb’s setup interface, I then disabled EIT data for all those channels that XMLTV could find and disabled and/or deleted dross such as QVC. I also needed to add a few missing XMLTV ids for channels that XMLTV did have configuration data for.

And that was it. All astonishingly painless and not a recording missed. Next time I won’t put it off for so long…

Paynes Polystyrene Brood Boxes

Along with my poly nuc boxes I ordered some of Payne’s poly brood boxes, intending to use them this year with my own floors and supers. As with the nuc boxes, first impressions are good. Other reports on these had left me in two minds about them and I really wasn’t sure if they were going to be of sufficiently high quality. In fact I think I was worrying unnecessarily and I’m now fighting the temptation to order a few more before the sales end. The only real criticism I have is that I’d have preferred not to have handle recesses on the sides that are parallel to the frames and have thicker walls the entire way down.
The boxes come with slots already cut for castellated spacers, or they can be fitted with runners (my preferred choice). On the view of the bottom you’ll see that they also have cut-outs in the corners which are designed to locate on lugs in the Paynes open mesh floor which is a nice touch.
The really noticeable difference between these and the Lyson/Abelo boxes is the external dimensions. The Lyson boxes are the same size externally as a standard National. These are 15mm to 20mm bigger each way (though obviously not in height as that would muck up the bee space). I’ve taken some photos with a standard cedar super on top to show the internal and external fit. For me the largest problem this causes is that a standard National roof will not fit, but that shouldn’t be a problem I have to solve for a while.
Like the nuc boxes, these benefit from painting with water-based exterior paint. Once that’s done and the runners are fitted they’ll be ready to go.

Polystyrene Nucleus Boxes

I was going to make up some nucleus boxes this year. Quite a few people have been giving positive reports of the Paynes poly nuc boxes though, and the prices in their sale finally convinced me to buy some. They arrived this morning along with a few brood boxes and a large number of frames (also purchased in the sales) and I’ve had a chance to get a quick look at them.
Overall they look pretty good. Despite being polystyrene they feel solid, there’s a built-in feeder down one side and they come with a float for the feeder, a disc entrance cover, a clear acrylic crown cover and a snug-fitting lid. The base has a built-in mesh floor and the gap that allows the bees to reach the feeder has a slot to allow insertion of a piece of metal or plastic sheet to block access to the feeder. I assume that might be required to stop the bees building wild comb in the feeder if you have a higher volume top feeder in place. They also have lugs on the feet and roof that allow them to stack together nicely. All I need to do is paint them with some acrylic masonry paint, fix the entrance discs, put frames in and they’re ready for action.

My First Polystyrene Hive

Abelo Beekeeping Equipment sell both National and Langstroth polystyrene hives. I believe they source them from Lyson in Poland. Unfortunately their current batch of National hive bodies have incorrect spacing between the frame sides and the walls, and between the boxes. As a result they’re not selling them from their site, but they are available on ebay at a much reduced BIN price. Every now and then they auction one and they usually go for around £30. At that price I thought I’d take a punt and see how the bees took to them as the bee space problems may not be insurmountable. The hive has now arrived and here’s what it looks like (complete with a few old frames in the brood chamber). I’ve not checked the spacings yet.

Communing with Nature

The weather has been wet or overcast (or both) here for what seems like months (actually, it probably is months) and those crisp, cold winter mornings have been noticeable by their absence. This morning however we probably came as close as we’ve been all winter. The sky was relatively clear overnight and whilst there was no frost, there was a slight chill in the air and the shadows were long as the sun crept over the horizon with about the same enthusiasm as I have when poking my head out from the duvet at pretty much the same time.

This morning was brightened further by the view of deer browsing in the field behind the house. Before this week I’d not seen any for ages. They’re hard to make out in this photo, mostly because it was taken with a pocket camera in very low light:

The deer ran as soon as I went out to feed the animals and collect eggs, but thanks to the clear sky I was treated to this combination of views, first to the west:

with the near-full moon setting over the cricket pitch and on the opposite horizon, the sun rising through the hills to the east:

There are times when this is all the justification I need for living here…

The New Home Apiary

Plans the for current apiary space mean that this year my hives must move. Next to the hives I took over this year (on a bit of land belonging to a neighbouring farmer) we have a scabby patch of ground covered in ivy, nettles and brambles where a few stunted trees grow (thanks to shading by a couple of sycamore trees that have rotting trunks and are generally in a bit of a sorry state). I have decided that this area should be my new apiary. It also has the advantage of only being accessible through a narrow passageway between two walls and is a dead end, so I can put a gate on it and we shouldn’t have any visitors accidentally wandering through without realising what’s there.

The first job was to get rid of a load of the ivy and sycamore. The latter turned out to be a fun job given that some of the trunks were leaning in a direction they could not be allowed to fall. In the end I chainsawed chunks out of the trunk on the “high” side and used a chain lift and ropes to winch the tree to fall in a more suitable direction. The decent timber was chopped up and set aside to dry for next winter’s logs and the rest left in a pile to have a bonfire with. I’ve promised myself that every tree I cut down will be replaced with another, so I’ve ordered a selection of fruit trees and nut trees to arrive next month to plant around the new apiary. I’ve planted about thirty or forty trees since we got here and barely removed a dozen, so I’m well ahead of the game so far.

With the big trees out of the way and the rotting elder and ivy cleared from a large enough area we found a tree that we think is a Bullace, though this late in the year it’s hard to tell from the shrivelled fruit remaining on the tree. I’ll prune it back and keep it for the time being. Now it has some decent light it might well grow better.

The ground slopes slightly, so the next step was to get the digger in and level some ground for a shed to keep my bee suit and bulky stuff such as foundation and frames in. I intend to terrace the entire area once it is clear, having the hives on the lower levels. If necessary I might also make a shelter for storing empty hives in, but that’s a way off yet.

Screwfix were handily offering a fair percentage off some sheds late in 2011 so I bought one and it was duly delivered a couple of weeks later. The lorry driver’s satnav got him lost, and then he got stuck in the field and I had to tow him out with the tractor. I’m not sure I dare order anything else from them 🙂

I’ve now assembled the shed and stood it on blocks to keep it out of the damp, though there’s a bit of flex in the floor. I might have to push some more blocks underneath when the ground dries out a bit.

This first photo shows the levelled area ground with the new shed. The hives in the background are the ones I took over last Autumn and will be moving either to out apiaries or to this new area once it is complete.

This one is the area still to clear. The tree on the far left is a hazel which I intend to coppice. The pollen will be useful to the bees in the early Spring. Immediately in front of it and slightly to the right is the tree I believe to be the bullace.

Beekeeping Plans for 2012

During the course of 2011 I took over a number of hives from other local beekeepers wanting to reduce the number they had.

Four colonies that I took on at the start of the year were at a nearby farm, though one colony turned out not to have made it through the previous winter due to a woodpecker attack. Twelve more were actually located within a few metres of my house, in a field belonging to the neighbouring farmer. These I took over after the honey was harvested.

My first plan is to create a new home apiary area with a shed for storing kit, but I’ll cover that another time. Other than that the main issue is that I now have twenty colonies in a mixture of British National single brood, brood and a half and double brood configurations. I really need to rationalise things.

The bees I’ve kept in double brood seem to do well and get through the winter fairly easily, though I was wondering if double brood was perhaps a little too big. Brood and a half is a pain in the neck for comb changing and manipulation though, so it was a case of staying with double brood or changing to a different hive type. After quite some deliberation over Langstroth and 14×12 hives I finally decided to stick with double brood. If I were starting from scratch I may well have gone with Langstroth, but I have sixty or more National wooden supers and I’d prefer not to have to replace them all.

To address the issue of the double brood perhaps being a little too big, I’ve decided to experiment with some polystyrene hive bodies to see if the colonies get larger in the warmer environment. I have ordered enough for four double brood colonies, with one poly super to go on top of each. I have also pretty much completed all the little repair jobs to patch up wear and damage to hive bodies and supers as I’ll probably need most of those to take everything to double brood with a few singles left for swarms.

So, my current plans are:

  • Double brood colonies that weren’t set up last year will have their top brood box moved to the bottom and the bottom box refilled with foundation and replaced on top
  • Brood and a half colonies will have the super removed, perhaps by putting it under the brood box first, to move the bees out of it, and then have a new brood chamber full of foundation placed on top
  • Single brood colonies will be taken up to double brood

A friend has set up an apiary for me in one of his fields a couple of miles away, so I’ll take five or six colonies there, swapping two into polystyrene hives.
I’m also talking to someone else about a second out-apiary where I know large quantities of field beans and oilseed rape are regularly planted. If possible I’ll move another five or six colonies there.
That should leave me with between four and eight colonies at home depending on how well they come through the winter. If I can find someone a little further away I may well look to set up a third out-apiary with some of those. Either way, it will mean a good reduction of hive numbers at home from sixteen or more, which should be a benefit in terms of available forage.
There are lots of other issues to think about, too. I need to move the three colonies at the farm onto mesh floors as they’re still on solid ones. The Dartington style floor appeals to me, though it’s more work to make. I need to re-think my record keeping to be able to handle a 400% increase in hive numbers, and to decide how I’m going to keep track of which kit has come from which hive at which apiary so I don’t start mixing things up.
I also want to investigate the possibility of drone-culling as a method of varroa control. I might well build some special frames for drone culling and put one in each hive.
Finally, I need to make sure I have enough clearer boards, insulated roofs, feeders, nuc boxes and so on to get everything through next winter.
It’s not like I’m going to be short of things to do…

Home-built Honey-warming Cabinet

I have about 90kg of oilseed rape honey that has solidified and obviously before I can turn it into soft-set honey I need to melt it again. Warming cabinets are far from cheap to buy and it’s not exactly hard to build one, so I decided to do just that. It doesn’t even need very many parts. I started with:

  • A broken 600mm square chest freezer (that I’ve actually used for storing chicken feed in for a few years, though my original intention was to make it into a smoker)
  • A 120mm diameter fan from from a PC power supply that I’d scavenged from a dead PC
  • A 60W Danfoss tubular greenhouse heater, about £12 from ebay
  • A hot water cylinder thermostat. Not all have a wide enough range, but I found a Siemens model that went down to less than 30C which is sufficient. £11 from Screwfix, I believe
  • An aluminium CPU heatsink, also scavenged from a dead PC
  • A 6V wall-wart power supply (originally came from a Sony Discman)
  • A surface-mounted 13A mains socket
  • A length of 3-core electrical cable
  • Some scraps of wood

Everything except the thermostat and heater were lying around in the workshop, and I even found another suitable thermostat later on. I know some people use 60 watt light bulbs as a heat source, but we have a lot of trouble with bulbs blowing here, and as light bulbs aren’t really designed to be on for long periods of time in confined spaces it would probably just exacerbate the issue. Incandescent bulbs are becoming harder to get hold of, too.

The heater needed to be mounted horizontally (so the instructions said), so I first fiddled about to see how I could arrange things to fit most containers into the freezer compartment. With the heater across the centre of the compartment floor there was easily room for four 15lb honey buckets, but 30lb buckets would be marginal. With the heater across the back, two 30lb buckets should fit easily, but there’s only room for three 15lb buckets. If I build a platform across about a third of the compartment over the top of the heater however, I’d still get two 30lb buckets or five 15lb buckets in, so I eventually settled on the second arrangement.

I don’t have photos of the construction process, but hopefully the picture at the end should demonstrate what I did clearly enough.

I wanted some protection for the heater so it wouldn’t easily get honey spilt on it (I may also use the cabinet for warming comb), so the first job was to make a cover out of wood (which in fact the heater also mounts onto). I made two holes in the cover, one at each end. Over one hole I fixed the fan so it is drawing air over the heater and blowing it around the cabinet.

I then took the heater power cord and connected it to the thermostat, with another length of cable going from the thermostat to the back of the 13A socket. I ran a longer cable through a small hole in the freezer wall to power the socket and put a plug on the other end. Now the socket is live when it’s plugged in at the wall, but the heater is controlled by the thermostat.

I used wire to fix the thermostat to the flat side of the heatsink and fixed the heatsink to the heater cover just by screwing through the wood until the screws bit into the vanes of the heat sink.

Power to the fan comes from the wall-wart plugged into the 13A socket. It’s a 12V fan running at 6V, so it’s turning more slowly than intended, but that’s no big deal for this.

The final touch was to put a rack on the freezer compartment floor to allow air to circulate beneath the honey containers.

Here’s a photo of the insides, with a few honey jars with crystallised honey for testing. I also put a thermometer inside to see how well the temperature matched the thermostat. It’s not that accurate, to be honest. I think the thermostat reads about 5C high.

If it works well then it’s a design I might well use again on a larger scale. A 1200mm wide chest freezer would quite possibly hold 300lbs of honey, which is more than enough in one hit for the time being.

Varroa Treatment with Oxalic Acid

On Sunday I treated my bees with oxalic acid as part of my varroa mite management. The general idea is to pick a time close to Christmas or New Year when there is hopefully no brood in the hive and the colony is clustered for warmth over winter. Each hive is quickly popped open, 5ml of the oxalic acid/sugar syrup mixture dribbled over each “seam” of bees and the crown board and roof are then replaced before the bees really have time to react.

This year is different, however. Because it has been so mild my colonies have not clustered at all and are still flying regularly. Because that may increase their food requirements I’ve taken the preventative measure of putting a QX and eke on top of each hive with fondant resting on top of the QX (so it doesn’t drop down between the frames). Opening each hive is more disruptive as a result and takes a few seconds longer, by which time the active bees are flying out of the top of the hive, somewhat less than amused by the intrusion and pretty hacked off once they’re covered in the oxalic acid solution. I don’t blame them, but it was a fair from pleasant experience and I picked up a sting on my wrist (through my suit and gloves) where a couple of bees had become caught in the folds of the material.

Most of the colonies had started using the fondant, with one (a swarm I took last summer) getting well into theirs. Now through to March is really the danger time for starvation so I need to keep an eye on the situation there.

Unfortunately two colonies look to me as if they are unlikely to make it through to winter. They were being badly attacked by wasps during October and whilst I moved the hives to a different position in the apiary to make them harder for the wasps to find, they look like they’ve lost the will to live. I shan’t be counting on them in my plans for the coming season and if they do make it I’ll consider it a bonus.

The remainder of the colonies appear to be doing well, with some hives having as many as eight seams of bees present. I just hope that the strange weather conditions haven’t affected their ability to make it through to the Spring and that they don’t run into trouble if we have a sudden cold snap in the next couple of months.

Today I have to go and treat three colonies that I look after for a local farmer. The forecast for today was sunny, but it doesn’t seem to be living up to expectations. Hopefully the rain will at least hold off so treatment is possible.
