This is the time of year that many fisheries have their draindown and netting, in order to remove unwanted fish and bring the overall biomass back to acceptable levels. This week I have helped in one lake netting and will be assisting in a couple more before the weeks out. Some interesting aspects of fishery management became apparent at the recent netting and several points are worth a mention. The lake was around 5 acres in size and in addition to the existing stock a ton of good carp were stocked at the end of 2005. As well as a good head of 20’s and 30’s the owner also purchased a couple of 40’s for close to £1000 each. In the time since then a great deal of work has been carried out to improve the fishery, however one thing that was neglected was the regular feeding of the fish. Financial considerations always play a big part in how much food is put in and also the quality of the food in question. In this case it was deemed that the money available was better spent on improving facilities rather than buying several ton of pellet each year. The outcome was a real eye opener with a good head of stunning but rather slim fish showing up. The largest was just 31lb !!! There were other considerations that would have impacted on lack of growth, in particular a large head of poisson chat. Thousands of the dreadful little things were disposed of and the owner will now have to quicklime all the puddles and wet silt to ensure none are left to repopulate the lake. They are such aggressive feeders that wherever they are present it not only upsets the anglers but also makes deep inroads into the natural food supply. For those that have never met a pc I will describe them. They are like a small catfish (same family) but with spines on the dorsal and each pectoral fin. Sharp spines I will add as my thumb took a few during proceedings and very painful there are too. They only grow to about 8ins generally but the parents are very aggressive guardians of their young. The fry will swim round in a large ball formation with the parents swimming around it and attacking any potential predators. In fact as far as I am aware the only real predator on poisson chat is their larger cousin the silure or Wells catfish. Hopefully the fishery owner in question will enjoy much better luck with his growth rates now that the nuisance species have been removed and a regular feeding pattern is introduced.
On thursday we will be helping with the netting of the lake just over the road from Etang Mèe. With French owners everything will be done in typical French fashion. Mostly small fish are likely to be found and the day will see everyone round the sorting table where buckets of fished are poured on and sorted into bins of different species. A warm afternoon watching thousands of roach, pike, carp and tench gasping away in just a few inches of water is hard to get used to. What does surprise me about this particular lake is that so few small fish are returned to grow on and yet, the next draindown 2 yrs later will see literally thousands of fish in the net.
Saturday will see Jimmy and I helping at Etang Rendezvous where our friend George is having his first ever netting since he purchased the lake in 2002. Besides a good head of big carp the lake contains around 50 big catfish running up to over 100lb. Should be an interesting day!!!!
Back home the carp are still pretty active with temperatures being very mild for the time of year. Surprisingly, most action seems to be in the shallower water with plenty of big fish crashing out at dusk. We will start letting water out of the main lake later this week to enable us to carry out work on the swim fronts and also cut back tree’s and remove snags. If we can get the work done in time we can then top up the lake levels by opening the valve and letting Poplars drain into it. Our hope is that we will then be able to net Poplars to remove all the smaller fish leaving a good head of bigger ‘growers’ to be fattened up over the next couple of years.
With all this work its a good job I am still so young and fit !!!!!
