If you can imagine, when you drain a lake you are left with lots of little puddles of water on the lake bed and these frequently contain very small fish, anything from roach to perch fry, along with tench and the odd small jack pike. Most of these fish will not survive more than a few hours and that's if they can evade the Heron & Egrets capitalising on the easy free meal. In the past I have observed Marsh harrier working the lake beds, along with night raids from Boar, Fox & even Pine Marten. Once the bulk of the fish have been removed a team of men will then work the remainder of the lake bed in a grid fashion just to make sure nothing has been missed.
Unfortunately with fingerling size fish it’s almost impossible to save them all and I justify this by the bird life capitalising on the free meal over the harsh winter period so nothing is lost or wasted....which is always the case with the natural environment. One year all the tench had been harvested and graded into large tanks that are loaded onto a pickup ready to be transported. This particular evening the weather had been cruel and the fish dealer arrived late, so we worked into dark with hands the colour of blue steel and core body temperatures that felt like the inside of a chest freezer. With the job complete, we retired for the evening, cold and wet and tired. The following morning we awoke to -4oC and a hard frost carpeting the outside world.....after slipping back into the frozen waders and preparing for the daily events, I noticed a small tench no longer than 4" long frozen to the pickup bed. It was frozen solid to the steel and I could not prise it off. As I stopped and took a close look, pitying my mistake, I thought its eye moved slightly within its socket.....it cannot be I thought, so I gathered a bucket of water and poured it over the fish to defrost it off the steel floor. After quickly transferring into a bucket of water, within 10 minutes that fish was swimming around. Now I know that's hard to believe because that fish had spent a minimum of 12 hours out of water and was then frozen solid in -4 oC temps and it still survived! Unbelievable and just goes to show when a lake freezes in winter and the fish bed down into the soft silt to enter a dormant state, they have little to worry about compared to that poor chap.
Once again his little red eye swivelled in its socket, I placed him into the bucket to defrost, washed his flanks to remove the frozen debris and as can be seen from the series of pictures you can see how miraculously it comes alive and swims away to fight another day. Now if that's not one of nature’s miracles!
