Quick tadpole question - not growing
The tadpoles hatched from the frog spawn and looked pretty lively.
They were decanted into a plastic tub full of rain water which was buried in the ground to form a mini pond. Some bricks were added to provide a platform for mature froglets to use to escape. Plenty of pond weed for food. Move on several weeks and it is hard to find any tadpoles, and those located are still tiny and are not moving. Internet searches suggest that one reason could be very cold water. It has been very cold this last month with air frosts nearly every night and it was a very chilly April, and May isn't looking much better given the sleet and hail. Has anyone else had problems with tadpoles growing? Water seems fresh, there is algae and water weed for food. If not the cold (and the water was screened for predators and a Mayfly larva evicted to another tub) are there any suggestions as to likely cause?

Cheers Dave R Not an expert but sure there will be plenty here. It took some time for frogs to use my pond, or the butler's basin sunk in the ground at the allotment. I think you may have to keep trying. This year, frogs laid in the sink on the allotment so I guess last year's transport was a success. Perhaps neglect and patience are the missing ingredients. This year's tadpoles are fine, but they are not interested in the small thin strips of cooked chicken I have offered them in the past. Amazing how the numbers steadily decline. Cannibalism I suppose. Darwin was right. The survival of the least edible. |

Move on several weeks and it is hard to find any tadpoles, and those located are still tiny and are not moving. They are carnivorous and if there is nothing else to eat will eat each other. Try ants eggs, live water fleas or fish food flakes to fatten them up. It is so cold right now that I expect they are almost in stasis. We had snow on the ground this afternoon and on Saturday. I don't expect this year to be any good for plums, pears or cherries - they have all taken a battering in the past couple of day. Hardly any flying insects either. Swallows and house martins were wise to be late. Internet searches suggest that one reason could be very cold water.

If not the cold (and the water was screened for predators and a Mayfly larva evicted to another tub) are there any suggestions as to likely cause? My guess is shortage of food leading to cannibalism. -- Regards, Martin Brown |

Swallows and house martins were wise to be late. I have a large "colony" of mason bees (many hundreds of filled tubes) and haven't seen more than a few this year. They usually come out on mass just as my cherry tree is in full blossom. So, after a few days of very heavy winds that have cleared my cherry tree of all blossom and a possible lack of pollinating insects I too don't give out much hope for a bumper crop of cherries. My crop last year wasn't too good - despite many cherries on the tree a complete lack of rain for a couple or three months followed by a wet week meant that the first of the cherries swelled with little taste followed by quickly splitting skins and mould setting in. The very small crop gathered in the in the sweet spot before spoiling were nice :) -- mailto : news {at} admac {dot} myzen {dot} co {dot} uk |

Received wisdom is that tadpoles start out vegetarian and live on algae and other plants. Later on in their development (around when the develop front legs) they become carnivores and we have some late stage tadpole food for when (if) that happens. One reason we were checking the tadpoles was to see how far along they were with their development. Answer was - not very far along at all. I'm assuming that if they had turned carnivore there would be a small number of large tadpoles looking suspiciously well fed.

I'm assuming that if they had turned carnivore there would be a small number of large tadpoles looking suspiciously well fed. I'm not an expert but have adjoining rockery ponds, about 3' above ground in this property that we moved into 5yrs ago. Last year there were no tadpoles and the water wasn't nice so totally emptied, cleaned and refilled (water butt rainwater, water butts also cleaned) and we had 4 lots of spawn in March. Now have both ponds brimming with tadpoles some bigger than others quite happily going along the edges of the ponds eating the algae. Not added any food. My understanding also is as they turn into froglets they get teeth and become carniverous and hopefully will start devouring the daphnia that are forming in the pond. Apart from cleaning the ponds I'm hoping to leave nature to nature. In the East Midlands and there's been thin ice during the growth period but otherwise a sheltered spot. Not sure if this is of any benefit to the OP other than the tadpoles seem ok here. -- AnthonyL Why ever wait to finish a job before starting the next? |

If you want your ponds to be full of interesting wildlife, don't put fish in them, otherwise you'll only have fish. That's not the case in our (small) pond, we have [gold]fish, lots of them, but we also have newts, tadpoles at the moment, water beetles, etc. etc. I'm always spotting surprising new things in there. -- Chris Green ยท |

Thought the pergola over the pond would be a deterrent with established vines growing all over it but the wild life camera caught the heron in the act gobbling the fish, some of the fish were nearly ten years old. We may restock the pond again with fish and put the netting back which we had not needed for 18 months until the other morning. Stephen -- |

Of course it's possible the newts have eaten them. Or those **** ducks I keep chasing off... They'll be back next year. There's been a pond in that area for at least 100 years. Andy |
