Trout fry

Been up the fish farm this morning for a hour or two and i am yet again impressed with how well the fry are coming on.The top picture i took this morning and the bootom one is from last week as you can clearly see the orange sack has shrunk a little bit and the tail has started to develop. There are already a few fry that have started to swim to the top of the hatching trays which is a tell tale sign that in a week or to they will start to feed on trout food dust and them the hatching grid cab be taken out. the orange part is called a yolk sack and the fry uses this as a food sorce until the are develped enough to feed. So as you can see it wont be long until they are on the feed, also in the grounds of  the farm there are two settling tank which the stock pools run into and the fish waste settles then the clean water runs back into the river rhondda there where a mass of midges hatching over them i did take a photo but my phone camera would not pick them up. it has been quite mild over the last couple of weeks and there have been alot of these hatching from the shit pools as we call them up the farm.
