May 2007 saw us spawning our own fish again ready for sale in June.this year we are spawning doitz kohaku,doitz sanke,kujaku and hariwake


parent fish were chosen then anaesthetized

fish were weighed to determin the correct dose of hormone

pituitary gland hormone powder was disolved in saline and split into male and female strength stock solution

syringes are pre loaded with the corresponding dose of hormone

fish are injected

then taken to the recovery tank


10 hours later the process is repeated

injection site is massaged to minimise the loss of injected fluid

then we wait

and watch for eggs on the bottom of the female holding tank

sperm is taken from the males,labled and stored in glass pots in the fridge

eggs are then stripped from the females into bowls

bowl of eggs

sperm,eggs and water being shaken for 30 minuites

a de-gumming solution is added and shaken for a futher 1 hour

eggs are rinsed and transfered to the hatchery
after 60 hours at 25 degrees the eggs hatch and fall into the growing on tank

watch this space for developments as they happen
