Fish information

 Vetark Professional offers a range of products for fish including disinfectants, anaesthetic and parasite treatments by Fish Treatment Ltd. In this section you will find information regarding genereal husbandry as well as getting the most out of our products,

Some general pondfish information to get you started:

  • Fish will maintain body weight when fed 0.5-1.0% body weight per day, for growth feed extra - up to 3%.  ie. a 1kg koi will eat 10g pellets per day
  • Adding vitamins to fish food
  • Use agar (or gelatin, but agar is better) to make a solution and add the vitamins, then coat the food with the suspension and allow it to dry, about 50ml/kg of pellets. Good quality fish or corn oil can be used as an alternative - less is needed since a fine coating for -'stickiness' is all that is required. This can then be stored in a plastic bag in the fridge for a week. New food should be made up weekly if prolonged courses are intended.
  • Make a koi cake with pellets, prawns etc and include the vitamins with agar and put the mix in the freezer poured into an ice cube tray. This way a cube can be popped out as necessary.
  • Minimal handling pays dividends, always try to use oral antibiotics instead of injectable ones whenever possible.
  • Always consider the effects on filtration of whatever you add to the water.

Avi-sol Vitamin solution - great for ex battery hens! -

 I've been using avi-sol vitamin supplement in my work re-homing ex battery hens. It's proven to be a valuable resource in supporting particularly weak and vulnerable hens through rehabilitation. Highly recommended to anyone wanting to help ex battery hens.
