FEEDING FISH.

Feeding fish accounts for about 65-75% of total cost of production,hence there is a need to understand the requirements of fish,the feed stuff ,and how to get the desired value for the cost of feeding. Fish feed must be a balanced meal consisting of carbohydrate,protein,fat and oil,and vitamin premix.The sources of these component will depend on availability,cost and weighed advantages of the feed stuff over other options. Carbohydrate sources can be any of the following; millet,maize,wheat,rice bran or sorghum.Protein sources include; soya beans,fish meal,groundnut cake.Fat and oil include palm oil,vegetable oil or fish oils.The vitamin premix is a combination of additives and supplements . Atovi premix is the choice for enhanced growth and early harvest. The combination of these various feed stuff depends on the age of the fish with regards to the crude protein level,and stage of development.Fish feed must posses certain qualities for it to be considered suitable for use; 1)it must be balanced;contain all components in required quantities. 2)it must be attractive and palatable to fish. 3)it must be cost effective. 4)must promote growth of fish. 5)must be stable in water but must not pollute the pond. fish feed depends on the management employed; feeding may be by using natural feed,compounded feed,live feed or a combination of natural and compounded ration.The compounded feed are presented in powdered ,granular or pelletized forms.Fish feed could also be presented in flakes,this is usually the form for ornamental fish.Natural feed include the normal feed that fishes are exposed to in their natural habitats such as aquatic weeds,water hyacinth and water lettuce. Phytoplankton,zoo-plankton,insects,shrimps,maggot,tadpoles and earthworm. Animal offals are also sometimes used to feed fish; these offals include chicken intestine,pig scrapings, and cattle cuttings. The offals are washed properly,boiled and then coated with cornflour to absorb oil,this is then fed to the fish.The flour helps prevent pollution in pond by limiting /preventing oil deposits. Eggs can be used as well; the eggs are boiled,shelled and the yolk is mixed with water to form a paste.This is then broadcast ed on the pond for fish to feed.The disadvantage of feeding with yolk is that the pond must be flushed after every meal to prevent contamination of pond. Fish are fed at specific times to create a rhythm/pattern,the feeding is done at specific points so that the fish can be easily observed and weak/inactive ones are isolated. The quality and quantity of the feed is important,as it plays a vital role in the success of the production.When feed is incomplete,inadequate and has potential to pollute pond,these hampers the growth and development of fish.

MYIASIS IN DOGS.

Myiasis is a skin infestation of the coat of animals, also occurs in man. Myiasis occurs in most species including rabbit, the difference is in the species of fly that causes the infestation.

 Myiasis is also referred to as fly strike. Myiasis though seasonal ,usually occurs in animals with soiled coats due to diarrhoea, open wounds,  and urine stains.
 Myiasis in dogs occurs when the bot fly lays eggs on moist coat of dogs, the eggs hatch in 1-2 days into larvae which are actually maggots,this burrow into the coat causing irritation and pin point protrusions .
