Abstract

Cherax quadricarinatus, or known as redclaw crayfish is a freshwater species. It is endemic species to freshwater habitat of North Australia and Southern Papua New Guinea. This study is to find out the relationship of food type with the stored of energy and the best type of the diet for culture based on the value of hepatosomatic index and body weight gain. All the crayfish were cultured under three different treatments which were commercial feed treatment as control, soy bean treatment and tilapia flesh treatment. The culturing of crayfish was conducted for 28 days and were dissected after 28 days of cultured. All the water quality parameter such as turbidity, dissolved oxygen, pH, conductivity and temperature were collected. The body weight gain, specific growth rate, hepatosomatic index and moisture content of liver were calculated. The highest body weight gain and specific growth rate was tilapia flesh treatment and the highest hepatosomatic index and moisture content of liver was soybean treatment. There were no significance differences (P<0.05) among three treatment. The best type of diet were determined which is tilapia flesh where soy bean can reduce the growth of redclaw crayfish.
