Abstract

Abstract

A new method to rapidly estimate the body weight of the crossbred juvenile abalones was established for determination of the amount of microencapsulated feed for the aquaculture.Ten batches of the abalones was collected for observation.A total of 1 670 data sets on body weight(W)and shell length(L)of the abalones were gathered to arrive at a regression equation:W =0.133 L^2.985(R²=0.987).By using a newly developed IPP image analysis,500 sets of Ws and Ls on the randomly selected abalones were measured to compare with the estimated data to examine the reliability and accuracy of the prediction equation.From the equation,the feeding rate per10 000 crossbred juvenile abalones at different water temperatures could be obtained.
