The effect of eyestalk ablation on the growth of giant freshwater prawn Macrobrachium rosenbergii de Man

Abstract

This study is to examine the effect of eyestalk ablation on the growth rates of Giant Freshwater Prawn, Macrobrachium rosenbergii de Man. A study was conducted over 91 days showed different results on two different groups of prawns. One group is the normal group and no such treatment of a subject, while another group is a group of prawns that received treatment. The results showed that the method of ablate the eye of prawn has been stimulating the growth of prawns. The main objective of this study was conducted to determine the effect of eyestalk ablation on the growth of prawns. Besides that, this study aims to investigate the pitch between the frequencies of prawn to molt on growth rates. According to the facts and the results of previous studies that have been done by many researchers, the animals under the 'crustacean' capable of molting more frequently than normal rate of growth and development that are rated at a faster than normal when cut or the eyes blinded. In addition, this study was conducted to investigate the difference between growth rates of male and female prawns.
