Meat yield studies in Harpiosquilla harpax (de Haan, 1844) and Oratosquilla anomala (Tweedie, 1935) (Crustacea: Stomatopoda) represented in the shrimp trawl net by-catches off Visakhapatnam, east coast of India

The meat yield of Harpiosquilla harpax and Oratosquilla anomala was studied, because these two species form an important component of the shrimp trawl net by-catches off Visakhapatnam during January - December, 2009. The mean value of meat yield noticed was 34.53% ± 3.04 and 36.59% ± 2.58 in males and female of H. harpax respectively. The meat yield in females was little higher than males. The mean value of meat yield in O. anomala reported was 39.56% ± 2.55 and 39.49% ± 2.55 for males and females respectively. The average mean value of meat yield was almost equal in both sexes. The mean value of meat yield in two species indicated that, O. anomala has higher meat yield than H. harpax. The highest meat yield was observed during monsoon and lowest during premonsoon in both the species. Analysis of variance showed that the meat yield was statistically not significant (p>0.05) between the sexes in both species in the present study.
