Growth, mortality and stock assessment of Osteogeneiosus militaris (Linnaeus, 1758) from Veraval fishing harbour, Gir-Somnath District, Gujarat

Abstract

The present study was undertaken to assess on aspects of growth, mortality and stock assessment of Osteogeneiosus militaris from Veraval fishing harbour. The species found carnivour feeding habit and principle food preference was crustaceans crustaceans, mollusc and small fishes. The estimated growth parameter for Osteogeneiosus militaris (Linnaeus, 1758) was 523 mm and 0.62 for L∞ & K respectively. The estimated mortality parameter for the species was 1.09, 3.67 and 2.58 for Natural mortality, total mortality and fishing mortality respectively. The fecundity found in the range of 23 to 75. Gestating males found incubating eggs in the range of 49 to 55. The pooled length-weight relationship is Log W = - 4.74567 + 2.825541 Log L.
