Description The dynamics of Nemipterus japonicus stocks along the north-east coast of India was studied using landings data from 2012-2015. Annual average landing of the northern region was 1251 t and that of the southern region was 2980 t. Growth was found to be allometric in the northern region and isometric in the southern region. Von Bertalanffy growth equation was Lt = 33.02 [1 – e – 0.38 (t + 0.0625)] in the northern region and Lt = 29.87 [1 – e – 0.42 (t + 0.0585)] in the southern region. Natural mortality, fishing mortality and total mortality ranged from 0.92 to 1.01, 0.51 to 0.57 and 1.43 to 1.58. Exploitation ratio varied between 0.35 - 0.36 and exploitation rate between 0.27 – 0.29. Annual average stock, standing stock biomass and maximum sustainable yield were 4611 t and 10403 t, 2453 t and 5228 t and 1754 t and 4130 t for the northern and southern regions.
