Title Growth, mortality and stock assessment of
Nemipterus mesoprion (Bleeker) from Mumbai
waters
 
Creator Chakraborty, S K
 
Subject Stock Assessment
 
Description Growth, mortality, stock and yield parameters of Nemipterus mesoprion
(Bleeker), based on the data collected from 1989-’94 is reported here. The VBGF
parameters in length for this species were estimated as follows. L00 = 274 mm,
K = 0.7628 (annual) and t0 = -0.0011764 years. This species grows to 147, 216
and 252 mm at the end of I-III years of its life. The average total, natural and
fishing mortalities were calculated as 2.55, 1.57 and 0.98 respectively. The average
exploitation ratios and rates were calculated as 0.384 and 0.354 respectively.
The total stock, biomass and MSY were estimated as 3991.5, 1413 and
887 t respectively. The yield per recruit study shows that it can be raised by
increasing the age at first capture and fishing efforts.
