| Summary: | Length-frequency samples of Nemipterus bathybus Snyder (Pisces: Nemipteridae) obtained in a
trawl sU11ley off the coast of Sarawak, East Malaysia (South China Sea) were separated into components
using the Bhattacharya method. The mean length of adjacent components. assumed to represent year
classes, were used to estimate the parameters Loo and K of the von Bertalanffy equation, while the
numbers of fisah in these components were used to estimate total mortality. Results were: TLoo = 31.2,
K = 0.36 year-1 and Z =1.4 year -1. The results are discussed in relation to other estimates ofN. bathybus
and other species of threadfin breams. |
