ABSTRACT
The high market demand for endeavour shrimp (Metapenaeus ensis de Haan) has caused intensive fishing
for this resource and tends to threaten their sustainability. Assessment of
fishing dynamic and stock status of fisheries resource is the main point to formulate
its proper sustainable management in the future. The purpose of this study was
to determine the stock status of endeavour shrimp in the Bombana and its
surrounding waters. The study was conducted from April to November 2021 using a
survey method to analyze the length at first capture (Lc),
length at first maturity (Lm), growth rate (K),
maximum theoretical carapace length (Loo), and mortality rate such as
total mortality rate (Z), fishing mortality rate (F) and natural
mortality rate (M). The study results revealed that the endeavour shrimp
growth pattern in Bombana was negative allometric and that the ratio of males
and females was not balanced. The length at first capture (Lc)
was 29.83 mm (carapace length) and the length at first maturity (Lm)
was at a total carapace length of 31.67 mm. The growth rate (K) was 1.0
per year and maximum theoretical length (L∞) was 46.2 mm. The
estimate total mortality rate (Z) was 2.52 per year, the fishing
mortality rate (F) and natural mortality rate (M) were 0.91 per
year and 1.61 per year respectively. The exploitation rate (E) was 0.36 per
year, therefore the stock status is not categorized overfishing. In order to
ensure the sustainability of the endeavour shrimp, then the effort must be
increased by about 28% of the current effort.
