Unregulated fishing impact on yellowfin parrotfish scarus flavipectoralis in Spermonde Islands, Makassar Strait, Indonesia

The Spermonde Islands are a group of islands located in Makassar Strait, which stretches from the coast of the Takalar Regency in the South and to the coast of Barru Regency in the North 2,500 km2 . These waters are the fishing areas of artisanal fishermen who catch reef fish, such as the yellowfin parrotfish Scarus flavipectoralis. Yellowfin parrotfish is a Scaridae that lives in shallow waters in tropical and subtropical areas, especially in coral reef ecosystems. Yellowfin parrotfish is included in the Least Concern group, a species threatened by fishermen's catch if not adequately regulated. The exploitation of Yellowfin parrotfish in Spermonde Islands, Makassar Strait, Indonesia, has never been studied. This study aims to analyze the exploitation rate of yellowfin parrotfish in the Spermonde Islands waters. The
yellowfin parrotfish Samples were taken from the catch landed at the Fish Landing Port, Makassar City. The growth rate was Lt = 40 [1-e -0.28(t-0.5505)]. The total mortality rate was 3.29, the natural mortality rate was 0.73, the fishing mortality rate was 2.56, and the exploitation rate was 0.78. This exploitation rate indicated the unregulated fishing impact on yellowfin parrotfish, and if this unregulated fishing continues, the yellowfin parrotfish could become extinct in Spermonde Islands.
