Utilization rate and length-weight relationship of shortfin scad (Decapterus macrosoma) in Bali Strait Indonesia

Shortfin scad (Decapterus macrosoma) is an essential economic fish resource that spreads over tropical and subtropical oceans and is mostly caught in Bali Strait. High market demand for this fish leads to an increase in fishing efforts. In contrast, uncontrolled fishing efforts will threaten its sus...
