In this study, mitochondrial DNA analysis using 16S ribosomal DNA (rDNA) was performed to investigate the phylogeny relationship of Trichiurus lepturus in the Persian Gulf compared to the other investigated area. The amplification of 16S rDNA resulted in a product of 600 bp in all samples. The results showed that the isolated strain belongs to T. lepturus showing 42 divergence sites among the s...

Ribbonfish, Trichiurus lepturus (Linnaeus, 1758), is an important component of subsistence fisheries throughout its tropical and subtropical distribution. The catch rate of ribbonfish has increased seven-fold in a decade in the Persian Gulf and Oman Sea. We collected monthly biological samples from T. lepturus, to estimate growth and mortality parameters, and identify species reproductive patte...

The size selectivity and catch pattern of Trichiurus lepturus in 40 mm diamond square mesh codends were investigated this study. A 34 m high opening trawl was used, which is a common design used by fishermen operating along the northwest coast India, cover codend method employed to determine selectivity. Along with changes length at 50% retention rate for usage codends, indicators understand ex...

Fishery resources assessment is the basis of scientific management and sustainable development fisheries. Trichiurus lepturus , one major commercial fishes in East China Sea, great significance to study its stocks status. Based on length frequency data T. collected Sea from 2016 2020, we estimated asymptotic length, optimal at first capture, relative mortality, biomass stock using length–based ...
