One of the problems faced in development marine and fisheries sector nationally is low quality fish capture due to limited capacity quantity available port infrastructure resulting decrease competitiveness. The data this study were related from fishing boats wholesalers. obtained was observation location vessel, auction place, marketer. types taken Kurisi (Nemipterus pneumatophores), Biji Nangk...

Many phoretic relationships between arthropods are understudied because of taxonomic impediments. We here illustrate for avian lice riding on hippoboscid flies how new natural history data can be acquired quickly with modern and cost-effective barcoding techniques. Most host-specific, but some arrive hosts by hitchhiking that feed bird blood. Our summary the literature yielded 254 published rec...

Assessment of fish stock status is generally required for fisheries management, which difficult when the data are limited. The length-based Bayesian Biomass (LBB) approach a powerful and new method, where only length-frequency used estimating resources. Here, we applied LBB method to assess seven commercially valuable marine fishes from northern tip Bay Bengal (BoB), Bangladesh. These species w...

In aquatic environments, many prey animals possess damage-released chemical alarm cues that elicit antipredator behaviours in responsive con- and heterospecifics. Despite considerable study, the selective advantage of alarm cues remains unclear. In an attempt to investigate one of the more promising hypotheses concerning the evolution of alarm cues, we examined whether the cue functions in a fa...

While it is generally assumed that specialist species are more vulnerable to disturbance compared with generalist counterparts, this has rarely been tested in coastal marine ecosystems, which are increasingly subject to a wide range of natural and anthropogenic disturbances. Habitat specialists are expected to be more vulnerable to habitat loss because habitat availability exerts a greater limi...
