Effective recreational fisheries management requires a balance between fisher enjoyment and compliance with regulations perceptions can be useful to understand whether the is right. Our study collected insights via an online survey into within shore-based Peel-Harvey blue swimmer crab fishery in Western Australia. Overwhelmingly, participants self-reported as complying regulations; positive fin...

BACKGROUND Seafood processing workers have an increased risk of developing occupational asthma. This has not been studied among Norwegian crab processing workers, nor has the respiratory health of exposed workers been compared to a control group. OBJECTIVES Assessing the impact of working in the crab processing industry on workers' respiratory health. DESIGN A cross-sectional study of the r...

The willingness of the cephalopod mollusc Octopus vulgaris to attack a live crab is traditionally used as a method to assess the overall health and welfare of octopuses in the laboratory. This method requires placing a crab in the home tank of an animal, measuring the time (latency) taken for the octopus to initiate an attack and withdrawing the crab immediately prior to capture. The same crab ...

Abstract Blue swimming crab (Portunus pelagicus) is one of Indonesia's highest-export fishery commodities. Capture fisheries are dominated by fishermen with low productivity, efficiency, and income levels. There a high-profit disparity between upstream downstream actors, where get the lowest profit. This study aims to identify causes profit disparities supply chain actors propose model solve pr...

Transient low-oxygen patches may have important consequences for the population dynamics of estuarine species. We investigated whether these transient hypoxic patches altered population dynamics of the commercially important blue crab (Callinectes sapidus) and assessed two alternative hypotheses for the causal mechanism. One hypothesis is that temporary reductions in habitat due to hypoxia incr...

Shrimp milkfish cultivation a form aquaculture that widely developed this village. In addition, there are also crab catching activities. Community empowerment activities through use existing land for development vaname shrimp cultiv...

Reforestation is one of the Philippines’ government efforts to restore and rehabilitate degraded mangrove ecosystems. Although there is recovery of the ecosystem in terms of vegetation, the recovery of closely-linked faunal species in terms of community structure is still understudied. This research investigates the community structure of mangrove crabs under two different management schemes: p...

Drift macroalgae, often found in clumps or mats adjacent to within seagrass beds, can provide additional food resources and habitat complexity, leading increased animal abundance, but large concentrations also inhibit faunal movements, smother benthic communities, contribute hypoxia, reducing nekton abundance. Despite its ubiquity, few studies have quantified drift macroalgal prevalence over sp...
