—Many aspects of small-scale fisheries hinder our efforts to understand their dynamics, as required for sustainable management. For example, there is no widely accepted definition of small-scale fisheries or global data on number of small-scale fishers and their catches. One reason for this is that most research on small-scale fisheries is done at community level and tends to focus on immediate...

Abstract The giant mud crab, Scylla serrata (Forskål, 1775), is a targeted fishery along its geographic distribution, both for domestic and international markets. Population genetic data, evaluated with markers such as microsatellites, can be used to identify management units (stocks) based on dissimilarities between locations, informing localized decisions fisheries. Additionally, microsatelli...

Despite its importance in fisheries studies, there is insufficient understanding on the effect of sampling error or bias individual growth and other stock indicators. We show influence sample length distributions parameter estimates, illustrating with an example. For brown swimming crab, we simulated samples five configurations estimated parameters von Bertalanffy (k, L∞L∞ , t0), asymptotic wei...

Capture of recently molted soft-shell crab in the Newfoundland and Labrador (NL) snow ( Chionoecetes opilio ) fishery is undesirable due to resource wastage associated with low meat yield supposed high mortality rates upon discard. This study intended formalize best-practice management advice for avoidance fishery. The investigates factors affecting incidence catch across a large geographic sto...

Surveying free-ranging crab populations is important for monitoring the health of exploited stocks and predicting future productivity. Here, we present a novel research trap design use in fisheries-independent surveys blue swimmer (Portunus armatus) populations, evaluate against some existing approaches within an independent survey framework. Specifically, aimed to improve efficiency capturing ...

Crabs—those sometimes pesky, hard-shelled beachcombers—are a highly diverse animal, with some 7,000 species found in oceans, lakes, and on land, varying in size from the diminutive pea crab (millimeters) to the giant 4-m wide Japanese spider crab. Tsang et al. (2014) have constructed the most complete and extensive data set to date. Their recalibrated crab gene tree using DNA and mitochondrial ...

Acinetobacter baumannii is a leading pathogen responsible for nosocomial infections. The emergence of carbapenem-resistant A. baumannii (CRAB) has left few effective antibiotics for clinicians to use. To investigate the temporal evolutionary relationships among CRAB strains, we collected 248 CRAB isolates from a Chinese burns institute over 3 years. The prevalence of the OXA-23 gene was detecte...

Small-scale fisheries are an important source of food and livelihoods to coastal communities around the world. Understanding the seasonality of fisheries catch and composition is crucial to fisheries management, particularly in the context of changing environmental and socioeconomic conditions. While seasonal variability directly impacts the lives of fishers, most fisheries studies focus on lon...
