The fishery activities affect the lives of millions of people who live near the south of Caspian Sea, where the aquatic stocks have sophisticated ecological relationships. In this study, carbon and nitrogen stable isotope technique was applied as an ecological tool to interpret the fish catch values of different areas in relation to food chain. The average values of Captured bony fishes in six ...

Many fisheries in the world are data-moderate, with data types (e.g., total removals, abundance indices, and biological composition data) of varied quality limited time series or representative samples) available data. Integrated stock assessments useful tools for data-moderate as they can include all information, be updated due to availability more information over time, directly test inclusio...

The black-striped pipefish, Syngnathus abaster, is a species of the Syngnathidae family. This study provides data on the morphometric, meristic and genetic structuring of the Caspian Sea pipefish, Syngnathus abaster. Eight morphometric characteristics based on total length and five morphometric characteristics based on standard length were analyzed. A total of 50 specimens were collected in bra...

AIMS Enrolling children into several trials could increase recruitment and lead to quicker delivery of optimal care in paediatric intensive care units (PICU). We evaluated decisions taken by clinicians and parents in PICU on co-enrolment for two large pragmatic trials: the CATCH trial (CATheters in CHildren) comparing impregnated with standard central venous catheters (CVCs) for reducing bloods...

Several data-poor stock assessment methods have recently been proposed and applied to fisheries around the world. The Mauritanian pink spiny lobster fishery has a long history of boom bust dynamics, with large landings, collapse, years-long closures, all happening several times. In this study, we used catch, fishing efforts, length-frequency data (LFD) obtained from in its most recent period ac...
