Ecosystem Impacts of the Landing Obligation for Unwanted Catch in Thermaikos Gulf (Greece)
ABSTRACT Discards by marine commercial fisheries have been an issue of major concern to the scientific community in recent years. We modeled the ecological and trophic consequences of a mandatory landing obligation (LO) regulated by the reformed Common Fisheries Policy [Regulation (EU) 1380/2013] on the Thermaikos Gulf ecosystem (northwestern Aegean ...

Measuring Peripheral Tissue DHA Turnover Using a Novel 13C Enrichment Technique
ABSTRACT Recently, through the use of compound‐specific isotope analysis (CSIA), our lab validated the utility of 13C enrichment (δ13C) of docosahexaenoic acid (DHA) by using a very high δ13C in a diet switch study by measuring brain, liver, and plasma DHA turnover and half‐lives via high‐precision gas chromatography combustion isotope ratio mass ...

Abstract Zooplanktonic organisms are considered a key link between different trophic levels. The ecosystem structure and dynamics are affected by changes in their population and phenology. In this work, the causes and timing of changes within the seasonal cycle of zooplankton biomass vertical distribution in oceanic waters of the Bay of Biscay were ...

Growth and reproduction of horse mackerel, Trachurus trachurus (carangidae). [PDF]
There is a broad knowledge of the growth and reproduction of Trachurus trachurus, although important gaps still exist. Horse mackerel are a long-lived species, reaching up to 40 years of age. They have isometric growth, although the alometric parameter b

Study on Phototaxis and Food‐Inducing Effects in Procambarus clarkii
As a globally significant freshwater aquaculture species, Procambarus clarkii has attracted considerable attention due to its economic value. Understanding its behavioral characteristics is crucial for improving aquaculture practices. This study systematically investigated the effects of different light conditions and feeding attractants on P.

ABSTRACT Major threats to marine species and ecosystems include overfishing, invasive species, pollution and climate change. The changing climate not only imposes direct threats through the impacts of severe marine heatwaves, cyclones and ocean acidification but also complicates fisheries and invasive species management by driving species range shifts.
