Background The increasing demand for raw or undercooked fish products, supplied by both aquaculture and fisheries, raises concerns about the transmission risk to humans of zoonotic parasites. This has led current European Union (EU) Regulation No 1276/2011 amending Annex III (EC) 853/2004 mandating a freezing treatment such products. Zoonotic parasites, particularly anisakid larvae, have been w...

Market policies have profound implications for consumers as well as for the management of resources. One of the major concerns in fish trading is species mislabelling: the commercial name used does not correspond to the product, most often because the product is in fact a cheaper or a more easily available species. Substitution rates depend heavily on species, some often being sold mislabelled ...

acanthopagrus latus is one of the major commercially exploited species in the persian gulf. in recent years, it has gained importance as a candidate for aquaculture. haematological parameters of wild-caught specimens were studied during the pre-spawning period to determine if they are influenced by the sex of fish. blood samples were collected from 55 fish (30 female and 25 male) captured from ...

OBJECTIVE To investigate seasonal variations in tissue phosphorus (P) levels, P to protein ratio, and P to omega-3 fatty acid (ω3-FA) ratio in 2 species of fish that are commonly consumed in Lebanon. We aim to determine suitability for dietary management of renal patients. DESIGN AND SETTING Siganus rivulatus (rabbitfish) and Diplodus sargus (white seabream) were caught in traps off the coast...

Background: The egg yolk precursor protein vitellogenin (VTG) has proven to be a useful biomarker, used to identify organisms exposed to estrogenic compounds. Methods: We investigated variations in the VTG gene expression pattern and plasma sex steroid hormones concentrations in the yellowfin Seabream, Acanthopagrus latus, (A. latus) by various doses of bisphenol-A (BPA) exposure for 7 and 14 ...

Swimbladder inflation is a significant matter in intensive fish farming, since it related to larval survival rate and the morphological quality of individuals. In this work, we propose non-invasive acoustic technique using ultrasound monitor swimbladder development gilthead seabream (Sparus aurata) tanks. The fundamental hypothesis that, due high contrast gas, swimbladder’s process can be detec...

A spatially disaggregated, length-based, age-structured model for yellowfin tuna (Thunnus albacares) in the western and central Pacific Ocean is described. Catch, effort, length-frequency and tagging data stratified by quarter (for the period 1962−99), seven model regions and 16 fisheries are used in the analysis. The model structure includes quarterly recruitment in each region, 20 quarterly a...
