Hexabromocyclododecane in consumer fish from South China: Implications for human exposure via dietary intake
Levels of hexabromocyclododecane (HBCD) were determined in 12 consumer fish species from South China. The concentrations of the sum of HBCD diastereoisomers (ΣHBCD) ranged from nondetectable to 194 pg/g wet weight, with a detectable frequency of 70%. This was at the low end of the concentration range globally observed. Carnivorous fish species contained higher HBCD concentrations than herbivorous ...

Use of sea water and hydraulic conditions. Potential cause of Mortality by Metals and Hydrogen Sulfide in Recirculation Fisheries
The traditional conception in Chile of the toxic effect of metals on cultured fish tends to weigh heavily on incoming freshwater in open flow fish farms as the major responsible for mortality in early stages of development in salmon species. This approach is mainly based on two conditions that refer to freshwater quality in Chile, and to the dilutive effect of recirculation fish stocks when a ...

A functional hydrolysate adds value to feeds for omnivorous fish species
Omnivorous fish species are known to be less demanding in terms of nutritional and palatability requirements and yet dietary hydrolysate supplementation greatly improved production yields and margins. Several biological benefits are associated with protein hydrolysates and they have been used in finfish larval and juvenile diets for several decades now, mainly due to their high palatability and ...
