The use of preserved copepods in sea bream small-scale culture: biometric, biochemical and molecular implications

Considering the well‐known problems arising from the use of rotifers and Artemia as live prey in larval rearing in terms of fatty acid deficiencies, the aim of this study was to evaluate a partial or complete replacement of traditional live prey with preserved copepods during the larviculture of gilthead sea bream (Sparus aurata). Sea bream larvae were randomly divided into 4 experimental groups in triplicates: group A larvae (control) fed rotifers followed by Artemia nauplii; group B fed a combined diet (50%) of rotifers–Artemia and preserved copepods; group C fed rotifers followed by preserved copepods; and group D fed preserved copepods solely. Survival and biometric data were analysed together with major molecular biomarkers involved in growth, lipid metabolism and appetite. Moreover, fatty acid content of prey and larvae was also analysed. At the end of 40 days treatment, a stress test, on the remaining larvae, was performed to evaluate the effects of different diets on stress response. Data obtained evidenced a positive effect of cofeeding preserved copepods during sea bream larviculture. Higher survival and growth were achieved in group B (fed combined diet) larvae respect to control. In addition, preserved copepods cofeeding was able to positively modulate genes involved in fish growth, lipid metabolism, stress response and appetite regulation.

Implications of holdfast availability and patchiness on juvenile seahorse (Hippocampus reidi) condition and welfare: Simulations in captivity

Seahorses (Genus Hippocampus; Family Syngnathidae) are iconic fish characterised by tails with prehensile capabilities, which develop after the transition from planktonic to benthonic lifestyle. As a result, seahorses remain attached to vegetal structures or other elements most of the time, both in the wild and under rearing conditions. In the present simulation study, we assessed the effect of artificial holdfast structures on the welfare of Hippocampus reidi juveniles maintained for 30 days under culture conditions. For that, both availability and patchiness of holdfast elements were considered, simulating different levels of habitat complexity. The results attained on the bioindicators assessed (survival, growth, distribution and final colouration) suggest that the viability of juveniles deprived of holdfast elements was not hampered. However, the differences observed in the final colouration of juveniles would be the result of superior welfare condition in fishes maintained in the presence of attachment structures. In addition, lower aggregation of juveniles was promoted by low complexity in simulated habitats. The results seem to indicate that habitat complexity in the wild does not affect juvenile's viability but provides better conditions for shelter and fast access to prey. However, further investigations are needed to evaluate potential detrimental effects of holdfast unavailability as a potential physiological stressor factor.

This field study investigates the morphological indices (condition index, hepatosomatic index) and biochemical (catalase (CAT), glutathione S-transferase (GST), acetylcholinesterase (AChE), metallothionein (MT), lipid peroxidation) parameters in liver, gills and kidney of common sole (Solea solea) originating from different sites of the Tunisian coast area impacted by different anthropogenic activities. Differences among sites and tissues for AChE, GST, CAT, MT and TBARS were found and possibly related to known sources of domestic and industrial discharges in the studied sites. Liver, gills and kidney CAT, liver and kidney MT and brain AChE were key biomarkers to discriminate fish of different sites. So, we suggest using these biomarkers in future biomonitoring.
