Betancor M, Sprague M, Ortega A, de la Gándara F, Tocher D, Ruth R, Perkins E & Mourente G (2020) Central and peripheral clocks in Atlantic bluefin tuna (Thunnus thynnus, L.): Daily rhythmicity of hepatic lipid metabolism and digestive genes. Aquaculture, 523, Art. No.: 735220. https://doi.org/10.1016/j.aquaculture.2020.735220 See

Atlantic bluefin tuna (ABT; Thunnus thynnus) is a highly regarded and consumed species, but farming is still in its infancy. Currently, nothing is known about the presence of circadian rhythmicity at central or peripheral tissues, or if there are daily rhythms in expression of genes involved in lipid metabolism. In order to elucidate clock gene regulation of genes of lipid metabolism in ABT, six clock genes (bmal1, clock, cry1, cry2, per1 and per2) were sequenced and 24 h expression of these ...

Jin M, Zhu T, Tocher D, Luo J, Shen Y, Li X, Pan T, Yuan Y, Betancor M, Jiao L, Sun P & Zhou Q (2020) Dietary fenofibrate attenuated high-fat-diet-induced lipid accumulation and inflammation response partly through regulation of pparα and sirt1 in juvenile black seabream (Acanthopagrus schlegelii). Developmental and Comparative Immunology. See

An 8-week feeding trail was conducted in Acanthopagrus schlegelii with an initial body weight of 8.34±0.01g. Three isonitrogenous diets were formulated, (1) Control: medium-fat diet (12%); (2) HFD: high-fat diet (18%); (3) HFD+FF: high-fat diet with fenofibrate (0.15%). Liver histological analysis revealed that, compared to HFD, vacuolar fat drops were smaller and fewer in fish fed fenofibrate. Expression of lipid catabolism regulator peroxisome proliferator-activated receptor alpha (pparα) w...

Luo J, Zhu T, Wang X, Chen X, Yuan Y, Jin M, Betancor M, Tocher D & Zhou Q (2020) Toxicological mechanism of excessive copper supplementation: Effects on coloration, copper bioaccumulation and oxidation resistance in mud crab Scylla paramamosain. Journal of Hazardous Materials. See

Copper is a widespread pollutant in marine environments, and marine animals can ingest large amounts of copper through the food chain. Here, an 8-week feeding trial was designed to investigate the effects of different dietary copper levels on coloration, copper bioaccumulation, stress response and oxidation resistance of juvenile mud crab Scylla paramamosain. The results indicated that crabs fed the diet with 162 mg/kg copper exhibited a dark-blue carapace and hemolymph. The accumulation of c...

Ramirez-Paredes JG, Larsson P, Thompson KD, Penman DJ, Busse H, Ohrman C, Sjodin A, Soto E, Richards RH, Adams A & Colquhoun DJ (2020) Reclassification of Francisella noatunensis subsp. orientalis Ottem et al. 2009 as Francisella orientalis sp. nov., Francisella noatunensis subsp. chilensis subsp. nov. and emended description of Francisella noatunensis. International Journal of Systematic and E... See

Francisella noatunensis is a fastidious facultative intracellular bacterial pathogen that causes ‘piscine francisellosis’, a serious disease affecting both marine and fresh water farmed and wild fish worldwide. Currently two F. noatunensis subspecies are recognized, i.e. F. noatunensis subsp. noatunensis and F. noatunensis subsp. orientalis . In the present study, the taxonomy of F. noatunensis was revisited using a polyphasic approach, including whole genome derived parameters such as digita...

Barillé L, Bris AL, Goulletquer P, Thomas Y, Glize P, Kane F, Falconer L, Guillotreau P, Trouillet B, Palmer S & Gernez P (2020) Biological, socio-economic, and administrative opportunities and challenges to moving aquaculture offshore for small French oyster-farming companies. Aquaculture, 521, Art. No.: 735045. https://doi.org/10.1016/j.aquaculture.2020.735045 See

Oyster production has historically taken place in intertidal zones, and shellfish farms already occupy large extents of the French intertidal space. The expansion of French shellfish aquaculture within intertidal areas is therefore spatially limited, and moving production to the subtidal offshore environment is considered to be a possible solution to this problem. Finding new sites along the French Atlantic coast was studied here from the perspective of small oyster companies run by young far...
