Abstract The Pacific oyster Crassostrea gigas is among the most frequently cultured aquaculture species worldwide. In bivalve aquaculture, some environmental factors may induce the production of Reactive Species of Oxygen (ROS) that besides causing injuries to several vital cellular components, may lead to inflammatory processes. Usually, antioxidant enzymes of bivalves defense systems have an important role in the diminution of harmful effects of ROS. However sometimes it is not enough to resto...

Probiotic influence on fish immune response and digestive capacity is extensively discussed in aquaculture. In this experiment, a feeding trial was carried out for 100 days to evaluate the cross-effects of probiotic supplementation and rearing temperature (17, 20 and 23°C) in juvenile seabass (Dicentrarchus labrax). The experimental diet was supplemented with a commercial probiotic blend (Biomin AquaStar Growout) at 3 g/kg diet (5.23 × 108 CFU/kg diet), and tested against a non-supplemented diet...

The sustainability of the Hetao Irrigation System, located in the water scarce upper Yellow River basin, is a priority considering the need for water saving, increased water productivity, and higher farmers’ incomes. The upgrading of basin irrigation, the main irrigation method, is essential and includes the adoption of precise land levelling, cut-off management, improved water distribution uniformity, and adequate irrigation scheduling. With this objective, the current study focuses on upgradin...

ABSTRACT The current study evaluated the microalgae replacement by dry macroalgae ( Ulva rigida ) in the reproductive success and biochemical composition of the Pacific oyster ( Crassostrea gigas ) during broodstock conditioning. Five nutritional regimes were tested: 100% macroalgae (diet 1), 50% macroalgae+50% microalgae (diet 2), 25% macroalgae+75% microalgae (diet 3) and 100% microalgae (diet 4). An unfed group was used as a negative control. The microalgae blend was composed of 33% Isochrysi...

The current study evaluated the effects of dietary seaweed supplementation in European seabass juveniles (Dicentrarchus labrax) subjected to rearing temperature and salinity oscillations, simulating natural variations in pond aquaculture conditions. Two experimental diets where formulated: a control diet (CTRL) with no supplementation and one supplemented with 7.5% seaweed mix (SW 2.5% Fucus sp., 2.5% Gracilaria sp. and 2.5% Ulva sp.). Seabass from both dietary groups (40.7 g initial body weight...

Effects of dietary seaweed supplementation on basal physiology and health biomarkers were assessed in meagre (Argyrosomus regius) subjected to bacterial infection, using Photobacterium damselae subsp. Piscicida (Phdp) as the etiologic agent. Three test diets were prepared by supplementing a basal control formulation (44 % protein, 16 % lipid, 22 kJ g−1 energy) with 0 % seaweed (control), 5 % Gracilaria sp. or 5 % Alaria sp. During the growth trial, 180 fish (39.70 ± 0.33 g) were daily fed for 69...

Abstract Dietary ion content is known to alter the acid-base balance in freshwater fish. The current study investigated the metabolic impact of acid-base disturbances produced by differences in dietary electrolyte balance (DEB) in the meagre ( Argyrosomus regius ), an euryhaline species. Changes in fish performance, gastric chyme characteristics, pH and ion concentrations in the bloodstream, digestive enzyme activities and metabolic rates were analyzed in meagre fed ad libitum two experimental d...

Summary Temperature modulates the metabolism in both fish and bacteria and therefore the effect of probiotic bacteria on its host may vary accordingly. The current study aim was to evaluate the effect of probiotic supplementation (Bacillus sp., Lactobacillus sp., Enterococcus sp., Pediococcus sp.) in juvenile seabass, Dicentrarchus labrax, when reared under different temperatures (17, 20 and 23°C). A control diet was tested against a probiotic-supplemented diet, with a concentration of 3 × 109 C...

Abstract This work aimed to appraise growth performance, digestive capacity and immune and stress responsiveness in European seabass ( Dicentrarchus labrax ) when fed diets supplemented with seaweeds. A control diet (without supplementation) was tested against 6 practical diets supplemented either with Gracilaria spp., Ulva spp., or Fucus spp., at 2.5 or 7.5% levels, plus an additional diet with a blend of the three seaweeds, each supplemented at 2.5% ( Mix ). Seabass juveniles (24.0 ± 6.3 g) we...
