“…In addition, those authors used a diet with 35–55 g/kg of fish meal, which could improve growth performance. In a 240‐day study with pacú weighting 1.3 ± 0.26 g, dos Santos et al () found that cultivation at 24°C caused lower final weight, SGR and feed conversion ratio than at 28°C or 32°C.…”

Dietary β‐carotene improves growth performance and antioxidant status of juvenilePiaractus mesopotamicus

This study was conducted to investigate the effects of dietary synthetic β‐carotene on growth performance, haematological and immunological parameters, energy reserves and antioxidant status of juvenile fish Piaractus mesopotamicus. Two hundred and ten fish (12.24 ± 2.98 g) were fed with a control extruded feed (CEF) and the same diet supplemented with β‐carotene (BEF) for 90 days. A higher weight gain and specific growth rate were found in fish fed BEF in comparison with those fed CEF. In addition, BEF‐fed fish showed lower liver somatic index and a higher percentage of eosinophils. No statistical differences were found in energy reserves, except for plasma triglycerides which decreased in fish fed with BEF. Regarding oxidative stress markers, decreased activities of antioxidant enzymes were found in intestine and gills of BEF‐fed fish (SOD and GST, respectively). In the liver, both LPO levels and CAT activity decreased in fish fed with BEF. Additionally, lower brain LPO levels without changes in the antioxidant enzymes were observed in BEF‐fed fish. The inclusion of dietary synthetic β‐carotene improved growth and antioxidant status, and had a plasma triglyceride‐lowering effect in juvenile P. mesopotamicus.

“…Perhaps it is that grass carp is always in the state of flowing water to stimulate exercise under the high‐density IPRS mode, so that the muscles of the whole body have been exercised, and such organizational structure changes will appear. Consistently, Dos Santos et al (2017) found that moderate exercise reduced the diameter of Piaractus mesopotamicus muscle fibers, which enabled it to have higher metabolic activity and recruit fibers for swimming activities. Furthermore, our study found that IPRS can improve the protein content of muscle and decrease of fat content in muscle may also be because of the IPRS mode.…”

In‐pond raceway systems (IPRS) are a high‐density ecological green pond aquaculture mode, which has developed rapidly in China in recent years. This study evaluated the flesh quality and physiological response of grass carp under the IPRS mode. Compared with the traditional earthen pond (EP) mode, the grass carp hepatosomatic index and viscerosomatic index under the IPRS mode are significantly (p < 0.05) lower. And the water holding capacity of grass carp muscles were significantly (p < 0.05) improved. Compared with EP mode, grass carp muscles under the IPRS mode have more crude protein content and less crude fat content, and have higher muscle fiber density and smaller muscle fiber diameter. In the IPRS mode, the total amount of essential amino acids (∑EAA) in grass carp muscle increased significantly (p < 0.05), and the content of savory amino acids increased significantly (p < 0.05). In addition, the content of eicosapentaenoic acid and docosahexaenoic acid in the muscle fatty acids of IPRS grass carp was also significantly (p < 0.05) higher than EP mode. At the same time, in order to cope with the high‐density culture mode of IPRS, the activity of catalase and superoxide dismutase in grass carp muscle was significantly (p < 0.05) increased, and the alanine aminotransferase in serum, aspartate aminotransferase, as well as other biochemical indexes, increased significantly (p < 0.05). In the IPRS mode, the mass‐specific lamellae respiratory area of the gill increased significantly (p < 0.05), and the volume of the interlaminar cell mass decreased significantly (p < 0.05) to increase oxygen intake. Taken together, our results show that grass carp will produce relevant physiological response to cope with the IPRS high‐density culture environment, while their flesh yield, flesh quality, and nutritional value is improved.

“…They were determined the mortality rate, specific growth rate (SGR) and feed conversion rate (FCR) according to Santos et al. (2017). Viscerosomatic (VSI) and hepatosomatic (HSI) indexes were also calculated as percentage of viscera and liver weight in relation to fish weight.…”

This study aimed to evaluate the probiotic additive on tilapia growth by establishing growth curves, as well as assessing the morphology of the muscular and ventral subcutaneous adipose tissues, carcass characteristics and gene expression that controls growth. Fingerlings of 5 g were grown in a recirculating aquaculture system consisting of 15 water tanks (0.25 m3) at 80 fish/m3. Fish were fed three times daily with the same feed, using additive with Bacillus subtilis, Bifidobacterium bifidum, Enterococcus faecium, Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus lactis, Lactobacillus plantarum and Pediococcus acidilactici (1.0 × 109 CFU/g). They were assessed levels of 0.1% and 0.2% of additive probiotic homogenized in 2% soy oil and sprinkled over the feed. Exponential models were fit to compare growth rates, weighing samples at days 0, 30, 60 and 90 of cultivation. The probiotic mixture used in this study as feed additive may be diffused in aquaculture in order to increase productivity, as demonstrated by feed conversion rate, final weight and growth (13%–37% for 0.1% and 0.2% of additive level respectively). Growth stimulation occurred by white muscle fibre hypertrophy, accompanied by inhibition of MyoD and myostatin, gene expression and increase in the number of intestinal villi, ensuring greater absorption and utilization of nutrients provided in the diet.
