“…Several types of research on incorporating essential nutrients in fish feeds is a new way to food enrichment for human consumption. It is known that the body lipid profile of fish can be adjusted according to diet and inclusion of omega‐3 source additives, such as docosahexaenoic acid (DHA) in fish feed, being an alternative to increase the levels of this fatty acid in the body (Ayisi, Zhao, & Rupia, ; Lenihan‐Geels, Bishop, & Ferguson, ; Martins et al, ; Qiu et al, ).…”

The objective of this study was to evaluate growth, body chemical composition and lipid profile of Nile tilapia juvenile fed with Schizochytrium sp. Two hundred and forty Nile tilapia (Oreochromis niloticus) juvenile (1.33 ± 0.11 g) were distributed in 20 aquariums, at the density of 12 fish per aquarium. The juvenile were fed with five levels of Schizochytrium sp.: Control (0 g/kg of Schizochytrium sp. in feed); AS10 (10 g/kg of Schizochytrium sp. in feed); AS20 (20 g/kg of Schizochytrium sp. in feed); AS30 (30 g/kg of Schizochytrium sp. in feed) and AS40 (40 g/kg of Schizochytrium sp. in feed). The inclusion of Schizochytrium sp. increase the body weight, weight gain, final biomass and biomass gain of tilapia juvenile. The body crude protein of tilapia was increased after addition of microalgae. Juvenile lipid profile also was influenced when fed with 40 g of Schizochytrium sp. per kg and have it levels of omega‐3 and docosahexaenoic acid (DHA) increased, and omega 6:3 ratio decreased. Tilapia juvenile fed with Schizochytrium sp. per kg have better growth, omega‐3 and DHA levels rising in the body, being a considerable source of fatty acids for human nutrition. Levels above 20 g of Schizochytrium sp. per kg in the feed favour the increase of protein in Nile tilapia body.

“…Presently people are more sensitive to healthy eating than in the past (Oriakpono et al, 2011). People prefer white meat like fish over to red meat due to its high nutritional contents (Mahboob et al, 1996;Ayisi et al, 2017). Aquaculture practices are considered today as one of the most promising sources of animal protein.…”

Study on assessment of proximate composition and meat quality of fresh and stored Clarias gariepinus and Cyprinus carpio

et al. 2019

The organoleptic evaluation and proximate analysis of Clarias gariepinus and Cyprinus carpio were determined in fresh fish and when refrigerated at two different temperatures (-21 °C and 4 °C) for a period of six weeks. A panel of twelve trained judges evaluated the color (live), texture, softness and flavor of fish meat after two minutes’ steam cooking. Average score revealed a general decline in organoleptic properties such as color, texture, freshness, and taste of C. gariepinus and C. carpio stored at two temperatures compared to the fresh fish. Proximate analysis revealed a more decrease in crude protein and lipid contents and increase in ash content in C. gariepinus and C. carpio at the two storage temperatures compared to the fresh fish muscle. Moisture content decreased in the fish muscle samples of both the fish species stored at -21 °C but increased in the 4 °C stored samples. pH of fish was found to increase in the two stored temperatures. There were significant differences (P<0.05) in the organoleptic and proximate composition of the ice stored and fresh C. gariepinus and C. carpio, the same temperature and between the two different temperatures. The quality of fish muscle stored at 4 °C deteriorated faster than that of the -21 °C. Thus, storage temperature and duration have adverse effects on the nutritional quality of fish meat.

“…Therefore, fish quality can be improved through the use of dietary lipid sources that increase fish EPA and DHA contents. The source of dietary lipids can also affect growth, survival, feed utilization, digestive capacity, immune function, haemato‐biochemical status, lipid metabolism and fat deposition (Ayisi, Zhao, & Rupia, ; Bami, Kamarudin, Saad, Arshad, & Ebrahimi, ; Chen et al., ; Li, Liang et al., ; Subhadra, Lochmann, Rawles, & Chen, ; Sun et al., ; Zhang et al., ).…”

This study investigated the effects of dietary lipid sources on juvenile blunt snout bream, Megalobrama amblycephala. Juvenile blunt snout bream (14.40 ± 0.01 g) were fed diets containing 75 g/kg of fish oil (FO), linseed oil (LO), soybean oil, coconut oil (CO), rapeseed oil or beef tallow (BT) for 9 weeks. Survival rates, final weight, weight gain, feed efficiency ratio and feed intake remained unchanged. Viscerosomatic ratio, hepatosomatic index and condition factor were highest in fish fed the CO diet (p < 0.05). Whole‐body lipid content decreased, whereas liver lipid content increased in fish fed CO and BT diets (p < 0.05). Eicosapentaenoic acid and docosahexaenoic acid in the muscle and liver increased in fish fed the FO and LO diets (p < 0.05). FO and LO diets increased plasma glucose (p < 0.05). Feeding CO diet increased hepatic fatty acid synthase (FAS) and acetyl‐CoA carboxylase expression, and FAS activity (p < 0.05). Both CO and BT diets increased hepatic carnitine palmitoyltransferase I (CPT I) and carnitine palmitoyltransferase II expression, and CPT I activity compared to the FO diet (p < 0.05). These results indicate that LO can be substituted for FO in juvenile blunt snout bream diets without negative effects.
