“…The proximate composition, including moisture, protein, lipids Ahmmed et al (2020) and ash contents, was determined as described by AOAC (2003) and Ahmmed et al (2021). Briefly, 36 hatchery and wild crabs of different sizes, including three males and three females, were randomly selected from each pond, euthanized on ice for two hours, then washed in chilled water.…”

This paper reports the comparative growth, nutritional performance, and morphometric variation between wild and hatchery-reared juvenile mud crabs (Scylla olivacea) in earthen ponds. The crabs were fed daily with boiled tilapia paste at a feeding rate of 5-8% body weight for the first two weeks, followed by feeding with chopped eviscerated tilapia until termination of the experiment. Selected phenotypic trains, including carapace width (CW), carapace length (CL) and abdominal width (AW), were measured weekly. The protein content of the muscle (21.13%), gill (13.51%) and egg (43.28%) were significantly higher in the hatchery-sourced compared to wild female crabs (muscle ¼ 19.15%; gill ¼ 10.09%; egg ¼ 38.15%). Likewise, the hatchery sourced crabs exhibited higher lipid content in the muscle (2.45-2.51%) and eggs (7.51%) compared to the wild counterparts (muscle ¼ 1.45-1.47%; egg ¼ 6.15%). These findings suggested a superior nutritional quality of the hatchery-reared compared to the wild-sourced crabs. Although some selected phenotypic traits did not vary among the wild and hatchery-reared crabs (p < 0.05), their survival rates varied significantly depending on the stocking density (p < 0.05). Overall, the findings suggest that the growth characteristics of the hatchery produced and wild-sourced crab were similar, which will help to remove the misconception among the crab farmers about the hatchery seeds and promote diversification of the crab production system for long-term sustainability.

“…Therefore, SLO should be consumed with caution. There are some alternatives such as mono-alkylglycerols (chimyl alcohol, batyl J o u r n a l P r e -p r o o f alcohol or selachyl alcohol) (47) or marine food supplements (48) which can be used to enrich endogenous plasmalogens. However, the currently available mono-alkylglycerols are not approved for human consumption and the potential of marine food supplements in modulating endogenous plasmalogens is still in question.…”

“…Fish processing generates substantial amounts of co-products, such as fish frame, trimmings, head, skin, scales, roe (gonad), and viscera [ 4 ] that are typically used either as fish meal, biofertilizer, for the production of oil, or are discarded. Some of these co-products, such as head, roe, skin, and gonad are increasingly recognized for their phospholipid content, which comprises substantial amounts of bioactive components such as EPA and DHA [ 5 , 6 , 7 , 8 ]. Previous literature has demonstrated the health benefits of n-3 phospholipids, specifically, EPA, DPA, and DHA, that can enhance brain health and create a positive outcome for the prevention of neurodegenerative disorders, cardiovascular disease, non-alcoholic fatty liver disease, diabetes, and some cancers [ 2 ].…”

Processing of hoki, a commercially important fish species, generates substantial quantities of co-products, including male gonad, which contains valuable lipids, such as phospholipids, that could be recovered and utilised. Hoki fish male gonads (HMG) were subjected to pulsed electric fields (PEF) treatment at varying field strengths (0.625, 1.25, and 1.875 kV/cm) and frequencies (25, 50, and 100 Hz), at a fixed pulse width of 20 μs. The total lipid was extracted using an ethanol-hexane-based (ETHEX) extraction method, and the phospholipid and fatty acid compositions were determined using 31P NMR and GC-FID, respectively. The total lipid yield was increased from 4.1% to 6.7% by a relatively mild PEF pre-treatment at a field strength of 1.25 kV/cm and frequency of 50 Hz. A higher amount of EPA (8.2%), DPA (2.7%), and DHA (35.7%) were obtained by that treatment, compared to both un-heated (EPA: 8%; DPA: 2.5%; DHA: 35.2%) and heat-treated controls (EPA: 7.9%; DPA: 2.5%; DHA: 34%). No significant changes to the content of the major phospholipids were observed. PEF pre-treatment under mild conditions has potential for improving the total lipid yield extracted from fish male gonad.
