“…The results are similar to those reported by Mai et al (1980) for six freshwater species from the United States, except for lysine content which was higher in the pacu. High lysine, 11.4 g/16 g of N, was also found for curimbat6 (Prochilodus scrota) by Maia et al (1983) and for tilapia (Tilapia nilotica) (10.6 g/16 g of N) by Khalil et al (1980). By comparing the essential amino acids of pacu with the National Research Council (NCR, Results of the nitrogen balance and PER determined on casein, full-fat, and defatted fillet from pacu are given in Table IV.…”

“…Similar extraction (93%) was obtained by Awad et al (1969) from the freshwater fish Coregonus clupeiformis. Khalil et al (1980) found 66.7 % for the myofibrillar proteins and 24.8 % for the sarcoplasmic proteins in T. nilotica. Moorjani et al (1962) found different values for extractable proteins in four species of freshwater fish in India, i.e., total extractable protein of 90.7,77.8,90.0, and 86% with sarcoplasmic protein contents corresponding to 29.0, 22.0, 35.0, and 35.7 % , respectively.…”

The edible portion (fillet) of pacu (Colossoma mitrei), a freshwater fish from the south of Brazil, was composed of 67.7% water, 13% protein, 17.2% total lipids, and 1.3% minerals. The muscle proteins were composed of 64.3 % myofibrillar, 25 % sarcoplasmic, and 8 % stroma proteins. Simple polyacrylamide gel electrophoresis revealed six protein bands in the sarcoplasmic fraction; SDS-polyacrylamide gel electrophoresis revealed eight protein structural units with molecular weights ranging from 4000 to 149 000. Total protein nutritive value was similar to that of casein in terms of PER and growthpromoting capacity. Full-fat fillet protein did not differ from casein (p = 0.05) with respect to apparent digestibility and net protein utilization but was inferior to casein in the apparent biological value. On the other hand, defatted fillet protein was inferior to casein (p = 0.05) in all of the three indices calculated.Pacu (Colossoma mitrei, Berg 1895) is a freshwater fish of the order Cypriniform, suborder Characoidei, and family Myleinae.

The contribution of fisheries and aquaculture to the global protein supply

2022

View full text Add to dashboard Cite

The contribution of aquatic animal protein to the global, animal-source protein supply and the relative importance of aquaculture to capture fisheries in supplying this protein is relevant in assessments and decisions related to the future of aquatic food production and its security. Meat of terrestrial animals, milk, and eggs resulted in 76,966 Kt crude protein compared with 13,950 Kt or 15.3% from aquatic animals in 2018.While aquaculture produced a greater tonnage of aquatic animals, capture fisheries resulted in 7,135 Kt crude protein while aquaculture yielded 6,815 Kt. Capture fisheries production has not increased in the past two decades, and aquaculture production must increase to assure the growing demand for fisheries products by a larger and more affluent population. We estimated based on status quo consumption, that aquaculture production would need to increase from 82,087 Kt in 2018 to 129,000 Kt by 2050 to meet the demand of the greater population. About two-thirds of finfish and crustacean production by aquaculture is feed-based, and feeds for these species include fishmeal and fish oil as ingredients. Aquaculture feeds require a major portion of the global supply of fishmeal and fish oil. An estimated 71.0% of fishmeal and 73.9% of fish oil are made from the catch with the rest coming from aquatic animal processing waste. The catch of small, pelagic fish from the ocean is not predicted to increase in the future. Aquaculture should reduce its fishmeal and oil use to lessen its dependency on small wild fish important to the integrity of marine food webs and food security for the poor in many coastal areas. Fishmeal and fish oil shortages for use in aquaculture feed will result in a limit on production in the future if goals to lessen their use in feeds are not met.
