“…In addition, microorganisms can synthesize new fatty acids, elongating and desaturating the carbon chain (Ekasari et al, 2010). The significant presence of PUFA n-3 and n-6 in the biofloc, such as α-linolenic (C 18:3 n-3), can be elongated and desaturated to produce EPA and DHA, however, the process occurs in a low percentage (Suárez-Mahecha et al, 2002). In the present study, this fatty acid was not found with significant amounts in fish reared in BFT.…”

Tilapia is a species with great growth potential. Its production comes from a semi-intensive system, such as earthen ponds (EP). Recently, biofloc technology (BFT) appears as an option to intensify fish production. The objective of this work was to compare the organosomatic indices, biochemical parameters, and chemical composition of tilapia reared in EP and BFT. Fish were grown for 150 days, with an initial weight of ≅ 2 g and a final weight of ≅ 780 g. Thereafter, tissues and organs were collected to determine organosomatic indices and analyze biochemical parameters, fatty acid, and proximate composition. The carcass yield was higher for tilapia reared in EP than BFT. The production system did not affect the fish fillet yield. The other organosomatic parameters were higher for tilapia reared in BFT. Tilapia reared in EP showed higher content of crude protein and lipids in the fillet. In both production systems, there was no difference in the body lipid profile. Fish in BFT showed a higher concentration of glucose and ammonia in the muscle and amino acids in the liver. Fish reared in EP showed a higher concentration of lactate in the liver compared to those in BFT. In conclusion, the production system alters the metabolism of fish. The biofloc has a considerable amount of fatty acids, which can be considered in the formulation of diets for tilapia in this system.

“…Species of Brycon are used in commercial production and fi sh farming in Brazil (Wasko, 2005;Ninhaus-Silveira et al, 2006). The Bryconids have several advantages for fi sh farming, including their omnivorous feeding habits and their adaptation to low levels of oxygen (Suarez-Mahecha, 2002). There is a growing search for Brycon spp.…”

Conservation of Brycon orbignyanus natural populations and stocks for their reproductive, genetic, environmental sustainability: A model for threatened species of extinction. Cien. Inv. Agr. 36(2):191-208.Several ecological and climatic factors, especially those related to human activities, have been contributing to the disappearance of natural populations of piracanjuba (Brycon orbignyanus).Due to the importance of these fi sh to the ecosystems in which they are located and their qualities of fast growth and ability to adapt to controlled environments, producers have expressed increased interest in recent years in using this species, with particular aims of increasing production, and participation in conservation programs. In this study, strategies for the sustainable management of B. orbignyanus are idealized and discussed, with the goals of perfecting the reproductive, genetic, environmental and sanitary management of this species and suggestions for improving monitoring stocks maintained in captivity and natural populations. These strategies can be used as models for other migratory species threatened with extinction.

“…Among the main methods of evaluating freshness, sensorial, physicochemical, and microbiological methods stand out (de Paiva Soares & Gonçalves, 2012). Another characteristic of fundamental importance is firmness, a significant factor for evaluating fish meat quality and is directly related to its freshness (Suárez-Mahecha et al, 2007). Amaral and Freitas (2013) also state that firmness plays a fundamental role in the consumers' acceptance of meat protein.…”

The present study aimed to characterize the disaggregated fillets and determine the optimal quality parameters used in the pre‐slaughter management of Nile tilapia in the processing industries. The study was carried out in three stages: the first characterized the disaggregated fillet, the second determined the influence of season on the incidence of disaggregated fillets, and the third developed a desirability function to reduce the incidence of disaggregated fillets in the fish slaughter industry. It is believed that the disaggregated fillets are similar to PSE meat, and the influence of the season on their incidence was found in this study; that is, the summer influences the pallor of the tilapia fillet (summer: standard L* = 53.17 ± 0.43 and pH 6.22 ± 0.03; disaggregated L* = 57.54 ± 0.65 and pH = 6.14 ± 0.03 ‐ winter: standard L* = 41.53 ± 0.48 and pH 6.31 ± 0.02; disaggregated L* = 49.07 ± 0.61 and pH = 6.01 ± 0.04), as well as chicken and pork meats, whose values are determined by the L* color parameter and the pH, inversely proportional greatnesses. The incidence of disaggregated fillets is closely related to the management that precedes slaughter, so a desirability function was created to determine optimal values for quality standards of operations immediately before the slaughter of the animal. Novelty impact statement Characterizing Nile tilapia fillets as meats PSE according to the summer and winter seasons. Standardized pH and L* parameter values as determinants for PSE meats in Nile tilapia. Antemortem stress and temperatures influenced the determination of the disaggregated fillets.
