“…Wild populations of native fishes are mainly affected by overfishing, anthropogenic alterations of habitat and the introduction of exotic species (Martínez-Cárdenas et al 2014). Therefore, diversification and experimentation with tropical native fish species are essential to create an aquaculture industry to protect the integrity of wild fish communities and contribute to its safety through repopulation protocols.…”

Background: Native fish species are a developing alternative for sustainable aquaculture worldwide and in Mexico, the southern region is leading the efforts in freshwater species. Objective: To assess the effect of different stocking densities on the productive performance of native fish juveniles of blackstripe cichlid (Vieja fenestrata). Methodology: A one-factor randomized experimental design was used, evaluating in triplicate four stocking densities, 0.5 (L), 2 (M), 4 (H) and 6 (S) juvenile L-1. The experiment lasted 30 days. Wet weight and total length were registered every 15 days and growth performance indices were obtained. Results: Growth and survival were superior (P<0.05) for densities L and M. However, the M density showed a higher (P<0.05) growth rate, weight gain, and condition factor. Implications: The stocking density showed an apparent effect on the growth and survival of juveniles of the blackstripe cichlid, with the M density showing the best results; however, a cost-benefit assessment is required before starting production of this tropical native species. Conclusion: Our results suggest that a territorial and/or food competition was probably responsible for the survival and growth obtained. Although more studies are required, it appears that Vieja fenestrata showed the typical patrons of behaviour of another most famous cichlids, as Nile tilapia, with high levels of aggression that depend on stoking density.

This study undertakes the characterization of digestive proteases in the juvenile green cichlid, Cichlasoma beani. The results obtained showed a higher activity of alkaline proteases (0.14 ± 0.01 U mg protein −1 ) compared to acid proteases (0.07 ± 0.01 U mg protein −1 ) in this species. The optimum temperature of the alkaline proteases was 65 • C and these enzymes were more thermostable to temperature changes than the acid proteases, characterized by an optimal temperature of 55 • C. The pH optimum was 2 for acid proteases, and 11 for alkaline proteases, which were also more stable to changes in pH between 8 and 10. The use of specific inhibitors showed an acid protease inhibition of 88% with pepstatin A as inhibitor. In the zymogram SDS-PAGE analysis of alkaline proteases, five active fractions were revealed, indicating the presence of serine proteases. These results confirm that both alkaline and acid proteases are involved in the digestion of C. beani, and suggest that this species is omnivorous with carnivorous tendencies. The present study contributes to our knowledge about the digestive physiology of C. beani, and can be applied towards improved understanding of the kinds of protein sources that could be used in the development of inerts diets.
