-This study evaluated the effect of feed supplementation (at doses of 0, 50, 100, 150, and 200 mg/kg) with SALUTO ® , a microencapsulated blend of essential oils including carvacrol, cinnamaldehyde, 1,8-cineol, and pepper oleoresin, in Nile tilapia (Oreochromis niloticus) broodstock on reproductive and growth parameters during the initial phase of rearing. The growth parameters, somatic indexes and gonadal and hepatic parameters were analyzed. Quantitative parameters of growth, ovary fat and crude protein were not affected by supplementation of the additive. However, an increase in crude protein in the female liver was observed in correlation with increased essential oil levels. The female hepatosomatic index was also correlated with supplementation of essential oils. Feeding Nile tilapia broodstock diets containing an essential oil compound (SALUTO ® ) affects only the females, promoting an increase in liver protein inclusion and hepatosomatic index without impairing performance.

The objective of this study was to evaluate the effect of copper-contaminated water on sperm motility, fertilization, and embryonic and larval development of silver catfish (Rhamdia quelen). A randomized experimental design with five treatments and four replicates was used. Two experiments were carried out: (1) controlled fertilization was performed under different levels of copper contamination and egg hatching was performed in clean water; and (2) copper-contaminated water was used for both fertilization and hatching assays. The time of sperm motility and sperm motility rates linearly decreased with increasing copper concentration in the water. Fertilization and hatching rates were also affected when the concentrations of copper in the water were above 0.0979 mg Cu +2 L -1 and 0.0331 mg Cu +2 L -1 , respectively. Gamete exposure to levels between 15 mg Cu +2 L -1 and 60 mg Cu +2 L -1 for short periods of time negatively affected sperm motility, oocyte fertilization, and egg hatching rates. In addition, when gametes and embryos were exposed at levels above 0.03 mg Cu +2 L -1 during long periods of time, egg hatching rates were reduced, and at levels between 0.05 mg Cu +2 L -1 and 0.20 mg Cu +2 L -1 the number of abnormal larvae increased.

ResumoO objetivo deste estudo foi avaliar o efeito da água contaminada de cobre na motilidade espermática, fertilização e desenvolvimento embrionário e larval de jundiá (Rhamdia quelen). O delineamento experimental foi inteiramente casualizado, com cinco tratamentos e quatro repetições. Dois ensaios foram conduzidos: (1) a fertilização controlada foi realizada com diferentes níveis de água contaminada com cobre e a incubação do ovo realizada em água limpa; e (2) a contaminação da água foi utilizada tanto na fertilização e quanto na incubação dos ovos. O tempo de motilidade de espermatozóides e as taxas de motilidade do esperma foram reduzidas com o aumento da concentração de cobre na água. As taxas de fertilização e eclosão também foram afetados quando as concentrações de cobre na água

South American fish species suitable for aquaponics: a review

et al. 2021

View full text Add to dashboard Cite

Tilapia and catfish are the most popular fish species in aquaponics. However, they are not well-accepted in all markets, and finding alternative species is important in order to increase the variety of food products and meet market demands. South America has several potential fish species for aquaponics systems. Encouraging the implementation of integrated aquaculture systems by providing information about the production of South American species can help to increase the supply of high-quality food and aquaculture diversification. Thus, data for five South American fish species with potential for aquaponics were compared with existing data for the main traditional warm water species in this system, tilapia and catfish. Moreover, the degree of suitability of the novel species for these systems in terms of zootechnical performance, tolerance to water quality and nutritional composition of fish flesh were discussed. The South American species considered were jundia or silver catfish (Rhamdia quelen), yellowtail lambari (Astyanax lacustris), pacu (Piaractus mesopotamicus), tambaqui (Colossoma macropomum) and snook (Centropomus spp.). Their description and the tabular comparison with the most traditional aquaponic-cultured species show they are suited for this production system. How suitable they are will depend on the system design, as well as the regional characteristics of the market where they will be produced.
