“…This preference could be due to a better efficiency in the energetic balance (Portella et al, 1997;Atencio-García et al, 2003b), and was also registered for other planktivorous fish (Zaret, 1980;Mageed and Konsowa, 2002). In particular, larvae and juveniles of freshwater neotropical species, such as Brycon siebenthalae (Yamú), Prochilodus magdalenae (Bocachico), Piaractus mesopotamicus (Pacú), Colossoma macropomum (Tambaqui) and Prochilodus scrofa (Curimba) (Atencio-García et al, 2003a;Atencio-García et al, 2003b;Fregadolli, 1990;Pelli et al, 1996) have high selectivity toward cladocerans and copepods and an insignificant intake of rotifers and protozoa (Prieto Guevara and Atencio-García, 2008).…”

“…Although eggs and larvae can be produced in a massive way, one of the main constraints is the acquisition of large numbers of juveniles for stocking or fattening. To achieve success in aquaculture, it is necessary to consider the "critical period" (sensu Hjort, 1914) of the first feeding stages (Atencio-García et al, 2003a;Prieto Guevara et al, 2006) and understand how the environmental characteristics relate to the feeding habits of fish. In fact, the feeding and nutrition of fish post-larvae could represent a bottleneck that prevents expansion of the activity (Prieto Guevara and Atencio-García, 2008) as occurs with pejerrey.…”

Seasonality effects over the ecological aquaculture of the native zooplanktivorous fish from South America Odontesthes bonariensis

et al. 2017

Ecological aquaculture systems consider the natural and social environments in which they are situated in the search to contribute to environmental sustainability. In South America, the aquaculture of the native zooplanktivorous fish Odontesthes bonariensis ("pejerrey") has some constraints that could be overcome by applying extensive culture systems following an ecosystemic approach. This study represents the first attempt to develop ecological aquaculture in the region. An experiment of extensive cage culture was carried out in La Salada de Monasterio Lake to answer how seasonal changes, both in physico-chemical and zooplankton features, affect the performance of pejerrey culture. Three successive rearing trials were carried out in spring, summer and autumn. The cages were stocked with pejerrey; whereas others (controls) were left without fish. Lake zooplankton abundance, biomass and species composition were different among seasons, with maximum abundance mean values during summer and maximum biomass mean values during spring. The zooplankton abundance found in cages without fish was higher than that registered in cages with fish, but no differences in species composition among those cages were detected. The pejerrey showed selective feeding habits throughout the entire experiment, and they fed mostly on copepods and cladocerans of N 0.7 mm during spring and summer, especially after reaching 4 cm in total length, and on smaller copepods and cladocerans during autumn. The contribution of the different sizes of zooplankton to the gut contents was related to availability and to fish size, and the access to bigger zooplankton appeared to be a critical factor to promote better growth performance. The bigger fish were obtained in spring, when zooplankton biomass was maximum in the lake with greater representation of large cladocerans, with final fish weight eight times higher than that obtained in summer and fifty times greater than that obtained in autumn. The production obtained in spring was one and two orders of magnitude higher than that found in summer and autumn. The multiple linear regressions selected support the inference that seasonal temperature and zooplankton variations have effects on pejerrey growth in floating cages. Pampean lakes could be suitable environments to support pejerrey ecological aquaculture, and spring emerges as the better season to start an extensive culture that takes advantage of the zooplankton composition and dynamics.

“…Dorada Brycon sinuensis is an endemic species of fish of the Sinú River Basin (Córdoba, Colombia), threatened by the deterioration of its natural environment [1]. Like other bryconids, this species presents characteristics desirable for fish farming, including rapid growth, acceptance of artificial diets, easy adaptation to captivity, resistance to handling, and omnivorous diet [2]. The management of first feeding is done for only 24 h because this is the critical period of intensive larviculture of this species.…”

“…The management of first feeding is done for only 24 h because this is the critical period of intensive larviculture of this species. This technique allows the larvae to be viable for the next stages of the production process and reduces cannibalism during this critical stage [2,3]. The bryconids' life cycle is characterized by a fast embryonic stage (12-14 h to 26-28 • C); the larvae begin the exogenous feeding between 22 and 24 h after hatching (hae); management of first feeding is short (24 h).…”

“…The bryconids' life cycle is characterized by a fast embryonic stage (12-14 h to 26-28 • C); the larvae begin the exogenous feeding between 22 and 24 h after hatching (hae); management of first feeding is short (24 h). During this phase the maximum mouth opening is estimated at 20-25% of total length (5 to 6 mm); there is a short larval period (7 days); and like other bryconids, Brycon sinuensis shows strong cannibalism at the beginning of the exogenous feeding [2,[4][5][6][7][8]. This behavior causes low survival rates and heterogeneity in larval size [2,7,9].…”

Management of the First Feeding of Dorada Brycon sinuensis with Two Species of Cladocerans

The management of the first feeding is a critical stage in the viability of the larvae and fingerling rearing. So far, the first feeding of the bryconids record the best results when fed with forage larvae; thus, the aim was to evaluate two species of cladocerans as live prey in the first feeding of dorada Brycon sinuensis and to evaluate their effects on the control of cannibalism. Larvae (1.2 ± 0.15 mg and 5.9 ± 0.4 mm initial weight and total length) were fed Moina minuta (Mm), Macrothrix elegans (Me) or a mixture (50:50) of cladocerans (Mix) at a rate of 20 prey mL−1, once for 24 h. Another dorada larvae group were fed newly hatched larvae of Piaractus brachypomus (4.5 ± 0.9 mm) as forage larvae (FL) in a ratio of 2:1 (prey: predator). The larvae were stocked to 50 L−1 in aquaria with 5 L of useful volume (12 per treatment). The growth, survival, stress resistance, cannibalism mortality, and the number of prey in the gut contents were analyzed. Dorada larvae fed FL showed higher growth, but those fed Mm showed the highest survival rate (76.1 ± 6.6%) and the lowest cannibalism mortality (16.8 ± 3.7%) (p < 0.05). The use of the cladocerans allowed high survival and stress resistance (95.3 ± 2.4%), and M. minuta proved to be a suitable prey for cannibalism control in the management of the first feeding of dorada larvae.

Sorubim cuspicaudus, a migratory catfish distributed in the Magdalena, Sinú, and Catatumbo river basins, is categorized as vulnerable to extinction. Production of fingerlings in controlled environments stands as a strategic conservation approach, and larviculture is a critical phase in rearing this species. Probiotics are used for improvement in the critical stages of fingerling production. The study aimed to evaluate the use of probiotics (Bacillus subtilis and Bacillus licheniformis) during the larviculture phase of S. cuspicaudus. Larvae at 42 hours post-hatching (1.5±0.1mg, total length 5.7±0.4mm) were treated with four levels of probiotic inclusion in the water: 0, 5, 10, and 20ppm for 22 days. Water quality remained within suitable ranges for neotropical catfish species larviculture and the parameters assessed were weight gain (Gw), length gain (Gl), specific growth rate (G), survival rate (S), stress resistance (Sr), intestinal fold length (LF), and colony-forming units (CFU) count. Results showed higher Gl (22.23±3.5mm), Gw (40.0±12.6mg), G (14.9±1.5%/day), LP (205±72.7µm), and CFU (118.7±80.9) were found at 20 ppm (p<0.05). However, S and Sr exhibited no significant differences among treatments (p>0.05). The findings of this study suggest that probiotics (Bacillus subtilis and Bacillus licheniformis) could be used as an alternative to advance in the S. cuspicaudus larviculture.
