“…As effective rearing protocol is required to facilitate the adaptation during weaning of larvae to artificial diet (Rao, 2003), from the findings of the present study, it is assumed that, the weaning process helped in that direction. Previously, in O. bimaculatus, (Pradhan et al, 2014) and Osteobrama belangeri (Kumar et al, 2018), it has been reported that the larvae weaned after 7 dph showed similar survival rates with those fed just live prey (Artemia nauplii or zooplankton). Interestingly, in butter catfish, early weaning before 7 dph resulted in poor survival, however, in the present study weaning before 7 dph did not show significant variation in survival rate.…”

Background: Heteropneustes fossilis commonly known as stinging catfish is a popular indigenous fish of the Indian sub-continent. The species has a high consumer demand because of its tender flesh, low fat and high iron content, and is recommended for anaemic patients. Although the species has high consumer preference and potential for commercial aquaculture but, high mortality of larvae and difficulties in accepting compound diet during larviculture are some of the major bottlenecks. Keeping this in mind, the present study was designed to determine the earliest age at which stinging catfish can be weaned to an artificial diet. The information generated from the present study would be very helpful in improving survival during larval rearing. Methods: The larvae were randomly distributed @ 60 larvae/ tank in 21 circular FRP tanks containing 30 L water each and the feeding experiment started at 2 dph. Seven different feeding strategies depending on the type of food (zooplankton, Artemia nauplii, or microdiet) and the age at which those food items were provided to larvae, were evaluated. Result: The results indicated that larvae survival in the groups weaned after 5 days post hatch (dph) was similar to that of those fed solely with Artemia nauplii and zooplankton, although growth of larvae in the weaned groups was less. As larval growth can be compensated at later stages of the rearing process, therefore, larval survival is considered as one of the most important parameters for evaluating the weaning success. Based on the present findings, it is suggested to rear stinging catfish larvae with zooplankton without dependence upon costly Artemia nauplii, and larvae may be weaned to artificial diet after 5 dph. The findings would be very helpful for improving larval rearing of this indigenous catfish species in Indian rural areas.

“…Different studies have been conducted to evaluate better weaning strategy for H. fossilis , approaches that varied depending on the level of aquaculture development and geographic area considered. In India, Kumar et al 135 evaluated different food items and their combination for first feeding at 2–22 dph (water temperature: 28.0–29.1°C; feeding rate: at apparent satiation and food distributed at 08:00, 12:00 and 16:00 h). Particularly, the following diets administered throughout the study were evaluated: (1) Artemia nauplii, (2) mixed pond‐produced zooplankton (copepods and cladocerans), and (3) a commercial microdiet (Micro Elite 50, LuckyStar ® , Singapore).…”

Catfish (Siluriformes) are important species for aquaculture worldwide, with an annual production in 2018 of ca. 6 million t. This review focuses on reassessing larval development, first feeding, and early rearing practices of the most important farmed catfish species, along with some candidate species for aquaculture diversification: Pangasianodon hypophthalmus (Pangasiidae), Clarias gariepinus (Clariidae), Ictalurus punctatus (Ictaluridae), Pseudoplatystoma spp. (Pimelodidae), Heteropneustes fossilis (Heteropneustidae), Rhamdia quelen (Heptapteridae), Ompok bimaculatus (Siluridae), and Lophiosilurus alexandri (Pseudopimelodidade). These species are initially reared indoors from one day to two weeks and are then transferred to fertilised outdoor ponds where they either feed on natural zooplankton or compound feeds. With the exception of C. gariepinus, I. punctatus, R. quelen and P. hypophthalmus, consistent and reliable fry production is a bottleneck that limits the expansion of farming of other species, such as Pseudoplatystoma spp., H. fossilis, O. bimaculatus, and L. alexandri. Rearing systems (extensive, semi‐extensive, intensive) and feeding protocols vary with species and geographical regions. Cannibalism and size heterogeneity are common, and these features create problems for larval and fry rearing of catfish species. Information about their nutritional requirements is required for the formulation of compound feeds that can guarantee high survival and good growth of catfish fries. However, such knowledge for most species is scarce, although some data are available for I. punctatus. Further genomic resources might allow fine‐tuning rearing success. This review describes some successes in this field, and also highlights gaps in knowledge to guide future research that can promote the development of catfish aquaculture.

“…El interés en cuanto a disminución de costos en la producción masiva de alevinos de peces con fines comerciales, ha llevado a buscar estrategias para remplazar el uso de alimento vivo mediante el empleo de dietas formuladas (Frías-Quintana et al, 2010;Liu et al, 2012;Castañeda-Alvarez et al, 2014;Watanabe et al, 2016;Canada et al, 2017;Kumar et al, 2018;Palma-Cancino et al, 2019). No obstante, la principal limitante es la baja aceptación que tienen estos organismos en la fase de desarrollo larval por el consumo de estas dietas, que en muchas ocasiones, se debe principalmente al hábito alimenticio, siendo más restringido a peces carnívoros (Liu et al, 2012;Canada et al, 2017;Kumar et al, 2018). Esto ha dado lugar a investigaciones relacionadas con estrategias de adaptación al consumo de las dietas logrando resultados prometedores (Frías-Quintana et al, 2010;Liu et al, 2012;Castañeda-Alvarez et al, 2014;Prieto et al, 2015;Watanabe et al, 2016;Castro-Ruiz et al, 2019).…”

“…El uso de alimento vivo en los primeros días de desarrollo, ha sido catalogado como el principal contribuyente de dichos nutrientes y enzimas, mejorando así el desempeño y sobrevivencia de las larvas (Prieto y Atencio, 2008;Marciales-Caro et al, 2010;Sipaúba-Tavares et al, 2014;Prieto et al, 2015;Cheban et al, 2018;Mischke et al, 2019). Sin embargo, la producción de este tipo de microorganismos es en muchas ocasiones, laboriosa y costosa por el equipamiento y la mano de obra constante en el mantenimiento de cepas y cultivos; debido a esto, diversos estudios han abordado otro tipo de estrategias relativamente económicas y prácticas, como es el caso del suministro o no, de microdietas inertes en una fase de destete (Frías-Quintana et al, 2010;Liu et al, 2012;Castañeda-Alvarez et al, 2014;Watanabe et al, 2016;Canada et al, 2017;Kumar et al, 2018;Palma-Cancino et al, 2019); no obstante, el éxito en la producción de larvas con el uso de microdietas es limitado por el desconocimiento del momento de la formación de órganos digestivos especializados que permitan la digestión y asimilación, así como deficiencias nutricionales de aquéllas con respecto a las presas vivas. A continuación, se aborda el uso de estas dos estrategias de alimentación para larvas y alevinos: alimento vivo (cladóceros) y microdietas inertes.…”

Son muchos los factores que influyen en la producción de larvas y alevinos de peces, destacándose la temperatura, la calidad del agua, la especie, el estado nutricional, la calidad y cantidad del alimento disponible durante la primera alimentación, entre otros. Dicho alimento debe sostener los diferentes cambios fisiológicos y estructurales en el desarrollo de órganos y sistemas. El sistema digestivo es uno de los más importantes durante las fases tempranas de peces, debido a que es donde se da la principal absorción de nutrientes suficientes para el crecimiento y el desarrollo. No obstante, existen diferencias en el desarrollo entre las especies, considerando así, el estudio ontogénico del tracto digestivo una herramienta útil para determinar el momento oportuno de la formación de los diferentes órganos. En este sentido, conocer y entender el manejo de la primera alimentación y cómo influye en el desarrollo del sistema digestivo de larvas es un aspecto fundamental en el éxito de la producción de larvas de calidad y resistencia. Por lo tanto, el objetivo de esta revisión es ofrecer información actualizada sobre el desarrollo ontogénico y principales enzimas del sistema digestivo, así como la influencia del tipo de alimento en el desarrollo de las larvas de peces.
