“…In this study, we describe a reliable method to induce final oocyte maturation in the Surubí, P. fasciatum , using ovaprim at the recommended dosage (0.5 mL kg −1 ). This result further supports the finding that the combination of LH‐RHa and an anti‐dopamine factor, here domperidone, is a potent inductor of final oocyte maturation in a broad range of fish species (Lin, van der Kraak, Liang, Peng, Li, Lu, Zhou, Chang & Peter 1986; Peter, Lin & Van der Kraak 1988) and particularly in catfish species (De Leeuw, Goos, Richter & Eding 1985; Goos, Joy, De Leeuw, Van Oordt, Van Delft & Gielen 1987; Richter, Eding, Goos, De Leeuw, Scott & Van Oordt 1987; Legendre, Linhart & Billard 1996; Alok, Krishnan, Talwar & Garg 1998). One of the advantages over carp pituitary extract (CPE), which is frequently used in fish farms, is that the biological activity of ovaprim or other LH‐RHa preparations is standardized and constant if the products are stored properly.…”

Brooders of Surub|¤ (Pseudoplatystoma fasciatum) were caught in the Ichillo River (Bolivian Amazon) and adapted to captivity conditions for 1 year in the facilities of the experimental aquaculture station of 'El Prado' (Santa Cruz de la Sierra) under natural temperature and photoperiod conditions. Induced reproduction was obtained by means of Ovaprim s (Syndel, Canada) injections and arti¢cial fertilization. Sperm and ova were obtained by gentle stripping of male and female brooders. Fertilized eggs were incubated in 60 L Zug jars. A mean hatching rate of 73.7 AE 19.0% was obtained after 24 h at 26.5 1C. For larval rearing, several protocols were tested with different settings of photoperiod, light intensity, food type and period of distribution, and stocking density. The best survival rates were obtained with Artemia nauplii feeding in total darkness. A high level of aggressiveness between larvae and precocious appearance of jumpers was observed, but these can be controlled with appropriate rearing conditions. Values (n 5 23) represent minimum, maximum, mean and standard deviation (SD).Aquaculture Research, 2008, 39, 764^776 Induced breeding of Pseudoplatystoma fasciatum J Nun ì ez et al.

“…Multiple spawning is an effective strategy to improve the seed supplies in aquatic animals (Deoraj et al, 1998;Mcevoy & Mcevoy, 2006). In this study, with the same feeding rate (1%) and protein level (40%), the rates of fertilization and hatching were lower in the second spawning compared with the first spawning.…”

Nutritional components and feeding strategies are multifarious amongst different producers, whereas they are just designed for fish farming but not suitable for improving the reproductive performance of broodfish. Yellow catfish (Pelteobagrus fulvidraco), an omnivorous species, is one of the important aquaculture fish in China. In order to improve the reproductive performance of female yellow catfish (119.86-134.54 g), four feeding strategies (0.5%, 0.75%, 1% and 1.5% BW/d) and three dietary protein levels (34%, 40% and 46%) were examined, respectively, in the two separate trials. The females with moderate feed restriction (1%) showed significant lower mesenteric fat index (MFI) and higher gonadosomatic index (GSI) than the satiation group (1.5%) and excessive feeding restriction groups (0.5% and 0.75%). Females with high MFI were difficult to be artificially propagated and showed a high mortality rate, whilst the fish at 1.0% feeding rate displayed low mortality rate and high ratios of spawned fish, as well as high percentages of fertilization and hatching. Meanwhile, the offspring of 1.0% feeding rate group showed a low malformation rate and high survival rate. Multiple spawning in the same breeding season are applied in yellow catfish to reduce the number of parent fish and increase the fry production, and gonadal recrudescence after spawning might be affected by different nutrient values including dietary protein levels. In the second trail, female yellow catfish were fed with 34%, 40% and 46% crude protein diet at 1% feeding rate for the second spawning, and the best reproductive and breeding performances were observed in the fish group with 46% crude protein diet. These results demonstrate that 1% feeding rate is optimum for the spawning and reproductive performance of female yellow catfish for the first artificial spawning, and 46% dietary protein group had the best reproductive performances in the second spawning.

“…Clarias dussumieri has very high consumer preference as a food fish with medicinal and nutraceutical properties due to the presence of high concentration of physiologically available iron, necessary for the synthesis of haemoglobin and essential amino acids (Padmakumar et al 2004). Much of the research in India, has been centred on the breeding and propagation of Clarias magur (Sahoo et al 2008) and Heteropneustes fossilis (Alok et al 1998;Bindu et al 2009), and little work has been carried out on C. dussumieri (Padmakumar et al 2004;Aneesh et al 2013). Owing to their close morphological similarity with C. magur, the species is often wrongly identified and reported in publications implying their abundance.…”

Spawning occurred after 12-14 hr of injection and fertilized eggs hatched after 16:30hr. Larval rearing was carried out in cement cisterns and the larvae attained a mean size of 51.6±1.6mm in 60 days. Since brooders of this species have become extremely rare in nature, the present study on captive breeding by hormonal manipulation methods without sacrificing the male fishes, assumes significance for conserving this endemic species.
