Development, nutrition, and rearing practices of relevant catfish species (Siluriformes) at early stages

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

A new species of torrent catfish, Liobargus hyeongsanensis, is described from rivers and tributaries of the southeastern coast of Korea. The new species can be differentiated from its congeners by the following characteristics: a small size with a maximum standard length (SL) of 90 mm; body and fins entirely brownish-yellow without distinct markings; a relatively short pectoral spine (3.7-6.5 %...
متن کاملPerformance Validation at Early Stages of Software Development
We consider what aspects of software performance can be validated during the early stages of development, before the system is fully implemented, and how this can be approached. There are mature and successful methods available for immediate use, but there are also difficult aspects that need further research. Ease of use and integration of performance engineering with software development are ...
متن کاملEvaluation of salinity tolerance of different clover species at germination and seedling stages
In order to study the effects of salinity stress on growth indices of three clover species including, Trifolium resupinatum, T. alexandrinum, and T. incarnatum, an experiment was conducted as factorial based on a completely randomized design arrangement with three replications. Factors included seven levels of salinity stress (0, 41, 82, 123, 164, 205, and 246 mM) and three clover species. Diff...
