Producing high-quality hybrid catfish with freshwater fish oil in Germany

Tridge summary

A study conducted by Dr. Dušan Palić of Ludwig-Maximilians University and Dr. Kriangsak Mengumphan of Maejo University, published in Aquaculture Reports, found that supplementing diets for hybrid catfish broodstock with low levels of freshwater fish oil can improve their performance and reproductive indicators. The research indicated that the supplementation provides additional dietary energy and enhances the palatability of the standardized food. The study used freshwater fish oil due to its cost-effectiveness and sustainability, as it is a byproduct of industrial catfish processing. This finding could solve a challenge for Thai aquaculture by improving the quality of broodstock, which is crucial for producing high-quality eggs, larvae, and fingerlings for grow-out farming.

Low levels of freshwater fish oil can go a long way in improving performance indicators of aquacultured hybrid catfish broodstock. This was observed in hybrid catfish broodstock fed with one and two per cent FFO-supplemented diets in an experiment at the Maejo University in Thailand. “We found out that supplementation of low levels of freshwater fish oil to standard manufactured fish food improves overall condition and increases reproductive indicators in hybrid catfish broodstock,” Dr. Dušan Palić of the Ludwig-Maximilians University in Germany and Dr. Kriangsak Mengumphan of Maejo University told Hatchery International. Palić and Mengumphan are part of the team that conducted the study, “Effect of freshwater fish oil feed supplementation on the reproductive condition and production parameters of hybrid catfish (Pangasius larnaudii x Pangasianodon hypophthalmus, Sauvage, 1878) broodstock”, published in Aquaculture Reports. There are two probable reasons behind the effect of the ...
