| 1 | The potential of Hoplias malabaricus(Characiformes:Erythrinidae),a Neotropical carnivore,for aquaculture显示文摘We describe key production-related traits of trahira(Hoplias malabaricus),an aquaculture candidate species,in a semi-intensive fish farming system.We quantified growth from hatch through grow-out at two stocking densities and evaluated fillet protein,lipids and fatty-acid content.We made 2430 observations of growth and morphometrics on 270 juvenile fish allocated to four fish ponds,two at 5 fish/m^(2)(90 animals)and two at 10 fish/m^(2)(180 animals)through 11 months.The fish reached an average length of 27.5 cm(±0.38)and 27.0 cm(±0.24),and weight of 263.0 g(±10.54)and 246.7 g(±6.89),respectively,at the low and high densities.There was no significant difference in weight(P>0.05)between the densities for any of the parameters assessed,and hence the same growth curve applied to both densities(A=292.9;B=28.1;and K=0.65).Standard length,however,differed significantly(P<0.05)between densities,with K=0.35 at the low and K=0.29 at the high density.At both stocking densities,total lipids increased throughout the trial,while protein content decreased.Oleic acid(C18:0)increased throughout the experimental period,while docosahexaenoic acid and the n3/n6 profile decreased,with no differences among stocking densities.Hoplias malabaricus may prove a viable aquaculture species in Neotropical regions,where development of native species may contribute to sustainable aquaculture production. | Marcos Daniel Renó Faria Aderbal Cavalcante-Neto Ivan Bezerra Allaman Aline Dal’Olio Gomes Renata Guimarães Moreira Eric M.Hallerman Alexandre Wagner Silva Hilsdorf | 2019 | Aquaculture and Fisheries2019，4，3： | 0 |
