Use of chlorinated products in the disinfection of fish ponds
Massago, Haluko; Corrêa da Silva, BrunoDifferent fishes present in farms can be voracious predators of fingerlings to be stocked in the rearing. To eliminate these predators, calcium hypochlorite 65% (HC65%) and sodium dichloroisocyanurate 65% (DS65%) were evaluated in tilapia, yellow-tail characin and South America catfish juveniles. Initially, clear water assays were performed to determine the lethal concentration (LC) for these three fish species...
Zootechnical and economic performance of the Nile tilapia strain GIFT-Epagri SC...
Silva, Bruno Corrêa; Massago, Haluko; Marchiori, Natalia da Costa; Biz, Valdomiro; Silva, Tatiane CarineGrow-out performance of second-generation Epagri Tilapia strain, also called GIFT-Epagri SC02, was evaluated in the northern and middle Itajaí Valley regions. The zootechnical and economic performance of two commercial cultures for the 2016/2017 harvest and two other commercial culture for the 2017-2018 harvest was followed up. Fingerlings were derived from Epagri and producers hailed from the municipalities of...
Performance of yellow-tail lambari feeded with practical feeds containing diffe...
Massago, Haluko; Corrêa da Silva, BrunoThe aim of this research was to evaluate the practical diet crude protein (CP) diets based on the ideal protein for the growth of yellow-tail lambari Astyanax bimaculatus juvenile. The experimental design was completely randomized being 6 powder feed (18.9, 21.3, 23.7, 26.5, 28.6 and 31.2% CP), with 4 replicates each. Were used 24 aquariums (20 fish each, initial weight 1.29 ± 0.08g) with 80-liter water recircu...
Genetic characterization of selected Nile tilapia in Santa Catarina
Silva, Bruno Corrêa da; Pereira, Adriana; Massago, Haluko; Mariguele, Keny HenriqueDifferent Nile tilapia stocks belonging to the fish breeding program of the Epagri (Empresa de Pesquisa Agropecuária e Extensão Rural de Santa Catarina) were characterized by microsatellite markers. A total of nine stocks (S1 to S9) were evaluated, and for each stock the caudal fin of 30 individuals were sampled. A total of 75 alleles were found at the 11 microsatellite loci used (UNH104, UNH108, UNH160, UNH208...
Protein Performance relation of commercials diets in the nile tilapia
Silva, Bruno Corrêa; Massago, HalukoThe study aims to evaluate the zootechnical performance of Nile tilapia fed with different commercial diets and relate such results with the centesimal composition and aminogram of the commercial feeds. There were five diets evaluated (A, B, C, D, and E) indicated for the tilapia growth-out phase (200 to 600g). Two hundred and twenty-five Nile tilapia (201.5 ± 4.7g) were distributed in 15 net tanks of 1m³ insta...
Diversidade genética de quatro linhagens de Oreochromis miloticus utilizando o ...
Massago, Haluko; Ribeiro, Ricardo Pereira; Lopera Barrero, Nelson Maurício; Povh, Jayme Aparecido; Castagnolli, Newton; Gomes, Patrícia CristinaO objetivo do presente estudo foi analisar a diversidade genética de quatro linhagens de tilápia do Nilo (Oreochromis niloticus) utilizando o marcador RAPD. Foram coletadas amostras de nadadeira de estoques de juvenis das linhagens GIFT (G), Chitralada (C), Supreme (S) e Bouaké (B). Os 11 primers utilizados produziram 81 fragmentos dos quais 41,98% foram polimórficos. A porcentagem de fragmentos polimórficos (G...
