In order to choose an adequate diet that provides fast and consistent gonad maturation, it was evaluated the effect of three different diets (AMF Aphytec's maturation feed with minced Cyclop-Eez, GFF Gamma frozen food and IMD Improvit marine diet) on fertility, embryonic develop duration, maturation period and fatty acid profile of eggs, muscle and hepatopancreas samples. GFF treatment promoted relatively shorter maturation period (28 ± 6 days), regular and reliable spawning events, with good fertility rates (249 ± 165 larvae/ individual spawning) and no decrease in larvae production. However, GFF presented some dissimilarities from wild-caught shrimps concerning eggs essential fatty acids (EFA) and polyunsaturated fatty acid (PUFA) content, which may influence eggs and larvae quality. A commercial rotation schedule of parental broodstock was designed to occur in periods of 6 months, with a 4 weeks time gap between groups to guarantee continuous larvae production. To choose a balance diet that promotes high survival and growth rates, it was evaluated the effect of three different diets (AF Algornose feed, AGF Aphytec's growth feed with minced Cyclop-Eez and DDF Dainichi dry fed) on growth and survival rates of rearing postlarvae. Juvenile fatty acid profile of each treatment was evaluated. No significant differences were observed in mortality rates, with DDF presenting the highest survival rate (90 ± 4%). DDF treatment promoted the fastest growth rates, with a significant higher proportion of Commercial-Small (TL>20mm) juveniles (37 ± 3%), 89 days after settlement. DDF provides high levels of PUFA and HUFA, including the main essential fatty acids. A count-down size selection schedule was designed to evaluate juvenile growth. It should occur for the first time around 40 to 45 days after settlement and then every 15 days, until all juveniles reach commercial sizeResumo alargado disponível em portuguêsNarciso, Luís, 1959-Schaff, BrianRepositório da Universidade de LisboaRocha, Ana Patrícia Pereira, 1984-2010-07-27T08:56:11Z20082008-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfapplication/pdftext/xmlhttp://hdl.handle.net/10451/1239enghttp://catalogo.ul.pt/F/?func=item-global&doc_library=ULB01&type=03&doc_number=000561327info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-08T15:40:36Zoai:repositorio.ul.pt:10451/1239Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T21:27:53.722360Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
