2. Recirculating system using biological aerated filters on tambaqui fingerling farming
Resumo: O objetivo deste trabalho foi avaliar um sistema de recirculação de água com uso de filtros biológicos aerados em tanques de criação de alevinos de tambaqui (Colossoma macropomum), com duas densidades de estocagem (1,4 e 2,5 kg m-3). Os biofiltros possuíam materiais semelhantes (meios) e os mesmos padrões granulométricos, mas com a ordem dos

3. Genetic Variability of Brycon hilarii in a Repopulation Program
ABSTRACT Brycon hilarii, popularly called piraputanga in Brazil, is a species distributed throughout the whole basin of the river Paraguay. In recent years, the species has been on a repopulation program due to its remarkable decline as a wild species in the region. Assessment of the genetic diversity of broodstock and fingerling stocks in repopulation progr

4. Genetic parameters and trends of morphometric traits of GIFT tilapia under selection for weight gain
The main factor considered in breeding programs for fish is growth, which can be assessed in terms of a gain in either weight or body measurements. This study was undertaken to evaluate the morphometric traits of GIFT strain tilapia (Oreochromis sp.) selected for weight gain. The data set used contained information on 6,650 animals. The genetic values of 8,5

5. Performance and isotopic composition of 13C and 15N in muscle tissue of Nile tilapia (Oreochromis niloticus) fed with different protein / Desempenho produtivo e composição isotópica de 13C e 15N no tecido muscular de tilápia do Nilo (Oreochromis niloticus) alimentada com diferentes fontes protéicas
Alternative sources of food have been studied in substitution for fishmeal in aquaculture, and it may result in a difference in incorporation of carbon and nitrogen, depending on the nutritional value and availability of the source. Two experiments were designed to quantify the participation of different protein sources in the muscle tissue in juvenile and p

6. Morphologic analysis of developmental phases and gill ontogenesis in neotropical species Poecilia vivipara (Cyprinodontiformes: Poeciliidae) exposed to different salinities
The present study evaluated and characterized the different phases of development and the cell types present in the gill epithelium of embryos, larvae, and fingerlings of guppy (Poecilia vivipara Bloch & Schneider, 1801) specimens exposed to water with salinity ranging from 0‰ to 20‰. The development of P. vivipara was classified into eight phases. The y

7. Genetic diversity of piracanjuba used in stock enhancement programs with microsatellite markers
The objective of this work was to estimate the genetic diversity of a Brycon orbignyanus lot used in stock enhancement programs, using microsatellite markers. Samples of 44 broodstocks, 70 larvae and 69 fingerlings, were analyzed with amplification of five loci described for Brycon opalinus. The number of alleles, the observed (Ho) and expected (He) heterozy

8. Diferentes itens alimentales na alevinagem do surubim Pseudoplatystoma corruscans (Spix &Agassiz,1829)
O experimento foi realizado na estação de piscicultura de Itiúba Companhia de Desenvolvimento dos Vales do São Francisco e do Parnaíba CODEVASF, Porto Real do Colégio, Alagoas. O objetivo foi fornecer itens alimentares alternativos, de fácil acesso, durante a alevinagem do surubim Pseudoplatystoma corruscans, visando fomentar a criação da espécie n

9. Resfriamento e criopreservaÃÃo do sÃmen de curimba Prochilodus lineatus (Valenciennes, 1836) / Semen cool storage and cryopreservation of curimba Prochilodus lineatus (VALENCIENNES, 1836)
Curimba (Prochilodus lineatus) is a species of native fish of the Grande river. This species is commercially important for being supplied as food to other ecological or commercial species, of interests, during the fingerling production. Moreover, it is protein source of high quality for marginal and devoid populations. The objective of this work was to devel

10. Avaliação de densidades de estocagem de alevinos da tilápia Oreochromis niloticus (linhagem Chitralada) cultivado em gaiolas.
Cage tilapia culture in Northeast region had grown very fast in the last years, where the climate provides adequate culture conditions during all the year. This kind of culture normally is developed in two culture phases: fingerlings or nursery phase and growout phase. Both of them need improvements in the management techniques and in the stocking densities,

11. Dietetic vitamin a requirements of nile tilapia oreochromis niloticus. / Exigência nutricional de vitamina A para alevinos de tilápia do nilo Oreochromis niloticus.
O excesso de vitaminas lipossolúveis na dieta pode ser acumulado no fígado e causar hipervitaminose em animais. Os objetivos deste trabalho foram determinar a exigência nutricional em vitamina A para juvenis da tilápia do Nilo Oreochromis niloticus, avaliar o desempenho da espécie através do ganho de peso e conversão alimentar e quantificar os depósi
