Na primeira etapa avaliaram-se seis dietas: Artemia sp., pl?ncton, ra??o, ra??o + Artemia sp., ra??o + pl?ncton, larvas de Prochilodus sp. (curimba), e quatro salinidades de ?gua (0, 2, 4 e 6?), ambos experimentos com distribui??o inteiramente casualizada e dura??o de dez dias. As vari?veis avaliadas: biomassa, sobreviv?ncia, comprimento total, peso final e taxa de crescimento espec?fico foram mensurados ao final dos experimentos. J? os par?metros de qualidade de ?gua, temperatura, oxig?nio, pH e condutividade el?trica foram aferidos a cada tr?s dias. O alimento larva de curimba resultou em maior sobreviv?ncia (47,2%) e biomassa total (2,5g) do que os demais tipos, que foram similares entre si. J? os demais par?metros - peso, comprimento e a taxa de crescimento espec?fico n?o diferiram entre si, quando as larvas foram alimentadas com os diversos tipos de alimentos. As larvas submetidas ?s salinidades apresentaram melhores resultados, sendo que as cultivadas sob 2? diferiram (P<0,05) das cultivadas a 0?, apresentando maiores sobreviv?ncia (52,5 contra 6,6%) e biomassa total (0,49 contra 0,23g). Portanto, recomenda-se a utiliza??o de larvas de Prochilodus sp. (curimba) como primeiro alimento vivo e a salinidade da ?gua de 2?, caso utilize-se Artemia sp. como alimento. Na segunda etapa, ap?s a determina??o do alimento e salinidade adequados, realizaram-se mais dois experimentos, que consistiram em determinar o momento ideal de se realizar a transi??o alimentar (a partir do 3?, 5? e 7? dia de vida, com tr?s dias de coalimenta??o com larva de curimba), e avaliar n?veis de inclus?o de protease ex?gena (0, 0,02 e 0,2%) na dieta de larvas de piabanha-do-Pardo Brycon sp., ambos experimentos com distribui??o inteiramente casualizada e dura??o de quinze e dezessete dias, respectivamente. Foram avaliadas as mesmas vari?veis da primeira etapa experimental. Os diferentes per?odos de transi??o alimentar e n?veis de protease ex?gena n?o interferiram nos par?metros de qualidade da ?gua. Os animais que foram submetidos ? transi??o alimentar no 7? dia de vida apresentaram melhores resultados para comprimento (23,1 mm), peso (110,9 mg) e TCE (25,5 %), sendo similares em biomassa e sobreviv?ncia aos do 5? dia de transi??o. Portanto, a transi??o pode ser realizada no 5? dia de vida. Os n?veis de inclus?o de protease ex?gena na ra??o comercial n?o influenciaram no desempenho dos animais. Verificou-se que as vari?veis analisadas s?o importantes para otimiza??o da larvicultura, sendo de fundamental import?ncia a utiliza??o de alimento vivo na dieta de larvas de piabanha-do-Pardo Brycon sp., assim como a realiza??o da coalimenta??o. Entretanto, mais estudos s?o necess?rios sobre a utiliza??o de enzimas ex?genas na dieta desses animais.Submitted by Rodrigo Martins Cruz (rodrigo.cruz@ufvjm.edu.br) on 2015-12-17T13:50:48Z No. of bitstreams: 2 marcos_vinicius_coraspe_amaral.pdf: 475313 bytes, checksum: c342159473f70bee4a02057245f1b0d7 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Approved for entry into archive by Rodrigo Martins Cruz (rodrigo.cruz@ufvjm.edu.br) on 2015-12-17T13:51:07Z (GMT) No. of bitstreams: 2 marcos_vinicius_coraspe_amaral.pdf: 475313 bytes, checksum: c342159473f70bee4a02057245f1b0d7 (MD5) license_rdf: 0 bytes, checksum: d41d8cd98f00b204e9800998ecf8427e (MD5)Made available in DSpace on 2015-12-17T13:51:07Z (GMT).

Programa de P?s-Gradua??o em Zootecnia, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2011.ABSTRACT Due to the feeding is a critical point in the larviculture of piabanha-do-Pardo Brycon sp. There were conducted four experiments in two stages in the fish culture station of the Machado Mineiro hydroelectric, in the Red Water city-MG, for adequacy of feeding management of native species. In the first step we evaluated six diets: Artemia sp., plankton, ration, ration + Artemia sp., ration + plankton, Prochilodus sp. Larvae (curimba) and the four water salinities (0, 2, 4 and 6?), both fully randomized experiments with distribution and duration of ten days. The evaluated variables: biomass, survival, total length, final weight and specific growth rate were measured at the end of the experiments. Since the parameters of water quality, temperature, oxygen, pH and electrical conductivity were measured every three days. The curimba larvae food resulted in higher survival (47.2%) and total biomass (2.5 g) than other types, which were similar. As for the other parameters, weight, length and specific growth rate did not differ for larvae fed with different types of food. Larvae subjected to salinity showed the best results, and those grown in 2?, differed (p<0.05) of cultivated at 0?, showing higher survival (52.5 compared with 6.6%) and total biomass (0.49 against 0.23 g). Therefore we recommend the used of larvae of Prochilodus sp. (curimba) as the first live food and water salinity 2?, if it considered to use the Artemia sp. as food. In the second step, after determining the appropriate food and salinity, there was held over two experiments. These consisted of determining the ideal time to make the dietary transition (from 3, 5 and 7 days of life, three days of feed training with curimba larvae), and assess inclusion levels of exogenous protease (0, 0, 02 and 0.2%) in the diet of the piabanha-do-Pardo Brycon sp. larvae, both fully randomized experiments with distribution of fifteen and seventeen days, respectively. There were assessed the same variables of the first experimental stage. The different transition periods and levels of dietary exogenous protease did not interfere with water quality parameters. The animals that were subjected to solid foods on the 7th day of life showed better results for length (23.1mm), weight (110.9mg) and TCE (25.5%), being similar in biomass and survival considering the 5th day of transition. Therefore, the transition can be performed on the 5th day of life. The inclusion levels of exogenous protease in the commercial diet had no effect in animal performance. It was found that the variables are important for optimizing the hatchery, showing fundamental importance the use of live food in the diet of larvae piabanha-do-Pardo Brycon sp., as well as the realization of co-feeding. However, more studies are needed on the use of exogenous enzymes in the diet of these animals.porUFVJMA concess?o da licen?a deste item refere-se ao ? termo de autoriza??o impresso assinado pelo autor, assim como na licen?a Creative Commons, com as seguintes condi??es: Na qualidade de titular dos direitos de autor da publica??o, autorizo a Universidade Federal dos Vales do Jequitinhonha e Mucuri e o IBICT a disponibilizar por meio de seus reposit?rios, sem ressarcimento dos direitos autorais, de acordo com a Lei n?
