Resumo: Aquaculture water reuse system com be applied to saline tolerant species as an alternative for brackish water ponds. Therefore, the aim of this study was to evaluate the influence of salinity on the variables of water quality, the performance and welfare indicators on Nile tilapia (Oreochromis niloticus) culture with biofloc system. Five treatments were performed involving the salinities of 0, 4, 8, 12 and 16 g/L with three replicates. The fishes were stoked in fiberglass tanks (800L) and cultured for 90 days at a density of 30 fishes/m3 and average initial weight of 93,8 g. Molasses was used as a organic carbon source for controlling the total ammonia nitrogen levels (NAT) and induce the development of heterotrophic bacteria during the production cycle. During the study were evaluate variables of the water quality, performance ratios and hematological indicators, related to welfare of fishes. The temperature, chlorophyll-a, settleable solids and total suspended solids showed no statistical difference between salinities (p≥0,05). The average levels of NAT (3.94 mg/L) and nitrite nitrogen (0.82 mg/L) were lower in salinity 0 g/L. As the zootechnical performance, the final weight ranged 256-280 g with feed conversion rate between 1.4 and 1.6. The daily weight gain did not differ between salinity 0, 4 and 16 g/L (2.1, 1.9 and 1.9 g/day, respectively) (p≥0,05). Highest yields were obtained in salinities 0 (8.4 Kg/m3) and 16 g/L (8.0 Kg/m3) and the salinities 4, 8 and 12 g/L (7.9, 7.4 and 7.6 Kg/m3, respectively) differed only the lower salinity proposal (0 g/L). Survival, which ranged between 97 and 100% without statistical difference between treatments (p≥0,05), was not impaired with increasing salinity. In relation to animal welfare, glucose was shown to be higher in fish undergoing treatment 16 g/L (76.0 mg/dL) and above the reference values for the baseline on fish (<60.0 mg/dL). However, hemoglobin and hematocrit concentrations were not significantly different between treatments (p≥0,05). The weight and length data indicated smaller dispersion in the treatment 4 g/L. Growth coefficients (b) show differences in the degree of allometry in the treatment 0 (2,967), 4 (2,969) and 16 g/L (2,796), relative to treatment 8 (3,020) and 12 g/L (3,020). With these results, it is concluded that salinities above 4 g/L can interfere in the control of water quality variables; salinities of 8 and 12 g/L can adversely affect the growth performance and, fish welfare can be compromised in salinity 16 g/L.

Portanto, o objetivo deste trabalho foi avaliar a influência da salinidade nas variáveis de qualidade da água, desempenho zootécnico e indicadores de bem-estar no cultivo da tilápia do Nilo (Oreochromis niloticus) com sistema de biofloco. Foram adotados cinco tratamentos, envolvendo as salinidades de 0, 4, 8, 12 e 16 g/L, com três repetições. Os peixes foram estocados em tanques de fibra de vidro (800L) e cultivados por 90 dias, numa densidade de 30 peixes/m3 e peso médio inicial de 93,8 g. Foi utilizado melaço como fonte de carbono orgânico para controlar os níveis do nitrogênio da amônia total (NAT) e induzir o desenvolvimento de bactérias heterotróficas durante o ciclo produtivo. No decorrer do estudo foram avaliadas as variáveis de qualidade da água, índices de desempenho e indicadores hematológicos relacionados ao bem-estar dos peixes. A temperatura da água, clorofila-a, sólidos sedimentáveis e sólidos suspensos totais não diferiram entre as salinidades (p≥0,05). Os níveis médios de NAT (3,94 mg/L) e nitrogênio do nitrito (0,82 mg/L) foram menores na salinidade 0 g/L. Quanto ao desempenho zootécnico, o peso final variou de 256 a 280 g, com fator de conversão alimentar entre 1,4 e 1,6. O ganho de peso diário não diferiu entre as salinidades 0, 4 e 16 g/L (2,1, 1,9 e 1,9 g/dia, respectivamente) (p≥0,05). As maiores produtividades foram obtidas nas salinidades 0 (8,4 Kg/m3) e 16 g/L (8,0 Kg/m3) e as salinidades 4, 8 e 12 g/L (7,9, 7,4 e 7,6 Kg/m3, respectivamente) diferiram apenas da menor salinidade proposta (0 g/L). A sobrevivência, que variou entre 97 e 100% sem diferença estatistica entre os tratamentos (p≥0,05), não foi prejudicada com o aumento da salinidade. Com relação ao bem estar animal, a glicose mostrou-se mais elevada em peixes submetidos ao tratamento 16 g/L (76,0 mg/dL) e esteve acima do valor de referência para o estado basal em peixes (<60,0 mg/dL). Contudo, as concentrações de hemoglobina e hematócrito não apresentaram diferença estatística entre os tratamentos (p≥0,05). Os dados de peso e comprimento indicaram menores dispersões no tratamento 4 g/L. Os coeficientes de crescimento (b) demonstraram diferenças no grau de alometria nos tratamentos 0 (2,967), 4 (2,969) e 16 g/L (2,796), em relação aos tratamentos 8 (3,020) e 12 g/L (3,020). Com estes resultados, conclui-se que salinidades acima de 4 g/L podem interferir no controle das variáveis de qualidade da água; salinidades de 8 e 12 g/L podem prejudicar o desempenho zootécnico e, o bem estar dos peixes pode ser comprometido na salinidade 16 g/L.Submitted by Mario BC (mario@bc.ufrpe.br) on 2017-11-01T12:54:07Z No. of bitstreams: 1 Rafael Liano de Souza.pdf: 582753 bytes, checksum: 7c4b53c3cd1054e8bdb134808fd5ec4f (MD5)Made available in DSpace on 2017-11-01T12:54:07Z (GMT).
