Effects of a mix of Bacillus sp. as a potential probiotic for Florida pompano, common snook and red drum larvae performances and digestive enzyme activities
Provedor de dados: 5
Autores: Hauville, Marion; Zambonino-infante, J. L.; Bell, J. Gordon; Migaud, H.; Main, K. L.
This study examined the effect of a commercial mix of Bacillus sp. on survival, growth and digestive enzyme activities of Florida pompano, red drum and common snook. Larvae were fed either live feed enriched with Algamac 3050 (Control), Algamac 3050 and probiotics (PB), or the previous diet combined with a daily addition of probiotics to the tank water (PB+). Survival was not affected by the treatments for any of the species. At the end of the pompano and snook trial, standard lengths of larvae from the PB and PB+ treatments were significantly greater than for the control larvae. Microbiological analyses were performed at the end of the pompano trial, and numbers of presumptive Vibrio were not a concern in the system. For both pompano and snook,...

Snook (Centropomidae) and grouper (Serranidae) mariculture in the Gulf of Mexico and Caribbean Basin
Provedor de dados: 5
Autores: Roberts Jr, D.
Centropomidae and Serranidae, sometimes collectively misnamed "sea basses", are suitable for aquaculture in pens, ponds, and raceways around the tropical and subtropical latitudes of the world. Western Atlantic Ocean species were recently considered for farming. South Florida, Mexico, Central and South America and the Antilles areas of the Caribbean Basin have extensive areas suitable for farming groupers and snook. Principal species of interest are the common snook (Centropomus undecimalis ), the fat snook (C. parallelus ), the Nassau grouper (Epinephelus striatus ), Black seabass (Centropristis striatus ), Gag (Mycteroperca microlepis ), and jewfish (E. itajara ).

Eugenol as an anesthetic for juvenile common snook
Provedor de dados: 86
Autores: Bernardes Júnior,Jurandir Joaquim; Nakagome,Fernando Kojima; Mello,Giovanni Lemos de; Garcia,Silvano; Amaral Júnior,Hilton.
The objective of this work was to evaluate the efficacy of eugenol as an anesthetic for juvenile common snook, and to determine the minimum effective concentration for use in handling procedures. In the first trial, juvenile common snook were subjected to immersion baths at 25, 50, 75, 100, 125, and 150 mg L-1 eugenol concentrations, after which induction and recovery times were evaluated. In the second experiment, the lethal exposure time (LT50) at 75 mg L-1 was estimated. Minimum effective eugenol concentration was 50 mg L-1, andthe stage of deep anesthesia and recovery were, respectively, reached at 126.3 and 208.8 s. At 75 mg L-1, LT50 was 1,314 s, and induction time and recovery were also satisfactory; however, fish cannot tolerate over 229 s exposure.

Influência da densidade de estocagem no cultivo de juvenis de robalo-flecha mantidos em laboratório
Provedor de dados: 86
Autores: Souza-Filho,José Jerônimo de; Cerqueira,Vinicius Ronzani.
O objetivo deste trabalho foi analisar a influência da densidade de estocagem no crescimento, conversão alimentar e sobrevivência de juvenis de robalo-flecha (Centropomus undecimalis). Os peixes foram coletados em ambiente natural e treinados a aceitar dietas artificiais. Os indivíduos, com comprimento total de 13±0,4 cm e peso de 23±0,3 g foram estocados em tanques circulares de fibra de vidro de 5 m³, com água do mar e aeração contínua, nas densidades de 3, 6 e 9 peixes/m³, por 180 dias. Os valores de amônia total (0 a 0,5 mg/L), temperatura da água (23,3 a 30,6ºC), salinidade (17 a 34 g/L), pH (7,8 a 8,4) e oxigênio dissolvido (4,8 a 6,9 mg/L) apresentaram padrão similar entre os tratamentos. A conversão alimentar (1,88, 2,06 e 2,31) e a sobrevivência...

Crescimento compensatório e privação alimentar no desempenho produtivo do robalo-flecha
Provedor de dados: 86
Autores: Herrera,Leandro Amaral; Silva,Francisco da Costa; Santos,Ana Paula dos; Sousa,Otávio Mesquita de; Sanches,Eduardo Gomes.
Resumo: O objetivo deste trabalho foi avaliar o efeito da privação alimentar e a ocorrência de crescimento compensatório sobre o desempenho produtivo de formas jovens do robalo-flecha (Centropomus undecimalis). O experimento teve duração de 60 dias, em que os peixes - 35 indivíduos por tanque - foram divididos nos três seguintes grupos de tratamentos: com alimentação todos os dias (controle); com alimentação cinco dias por semana, seguidos de dois dias de jejum; e com alimentação quatro dias por semana, seguidos de três dias de jejum. Os tratamentos de privação alimentar proporcionaram indicadores de desempenho significativamente inferiores aos do controle. Formas jovens da espécie não devem ser submetidas a períodos de privação alimentar, pelos prejuízos...

Common snook fed in alternate and continuous regimens with diet supplemented with Bacillus subtilis probiotic
Provedor de dados: 86
Autores: Noffs,André Pedro; Tachibana,Leonardo; Santos,Antenor Aguiar; Ranzani-Paiva,Maria José Tavares.
The objective of this work was to evaluate the addition of Bacillus subtilis probiotic to the feed of common snook (Centropomus undecimalis) fingerlings, in alternate and continuous regimens. Six hundred and sixty fish, with average length of 5.90±0.88 cm and weight of 1.92±0.28 g, were stocked in 12 cages of 1.0 m3, with 55 fish each. The experimental design was completely randomized, with three treatments and four replicates. The treatments consisted of diet with the addition of probiotic, provided in alternate regimen for 7 days and in continuous regimen; besides a control without probiotic in the feed. Zootechnical performance, body composition, immune response, and blood parameters were evaluated. No significant differences were observed in...

Performance of common snook subjected to different feeding frequencies and rates using automatic feeders
Provedor de dados: 86
Autores: Herrera,Leandro Amaral; Santos,Ana Paula dos; Sousa,Otávio Mesquita de; Kuhnen,Vanessa Villanova; Sanches,Eduardo Gomes.
Abstract: The objective of this work was to evaluate the growth performance of common snook (Centropomus undecimalis) subjected to different feeding rates and frequencies using automatic feeders. Two experiments of 60 days each were carried out. In the first one, 20 fishes per tank were distributed in three feeding rates of: 5, 10, and 15% body weight per day. In the second experiment, 20 fishes per tank were distributed in nine tanks, in three feeding frequency: once a day, three times a day, and six times a day. Water parameters were maintained at the recommended level for the species. Final weight, body weight gain, specific growth rate, and feed conversion rate did not differ significantly between the 10 and 15% feeding rates. However, both rates...

Com o objetivo de analisar a intensidade das alterações histológicas em brânquias de Centropomus undecimalis para avaliar a qualidade da água do Parque Ecológico Laguna da Jansen, em São Luís, Estado do Maranhão, coletaram-se exemplares de peixes no período chuvoso de 2012 e amostras de água nos períodos seco de 2011 e chuvoso de 2012 para análises físico-química e bacteriológica. Os resultados mostraram que a maioria dos parâmetros físico-químicos e bacteriológicos estava de acordo com os valores estabelecidos pela Resolução do CONAMA nº 357 de 2005. As alterações histológicas observadas foram: elevação do epitélio lamelar; proliferação excessiva de células dos epitélios filamentar e lamelar causando fusão total ou parcial das lamelas; alteração da...

Autores: Michelotti,Bruna Tomazetti; Mori,Natacha Cossettin; Magnotti,Caio Cesar Franca; Heinzmann,Berta Maria; Almeida,Ana Paula Gottlieb; Cerqueira,Vinicius Ronzani; Baldisserotto,Bernardo.
ABSTRACT: Essential oils of plants whose main compound is citral showed beneficial effects when added to fish feed. The objective of the present study was to evaluate the dietary effect of the addition of citral on zootechnical parameters and digestive enzyme activities of Centropomus undecimalis. Juveniles were fed for 45 days with diets containing different amounts of citral (0.0 - control, 0.5, 1.0, and 2.0 mL per kg of diet). The water quality parameters were kept stable during the experiment and no mortality was observed. At the end of the experimental period, the treatment 0.5 mL citral per kg of diet had the lowest weight gain and specific growth rate, and the highest feed conversion, while the same parameters did not differ between the other...
