“…Because of its economic importance, the first studies of Brazilian sardine began in 1950 (Coutinho et al., ), but only recently have studies been undertaken for aquaculture purposes (Baloi, de Carvalho, Sterzelecki, Passini & Cerqueira, ). The Brazilian sardine is a clupeid with a short life cycle and high growth rate and fecundity (Perin & Vaz‐dos‐Santos, ) and is thus a good candidate for aquaculture. With diurnal feeding behaviour, Brazilian sardine in nature feed on phyto‐ and zooplankton for their entire life (Kurtz & Matsuura, ; Schneider & Schwingel, ).…”

Effect of dietary carbohydrate to lipid ratios on growth, digestive enzyme and blood metabolites of juvenile Brazilian sardines, Sardinella brasiliensis (Steindachner, 1879) AbstractThe limited availability of live bait for capturing skipjack tuna, Katsuwonus pelamis, is a bottleneck to increasing tuna production in many parts of the world. Therefore, a nutrition trial was performed to contribute to the production of the Brazilian sardine, Sardinella brasiliensis, for use as live bait. This study determined the best dietary carbohydrate to lipid ratio (CHO:L) for juvenile Brazilian sardines based on growth performance, feed utilisation, body composition, blood metabolites and digestive enzyme activity. Six isoenergetic and isonitrogenous diets were formulated with increased CHO:L ratios (2. 05, 3.41, 4.15, 5.11, 5.80 and 6.72). Each diet was randomly assigned to triplicate groups of 100 fish with mean initial body weight of 2.97 AE 0.51 g, which were fed four times a day to apparent satiation. Survival was not affected by differences in diet, however, a low CHO:L ratio stimulated growth. Juveniles fed with a rich-carbohydrate diet inhibit feed intake and protein intake. Body lipid increased as dietary lipid increased and was inversely correlated to body moisture. The diets did not affect the juvenile's blood metabolites. Alkaline and acid protease activities were not significantly different, but lipase and amylase responded positively to the dietary lipids and carbohydrates. Using segmented regression, the optimum CHO:L ratio for maximum weight gain of juvenile Brazilian sardines was estimated to be 3.41, which contain approximately 300 g kg À1 carbohydrate and 88 g kg À1 lipid.

“…The Brazilian sardine, Sardinella brasiliensis , is a schooling, pelagic fish mainly distributed between Cabo de São Tomé, Rio de Janeiro State (22°S) and Cabo de Santa Marta, Santa Catarina State (29°S) and is one of the most important marine fishery resources in Brazil (Gigliotti, Gherardi, Paes, Souza, & Katsuragawa, ; Perin & Vaz‐dos‐Santos, ). The Brazilian sardine is not only the foundation of an important canned sardine industry, but is also used extensively as live bait to capture skipjack tuna, Katsuwonus pelamis .…”

A six-week growth trial was performed to estimate the dietary protein requirements for maximum growth of juvenile Brazilian sardine (Sardinella brasiliensis) based on growth performance, feed utilization, body composition and digestive enzyme activity.Six isoenergetic diets were formulated to contain protein levels that increased from 250 to 500 g/kg. Each diet was randomly assigned to triplicate groups of 160 fish with mean initial body weight of 0.93 ± 0.13 g, which were fed four times a day to apparent satiation. Growth tended to increase with the increase in the dietary protein level up to 400 g/kg. Total protein intake was indirectly correlated to apparent protein utilization. No significant differences in whole-body composition were found between fish fed the different protein levels. Acid protease and neutral lipase activities did not show significant differences among the different protein dietary groups. Alkaline protease activity increased in fish fed up to 350 g/kg of protein and amylase activity in fish fed up to 400 g/kg. Using polynomial regression, 367 g/kg was estimated to be the optimum dietary protein requirement for maximum weight gain of juvenile Brazilian sardines.

“…The use of bivariate morphometry to describe the relationships between fish and otolith measurements is common (Cadrin and Friedland 1999, Ponton 2006, Perin and Vaz-dos-Santos 2014, including shape indices (Tuset et al 2003a, Leguá et al 2013. The association of traditional morphometry and geometric studies makes it possible to expand the use of otoliths as key elements for understanding species and populations (Rohlf and Marcus 1993, Monteiro et al 2005, Vignon 2012).…”

Summary:In order to characterize the ontogeny of Anchoa tricolor, the morphology and morphometry of sagitta otoliths were described. A total of 397 pairs of sagitta otoliths of A. tricolor (20 to 85 mm) were measured and analysed by means of digital images. Morphological description was done in terms of shape and features. The Huxley model was fitted to otolith length against total length (TL) and weight (TW), and residual analyses were done in order to detect the polyphasic growth. Six shape indices were calculated (otolith height/otolith length and otolith length/total length aspect ratios, rectangularity, roundness, relative sulcus surface and rostrum index) and after size effect removal, they were analysed in terms of TL. The results of these analyses allowed three distinct growth phases to be identified: (1) up to 40 mm TL and related to low swimming ability; (2) between 41 and 60-70 mm TL, when fish displacements increase but the first maturation has not yet occurred; and (3) after 71 mm TL, when fish become adults. Landmarks and semi-landmarks were used to analyse relative warps during the otolith development. The MANOVA analysis between the centroid size and class intervals showed significant differences in the interaction of all classes except between 71-80 and 81-90 mm.Keywords: shape index; geometric; morphometry; Engraulidae; Brazil; description.Desarrollo ontogénico del otolito sagitta de la anchoa, Anchoa tricolor, en un estuario subtropical Resumen: Se describen la morfología y morfometría de los otolitos sagitta de Anchoa tricolor con el objetivo de caracterizar su ontogenia. Se midieron un total de 397 pares de otolitos sagitta de A. tricolor (20 a 85 mm) y se analizaron por medio de imágenes digitales. La descripción morfológica se hizo en términos de forma y características. Se ajustó el modelo de Huxley a la relación longitud del otolito, longitud total (TL) y peso (TW), respectivamente, y se realizaron análisis de residuos para detectar el crecimiento polifásico. Se calcularon seis índices de forma (OH/OL y OL/LT radios de aspecto, rectangularidad, redondez, superficie relativa del sulcus e índice de rostrum) y, una vez eliminado el efecto de talla, se analizaron en términos de longitud total. Los resultados de estos análisis permitieron identificar tres fases distintas de crecimiento: (1) una fase inicial, hasta 40 mm TL y relacionada con una habilidad natatoria baja; (2) entre 41 y 60-70 mm TL, cuando los desplazamientos del pez aumentan, pero aún no se ha producido la primera madurez y (3) superior a 71 mm TL, cuando el pez es ya adulto. Se utilizaron puntos homólogos y puntos equidistantes para analizar deformaciones relativas durante el desarrollo del otolito. El análisis MANOVA entre el tamaño del centroide y los intervalos de clases de talla mostraron diferencias significativas en la interacción de todas las clases, excepto entre 71-80 y 81-90 mm.Palabras clave: índice de forma; geometría; morfometría; Engraulidae; Brasil; descripción.
