“…This feature is shown for two different months: April 2004, when more juveniles entered the study area, and September 2004, when according to the population studies, most young fish had already spent some time growing in the region11 (Fig. 7).…”

“…The individuals where the ALCBs were first noticed were collected in southeastern Brazil for a series of ecological studies, which provide detailed information about sampling procedures91011. Briefly, sampling was performed from August 2003 through October 2004 in Caraguatatuba Bay (from 23°43′25.3″S 045°24′07.1″W to 23°37′41.1″S 045°24′02.4″W), in São Paulo state.…”

The presence of a conspicuous and frequent but never-described structure in the skull cavities of sciaenid fish was noted during population studies in an urbanized bay. The ultrastructure closely resembles the cupula of neuromasts, an organ associated with the perception of the environment in teleost fish. The bodies were recorded detached in both preserved and freshly sampled individuals and without associated cilia. Prominent characteristics are acellularity, the elliptic-conic shape composed of stack-like protein lamellas, and a mesh-like appearance in cross section. These acellular lamellar cephalic bodies (ALCBs) were more abundant in larger individuals and showed temporal peaks of abundance independently of the fish size. The conic and lamellar features suggest that the deposition of protein layers follows fish growth, and the bimodality of the size of these structures in individuals indicates temporal peaks of production. These results indicate that these ALCBs are a consequence of the accretion of the cupula of neuromasts at a faster rate than they degrade. Given the novelty of this structure and the increasing records of diseases of marine organisms worldwide, an important question is whether these bodies occur subsequently to some environmental change and whether their accumulation in the skull cavities has consequences to fish health.

“…Un crecimiento de tipo alométrico con un valor de b mayor a tres, sugiere que la especie presenta una tendencia a aumentar más en peso que en longitud. Al comparar las estimaciones de los parámetros de crecimiento establecidos para S. melanocheir en la presente investigación (L∞ = 17,3 cm y K = 0,71/año) con otros congéneres como S. lanceolatus en el golfo de México (L∞ = 18,5 cm, K = 0,4/año) (Ramos-Miranda et al, 2009) y S. rastrifer en el sur de Brasil (L∞ = 20,9 cm, K = 0,37/año) (Pombo et al, 2013), la tasa de crecimiento establecida para S. melanocheir fue mayor, pero la talla asintótica fue menor. Para confirmar diferencias en el crecimiento de las especies se calculó el valor de ' para S. lanceolatus y S. rastrifer con valores de 2,14 y 2,21 respectivamente.…”

Stellifer melanocheir (Eigenmann, 1918) es una especie de pez abundante en la fauna acompañante de la pesca artesanal de camarón de aguas someras. Con el objetivo de estudiar el crecimiento la reproducción y hábitos alimentarios de la especie, se recolectaron 751 individuos (540 hembras, 187 machos y 24 indeterminados) entre septiembre de 2011 y abril de 2012 de la pesca artesanal de camarón de aguas someras del Golfo de Tortugas, Colombia. Los parámetros de crecimiento representados por la ecuación de Von Bertalanffy Lt = 17,8(1-e[−0,62(t+0,34)]) mostraron que la especie presentó un crecimiento alométricamente positivo, más rápido que algunas especies congéneres. Las hembras alcanzan la talla media de madurez (L50) a los 11,7 cm y los machos a 10,9 cm. Se reproduce continuamente con un pico entre septiembre y noviembre, y otro menor en marzo, probablemente aprovechando periodos con aumento de precipitación. La dieta de la especie es similar durante su etapa juvenil y adulta, con un espectro trófico estrecho, carcinófago, con hábitos bentopelágicos. Su principal presa son los copépodos con capturas ocasionales de camarones, las cuales aumentan en los individuos de mayor tamaño.
