dc.description | "La proporción entre sexos de 421 ejemplares del callo de hacha negra Atrina (Servatrina) oldroydii Dall 1901 capturados entre julio y diciembre de 2007 en un banco localizado en el Pacífico mexicano, entre los estados de Sinaloa y Nayarit, sobreexplotado hasta su desaparición, fue de 1.00 machos y 1.23 hembras, con dominancia signicativa de hembras. Los valores medios de la longitud y del ancho de las valvas fueron 24.7 ± 1.8 y 15.4 ± 1.2 cm, con pesos medios total y del callo de 303.5 ± 86.46 y 19.5 ± 7 g, respectivamente. Las distribuciones de tallas y pesos unimodales sugieren que es una población unigeneracional; con crecimiento isométrico, sin diferencias entre talla, peso y relaciones talla-peso de los sexos, con organismos en diferentes fases de desarrollo gonadal, estando ausente las fases de desove y postdesove." | |
dc.description | "The male: female ratio of 421 specimens of the black pen shell Atrina (Servatrina) oldroydii Dall 1901, obtained between july and december 2007 from a natural bed detected in the Mexican Pacic between the states of Sinaloa and Nayarit and exploited until its disappearance, was 1 male: 1.23 females, with a signicant female dominance. Mean shell length and width were 24.7 ± 1.8 and 15.4 ± 1.2 cm, and the mean total weight and that of the adductor muscle were 303.5 ± 86.46 y 19.5 ± 7 g respectively. Size and weight distributions were unimodal, indicating a single generation population, and their analysis indicated isometric growth with no signicant dierences between mean sizes, weights and size-to weight relationships of males and females." | |
