斑石鲷早期发育的异速生长模式
Allometric growth pattern during early ontogeny of spotted knifejaw (Oplegnathus punctatus)
摘要
Abstract
Early ontogenesis of spotted knifejaw (Oplegnathus punctatus) was investigated using morphology and morphometrics to study the allometric growth pattern. Spotted knifejaw were reared at (24 ± 0.3)℃ from hatching to 70 days post-hatching (d), and total length, body weight, and allometric growth of important organs were deter-mined. Therefore, the increases in the total length and body weight were consistent with the cubic function and dis-played an S-curve with three distinct stages. Allometric growth patterns were detected between different organs (head, mouth, eyes, and fins) and total length and featured inflection points. The growth characteristics of the head length (with an inflection point at 35 d), rostrum length (29 d), and mouth width (30 d) changed from positive al-lometry to isometry around the infection points, whereas eye diameter (22 d) and tail fin length (32 d) changed from positive to negative allometry. Body height (32 d) maintained positive allometric growth during 0–70 d, with a dis-tinctly lower growth rate after the reflection point than that before. These results indicate that the spotted knifejaw develop the most important organs using an allometric strategy primarily to adjust themselves to the surroundings and achieve a higher survival rate.关键词
