中文摘要 | 在本研究中,我們採集了2010年7月至2011年11月間巴基斯坦近海的銀鯧樣品進行了其體長-體質量關係以及肥滿度的研究。其中,樣品體長6.8~21.0cm,體質量9.4~450.0g。在體長-體質量關係式中,冪指數b=3.15,說明銀鯧的生長為等速生長,回歸指數R^2=0.96,表明該關係式較好地反映了體長與體質量間的關係。基於體長對銀鯧樣品分為八組進行了肥滿度的研究,平均肥滿度指數(Kn)在12.0-13.9cm體長組達到最大值1.15,在20.0-21.9cm體長組達到最小值0.75,t-檢驗值為9.102(P<0.0001)。本研究結果與該魚種的相關研究結果相契合,並將為此地區該種重要魚類資源的研究與管理提供基礎信息。 |
英文摘要 | In this study, we present length-weight relationship and relative condition factor in silver pomfret, Pampus argenteus sampled during July 2010 to November 2011 in Pakistan. In the samples standard length (SL) was ranged 6.8-21. 8 cm and total weight 9.4-450 g was registered. In length-weigh relationship exponent b=3.51 value indicated that the fish growth is positive allometric. The coefficient of determination R^2=0.96 value showed a strong correlation between the variables. The relative condition factor Kn were characterized in eight size classes. The mean Kn values range 0.75-1.15 highest was in 12.0-13.9 size classes and lowest 0.75 in the size class of 20.0-21.9. The t-test value was 9.102, P<0.0001). Our findings shall pave a way for baseline information about an important fish species from this area and are similar to those reported from its distribution. |
