Abstract

The present study provides the first indication of the life-history traits, including, population structure, growth pattern, condition factor, form factor (a_3.0), size at first sexual maturity (L_m), natural mortality (M_W) and optimum catchable length (L_opt), of three Ambassid (Chanda nama, Parambassis lala and Parambassis ranga) fishes from the Mathabhanga River in southwest Bangladesh. A total of 370 individuals were occasionally collected from August 2017 to July 2018 with cast nets, gill nets, square lift nets, and conical- and box-traps. The total length (TL) ranged from 2.4 to 7.5 cm for C. nama, 1.9–3.8 cm for P. lala and 1.8–6.5 cm for P. ranga. The length-frequency distributions (LFDs) showed the 4.0–5.0 cm TL size group for C. nama and the 3.0–4.0 cm TL size group were numerically dominant for P. lala and P. ranga. The length–weight relationships (LWRs) indicated isometric growth for C. nama, and positive allometric growth for P. lala and P. ranga. All the LWR values were very significant (p < .001), with all r² values > .950. Based on the Spearman rank correlation test, body weight (BW) versus Fulton's-condition factor (K_F) was extremely correlated (p < .001), indicating a better wellbeing for these species. The a_3.0 value was 0.0082, 0.0138 and 0.0104 for C. nama, P. lala and P. ranga, respectively. Based on the maximum length (L_max), the L_m was 4.4 cm TL for C. nama, 2.5 cm TL for P. lala, and 4.0 cm TL for P. ranga. Based on the asymptotic length (L_∞), the L_m was 4.88 cm TL for C. nama, 2.63 cm TL for P. lala, and 4.28 cm TL for P. ranga. The M_W value was 2.2, 3.3 and 2.7/year for C. nama, P. lala and P. ranga, respectively. The optimum catchable length (L_opt) was 5.36 cm TL for C. nama, 2.75 cm TL for P. lala and 4.65 cm TL for P. ranga. The findings of the present study should be very useful for effective and sustainable management of these fishes in the Mathabhanga River and the connecting ecosystems.

孟加拉国西南部Mathabhanga河三种大使鱼(Chanda nama, Parambassis lala和Parambassis ranga)的生活史特征

本研究首次揭示了孟加拉国西南部Mathabhanga河3种大使鱼(Chanda nama、Parambassis lala和Parambassis ranga)的生活史特征，包括种群结构、生长模式、条件因子、形态因子(a3.0)、初次性成熟时大小(Lm)、自然死亡率(MW)和最佳可捕长度(Lopt)。2017年8月至2018年7月期间，采用撒网、刺网、方形吊网、锥形诱蚊器和箱型诱蚊器等方法偶尔捕获了370只个体。柽柳的总长度(TL)为2.4 ~ 7.5 cm，拉拉为1.9 ~ 3.8 cm, ranga为1.8 ~ 6.5 cm。长度-频率分布(LFDs)显示，紫花苜蓿的TL大小组为4.0 ~ 5.0 cm，拉拉和ranga的TL大小组为3.0 ~ 4.0 cm。长度-重量关系(LWRs)表明，柽柳的生长为等速生长，而柽柳和柽柳的生长为异速生长。所有LWR值都非常显著(p <.001)， r2值均为>.950。根据Spearman秩相关检验，体重(BW)与富尔顿病因子(KF)极相关(p <.001)，表明这些物种的健康状况有所改善。三种植物的a3.0值分别为0.0082、0.0138和0.0104。以最大长度(Lmax)计算，花蒿的最长长度为4.4 cm，拉拉蒿的最长长度为2.5 cm, ranga的最长长度为4.0 cm。基于渐近长度(L∞)的分析表明，C. nama的Lm为4.88 cm TL, P. lala为2.63 cm TL, P. ranga为4.28 cm TL。纳玛、拉拉和ranga的MW值分别为2.2、3.3和2.7/年。柽柳的最佳可捕长度分别为5.36 cm TL、2.75 cm TL和4.65 cm TL。本研究结果对马萨班加河及其相连生态系统中这些鱼类的有效和可持续管理具有重要意义。
