摘要
摘要这项工作是第一次研究宽鳍小蠊在其自然栖息地之外的生长。本研究的目的是调查阿曼外来物种(Wadi Al Bahayes)拉氏P.latipina种群的生长参数。2020年6月和8月,用124条鱼研究了Wadi Al Bahayes(阿曼;北纬23°40′47〃;东经58°11′36〃)的拉氏小蠊种群结构。在这项研究过程中,确定了每个性别、年龄、体重和体型组成的个体数量。此外,还计算了总长度-重量关系(LRW),以及von-Bertalanfy生长方程。计算平均生长性能(phi-prime)和条件因子。男性占人口的37.10%,女性占人口的62.90%。长重关系和von-Bertalanfy生长方程为:雄性W=0.0214×L2.7889R2=0.9221,Lt=11.46(1−e−0.127(t+2.71)),雌性Lt=14.51(1−e−0.072(t+3.98))。雄性的平均生长性能和条件因子计算为1.22,雌性为1.18,所有标本为1.54。研究表明,该物种的种群具有广泛的年龄范围。因此,强烈建议对这种外来物种进行监测。
Growth parameters of Poecilia latipinna (Lesueur, 1821) (Actinopterygii, Poeciilidae) – an introduced species in brackish water of Wadi Al-Bahayes (Oman)
Abstract This work is one of the first studies on the growth of Poecilia latipinna outside its natural habitat. The objective of our study was to investigate the growth parameters of the population of P. latipinna, which is an alien species in Oman (Wadi Al-Bahayes). The population structure of P. latipinna in Wadi Al-Bahayes (Oman; 23°40′47″N; 58°11′36″E) was studied in June and August 2020, using 124 fish. In the course of this study, the number of individuals of each sex, age, weight and size composition were determined. In addition, the total length–weight relationship (LRW) was calculated, as well as the von Bertalanffy growth equation. The mean growth performance (phi prime) and the condition factor were calculated. Males accounted for 37.10% and females for 62.90% of the population. The length–weight relationship and the von Bertalanffy growth equation were W = 0.0214 × L 2.7889 R2 = 0.9212, Lt = 11.46 (1 − e −0.127 (t + 2.71)) for males and Lt = 14.51 (1 − e−0.072 (t + 3.98)) for females. The mean growth performance and the condition factor were calculated as 1.22 for males and 1.18 for females and 1.54 for all specimens. The study shows that the population of the species is characterized by a wide age range. Consequently, monitoring of this alien species is highly recommended.
