摘要

亚马逊沼虾(Macrobrachium amazonicum)是一种对水产养殖具有重要意义的淡水虾类,要了解其繁殖潜力,对其繁殖能力进行研究是必要的。因此,本研究旨在评估两种不同饮食对该物种生殖性能的影响,无论是否采用消融程序。试验采用2 × 2因子完全随机设计,采用两种饲料(惰性和新鲜)和两种条件(消融和未消融雌性),每个处理6个重复。在产卵10天后,取出卵并对其整体进行计数。每只雌性获得3个卵,共72个样本。分析了雌鱼的受精率、产卵间隔和增重情况。除体重增加外,所研究的因素之间没有相互作用,其中接受新鲜饲料的消融雌性比未消融的雌性体重增加了三倍。喂食新鲜饲料的雌性比只喂食惰性饲料的雌性(1,084.1个卵)获得更高的生育力(1,373.9个卵)。消融雌鱼产卵间隔缩短1.6天。

Effect of two diets on the fecundity of ablated and non-ablated female of Macrobrachium amazonicum
Macrobrachium amazonicum is a species of freshwater shrimp of great importance for aquaculture and to know its reproductive potential, through the study of its fertility is necessary. Therefore, this study aimed to evaluate the effect of two different diets on the reproductive performance of the species, whether or not adopting the ablation procedure. The experiment was carried out in a completely randomized design in a 2 x 2 factorial arrangement, with two types of feed (inert and fresh) and two conditions (ablated and non-ablated females), using six replicates per treatment. After 10 days of spawning, the eggs were removed and counted in their entirety. For each female, three spawns were obtained, totaling 72 samples. The fertility rate, the interval between spawning and the weight gain of the females were analyzed. There was no interaction between the studied factors, except for weight gain, in which ablated females that received fresh feed gained up to three times more weight than non-ablated females. Females that received fresh feed obtained higher fertility (1,373.9 eggs) than those that received only inert feed (1,084.1 eggs). The interval between spawns was 1.6 days shorter in ablated females.
