Abstract

Fish food and feeding play an important role in understanding the rate of growth, development and reproduction in ornamental fish culture.  The current study evaluated the impact of different types of food on the growth of Ornamental fish, Andinoacara pulcher. A comparative analysis of live, prepared, and commercial food was conducted in three feeding groups A, B and C, respectively. For live feed, Artemia larvae were cultured from Artemia seeds, and fed. The growth in terms of weight and body length was measured at 15-day intervals throughout the experimental period of 60 days. In addition, the protein, lipid, ash, and moisture composition of fish were estimated and analyzed.  From the results, the fish fed with live artemia feed attained maximum growth when compared to other prepared feed and commercial feed. The specific growth rate (SGR) was found to be maximum in group A (1.46%), followed by group B (1.15%) and group C (0.71%). There is a well-defined relationship between the rate of growth and the type of food consumed. The protein, carbohydrate, and fat content of fish revealed a higher biochemical composition. In conclusion, the growth and biochemical study in the present investigation indicated that the live feed contains good constituents of vital nutrient substances that promote the growth and protein content of ornamental fish, Blue Acara.
活饵料和营养强化饵料对蓝花楹(Andinoacara pulcher)生长性能和生化成分的潜在影响
鱼食和喂养对了解观赏鱼的生长、发育和繁殖速度起着重要作用。 本研究评估了不同类型的食物对观赏鱼 Andinoacara pulcher 生长的影响。在 A、B 和 C 三个饲养组中分别对活食、配制食物和商业食物进行了比较分析。在活饵料方面,从蒿鱼种子中培养出蒿鱼幼虫并投喂。在 60 天的实验期内,每隔 15 天测量一次体重和体长的生长情况。此外,还对鱼的蛋白质、脂肪、灰分和水分成分进行了估计和分析。 实验结果表明,与其他配制饲料和商业饲料相比,用活蚯蚓饲料喂养的鱼的生长速度最快。A 组的特定生长率(SGR)最高(1.46%),其次是 B 组(1.15%)和 C 组(0.71%)。生长率与摄入的食物种类之间有明确的关系。鱼类的蛋白质、碳水化合物和脂肪含量显示其生化成分较高。总之,本次调查中的生长和生化研究表明,活饲料含有良好的重要营养物质成分,可促进观赏鱼蓝鲫的生长和蛋白质含量。
