Abstract

Feed was the most important part in aquaculture. Not only affecting growth, but the feed also impacted the cultivation environment. Poor feeding management in the use of feed will have a negative impact on the cultivation process. The purpose of the research was to create a dynamic system model. In the model a systemized algorithm was structured that would assist cultivators in carrying out aquaculture activities and with this model, problems that occurred were immediately resolved. The dynamic system model was the method used in this research. This model was used to determine the optimization of feed use based on several variables that support the process of using the feed. In this research, the production of Oreochromis niloticus was 14 kg, the amount of feed used was 10 kg, which affects the increase in the amount of organic matter, which was 3626.4 g (total feces + uneaten feed) in 65 days cultivation period. The result showed that the total feed was connected with organic waste, namely total N, total P, total feces, and total uneaten feed. The results obtained from this research were then poured into a dynamic system and the results were found, namely the relationship between feeding and organic waste, namely linear or perpendicular. The design of this dynamic system model was expected to enable tilapia cultivators to develop aquaculture businesses that were more environmentally friendly, effective, and efficient.

动态系统方法对罗非鱼(Oreochromis niloticus)养殖影响的研究
饲料是水产养殖的重要组成部分。饲料不仅影响生长,还影响养殖环境。饲料使用中的饲养管理不善会对养殖过程产生负面影响。研究的目的是建立一个动态的系统模型。在该模型中,构建了一个系统化的算法,该算法将帮助养殖者开展水产养殖活动,并且使用该模型可以立即解决发生的问题。本研究采用的方法是动态系统模型。该模型用于根据支持饲料使用过程的几个变量确定饲料使用的优化。本研究中,尼罗褐口鱼产量为14 kg,饲料用量为10 kg,影响了有机质的增加,在65 d的培养期内,有机质的增加量为3626.4 g(总粪便+未食用饲料)。结果表明,总饲料与有机废物有关,即全氮、全磷、总粪便和总未吃饲料。然后将本研究得到的结果倒入一个动态系统中,得到结果,即投料与有机废物之间的关系,即线性关系或垂直关系。这一动态系统模型的设计有望使罗非鱼养殖者能够发展更环保、更有效和更高效的水产养殖业务。
