Analysis of the Effect of Time Difference in Blue Light Illumination on Growth and Behavior in Tilapia (Oreochromis niloticus)

Abstract

Freshwater and marine fish farming faces challenges as the need for tilapia (Oreochromis niloticus) is one of the many fishery commodities, easy to find and widely cultivated in Indonesia. Tilapia can be cultivated in various places such as ponds, reservoirs, rice fields, ponds, rivers and even in waters that have higher salt levels than brackish freshwater. Experimental research experiment design, factorial design (complete randomized design) The experiment carried out in this study was the use of blue light color with different times as many as 3 treatments each repeated 3 times: Treatment A = 10 watt blue light without time change Treatment B = 10 watt blue light with 4 hours Treatment C = 10 watt blue light with 6 hours. Statistical data analysis using the ANOVA test was carried out using the help of the SPSS 16.0 program. The analysis aimed to find out the influence of blue light colour on the behaviour and growth of tilapia seeds. Based on the results of the study, it can be concluded that, Treatment of different irradiation times (0 hours, 4 hours, and 6 hours) has a significant influence on the absolute weight growth of tilapia. Treatment with a 6-hour radiation time per day showed the best weight growth compared to other treatments.
