Abstract

The snubnose pompano (Trachinotus blochii), which is an introduced fish, is currently in increasing demand, both for the domestic market (Jakarta and other big cities) and international markets such as Singapore, Taiwan, Hong Kong, and China. The snubnose pompano can be cultivated in ponds because it is tolerant to changes in salinity (5-40 ppt). In this study, the use of lights installed in cages used to maintain the snubnose pompano nursery will be responded to natural food that is positively phototactic (zooplankton, shrimp, and small fish species) which will gather as feed at night. So, it is hoped that the use of these organisms as an alternative feed source can increase feed efficiency. The urgency of this research is to determine efforts to save on the use of artificial feed and to suppress parasite attacks. A t-test was carried out to compare the averages of two different samples, on the growth rate and health of snubnose pompano fish. Research using lights resulted in optimum growth of snubnose pompano with 100% survival rate, feed conversion ratio (FCR) value of 0.9 and produced snubnose pompano size 80–100 g/head within two months as well as healthy fish seeds. With indicators of parasitic attack that are lower than the treatment without light with a prevalence value of 25% (with lights); range of 25%-75% (without lights) and intensity 6-8 (with lights); range 11-35.67 (without light). The snubnose pompano seeds are always actively moving when the light is on, the use of the light can effectively catch organisms such as small shrimp or small crustaceans so that the snubnose pompano seeds can be used to be digested as an alternative food (as observed in the stomach contents and intestines of the snubnose pompano). The light also indicates that parasitic attacks on the snubnose pompano are less common.

Abstract

The aquaculture of Anguilla bicollor has significant economic potential, but persistent challenges continue to hinder profitability for farmers. Two of the most pressing issues are low dissolved oxygen levels and poor feed conversion efficiency. These problems slow eel growth and drive-up operational costs, creating a bottleneck for sustainable production. This study examines a combined strategy to tackle these challenges by integrating probiotics (Lactobacillus sp.) and paddlewheel aeration. Research was conducted at BLUPPB Karawang, using 600 juvenile eels in ponds subjected to four distinct treatments: (1) probiotics and paddlewheels together, (2) paddlewheels-only, (3) probiotics-only, and (4) a control group with no intervention. Over a 45-day period, survival rates (SR), relative growth rates (RGR), and feed conversion ratios (FCR) were carefully monitored. The findings were promising. Ponds that used both probiotics and paddlewheels achieved the best results: an RGR of 1.19%, an SR of 100%, and an FCR of 1.09. Probiotics contributed to better gut health and digestion, while the paddlewheels boosted water oxygenation—creating an ideal growth environment. While no direct interaction between the two methods was observed, their combined application proved highly effective in improving productivity and sustainability. This integrated approach offers a practical solution to some of the most significant challenges in Anguilla bicollor aquaculture.
