Abstract

Nile tilapia (Oreochromis niloticus) is an important freshwater aquaculture species whose morphometric characteristics provide essential insights into growth performance and sexual dimorphism in cultured populations. This study aimed to analyze the morphometric traits of male and female Nile tilapia reared in grow-out ponds at the Freshwater Aquaculture Center (PBIAT) of Politeknik Negeri Nusa Utara. Thirty fish were sampled using simple random sampling, and eleven morphometric parameters were measured alongside water quality observations to evaluate the suitability of the rearing environment. The results showed significant differences in several morphometric traits, including total length, standard length, body length, head length, body height, snout length, and caudal peduncle height, all of which were higher in males, with average body weight also greater in males (257.75 g) than females (205.15 g). Water quality parameters remained within optimal ranges for tilapia culture throughout the study period. The study concludes that male tilapia exhibit superior morphometric performance compared to females, indicating their potential advantages for selective breeding and improved grow-out production, and recommends further research involving larger populations and genetic evaluation to strengthen the use of morphometric indicators in tilapia aquaculture.

Abstract

Indonesia's high biodiversity has great potential to be developed in various fields, including fisheries. To support sustainable and environmentally friendly aquaculture activities, the utilization of local natural resources is one of the keys to increasing the competitiveness of the national fisheries sector amid global challenges related to food security and the environment. One alternative source that can be used as a natural feed supplement in fish farming is from the Curcuma genus, such as white turmeric (Curcuma mangga Val). Therefore, the purpose of this study was to determine the effectiveness of white turmeric extract (Curcuma mangga Val) on the growth of tilapia. The research design used was a completely randomized design consisting of 3 treatments and 3 replicates, namely: Treatment A (feed without turmeric extract), Treatment B (feed added with 5 ml of white turmeric extract), and Treatment C (feed added with 10 ml of white turmeric extract). Feed was administered three times daily at a dose of 5% of body weight. The results showed that the addition of white turmeric extract (Curcuma mangga Val.) significantly increased the growth of Nile tilapia (Oreochromis niloticus). The most effective treatment dose was Treatment C (10 ml/kg of feed), which resulted in an absolute average increase of 8.99 g in weight and 2.67 cm in length.
