The high market demand for gourami has led to an increase in fish farming activities. However, this fish farming activity is constrained by the spawning and breeding process. Gourami fish takes quite a long time in the seed growth phase so it is feared that it can hamper the fulfillment of gourami fish stocks in the market. Several studies have been conducted to shorten the growth time of fish seeds. One of them is in the field of feed. Modification and alternative feed are expected to contribute to science in the cultivation of gourami fish seeds. The purpose of this study was to determine the effect of feeding additives to increase the growth of carp fry (Osphoronemous gouramy). The research was conducted from August to October 2019 using nets in concrete ponds. The research was conducted experimentally using the group randomized design (RAK) method carried out in 4 treatments and 4 groups. The treatments tested were the provision of additional ingredients consisting of P_1 = 15% Probiotic / Kg feed, P_2 = 0.4% Vitamin C / Kg feed, P_3 = 3% Spirulina/kg feed, P_4 = 3.25% Papain enzyme/kg feed. Observation parameters include absolute length growth, absolute weight growth, survival, and feed conversion ratio. The results showed that 3% spirulina/kg and 3.25% papain enzyme/kg had a significant effect on the rate of weight growth and growth.

This research was conducted at the Aquaculture Laboratory, Faculty of Agriculture, University of Muhammadiyah Palembang. This research used experimental with a completely randomized design (CRD) of 3 treatments and 6 replicates. The feed additives used in this study were P1 (Moringa leaf extract), P2 (Bean sprout extract), and P3 (Lamtoro leaf extract). From observations made for 60 days and sampling every 10 days, the results of observations of tilapia reared with the addition of P1 feed, namely Moringa leaf flour mixed with pellets, showed the highest growth results compared to other treatments. Meanwhile, the lowest growth value was shown by the P3 treatment, namely lamtoro leaf flour mixed with pellets. The conclusion is that the best feed additive for red tilapia growth is the addition of a lamtoro flour mixture.

Belanti village used to be land before the entry of the palm oil company, which caused the canalization to form a lake or swamp. The company's canalization blocked the flow of a natural river in Ulak Pati, Pampangan sub-district, preventing water from flowing and causing it to pool in what was once open land. The result of this canalization caused changes to the ecosystem in the village of Rawa Belanti, which had an impact on the growth factors of aquatic organisms that formed along with the formation of the lake/swamp. This study focuses on collecting data and information about the growth of cork fish that are found in many communities in rawa belanti through the sampling method. The study was conducted for 4 months with sampling intervals every 10 days. Calculation of length-weight and condition factor used all cork fish caught during the sampling.The growth factors assessed were the correlation between length and weight, and the condition factor of the gourami fish caught in the swamp. Based on the results of the study, the correlation of length and weight growth is negative allometric, which means that weight growth is slower than the growth of fish length. Assessment of the condition factor of cork fish shows an average value of 1, which means that the fish is in good body condition. Water quality assessment was also conducted in order to support growth data.

Environmental factors play an important role in the growth and survival of fish, both directly and indirectly. This role is not limited to determining the success of fish growth in terms of length and weight; fish behavior, feeding patterns, and metabolism are also affected. Photoperiod itself is defined as the length of time of light and dark exposure. This study aims to evaluate the effect of photoperiodism on the growth rate and physiological response of red tilapia (Oreochromis niloticus). The study was conducted in Gandus District, Palembang City. Data and analysis were performed using a completely randomized design (CRD) with several parameters such as growth rate, weight gain, survival rate, and behavior of red tilapia observed qualitatively in response to treatment with varying light exposure times. The treatments given were 3 variations of light and dark exposure and 5 repetitions with variations P1: 20 hours of light: 4 hours of dark (20T; 4G) P2: 16 hours of light: 8 hours of dark (16T; 8G), and P3: 12 hours light : 12 hours dark (12T; 12G). The analysis results showed that red tilapia had a positive growth response, characterized by an increase in fish length and weight, caused by increased metabolism due to an increase in feed consumption rate. Fish behavior changed compared to the control group due to physiological stress caused by prolonged exposure to light.
