A shortage of seeds and low-quality production of the marine algae Kappaphycus alvarezii are classic problems that farmers encounter. Therefore, growth hormones, a natural ingredient in young coconut water, must be used. This research aimed to analyze the growth rate of the marine algae K.alvarezii using coconut water immersion treatment at different times (0 minutes, 30 minutes, 40 minutes, and 50 minutes) with an initial weight of 50 g. This research was conducted in South Sulawesi, Wakatobi Regency, Wangi-Wangi Selatan District, Liya One Melangka Village from June to October 2023. This research used the RAL method to measure the weight of the marine algae Kappaphycus alvarezii every 10 days and measure water quality for 40 days. The results of the ANOVA analysis in the soaking treatment of K.alvarezii sea algae seeds showed significant effects

Koi (Cyprinus rubrofuscus) is one of the freshwater fish farming commodities that has an attractive color. Cultivators are trying to improve the quality of the color of this fish by adding a source of pigment. One is Spirulina, a source of natural pigments added to feed. Spirulina platensis has a content of B-carotene (28%) and Zeaxanthin (17%). This study aims to enrich Daphnia sp by using S.platensis flour to increase koi fish's color brightness and growth. This research was carried out for ±40 days at the Tatelu Freshwater Aquaculture Fisheries Center (BPBAT) Tatelu. The research method is experimental by applying a Complete Random Design (CRD) consisting of four treatments and three replicates. Treatment A (Control), B (3 g/L), C (5 g/L), D (7 g/L) S.platensis flour. The test fish used were 96 koi carp seeds with a length of 57 mm and a body weight of 5.47 g. The containers used are 12 aquariums measuring 30×40×40 cm3 with a volume of 48 L and fish stocking density of 8 fish. The data analysis used was Analysis of Variance, and a further test of the Smallest Real Difference (BNT) was carried out using the SPSS version 26.0 application. The results showed that the application of Daphnia sp enriched with S.platensis flour could have a real effect on the color brightness and specific growth rate of koi carp (p<0.05). The best treatment in this study was the administration of S.platensis flour as much as 7 g/L.

Color is one of the reasons ornamental fish are in demand by the community, so farmers need to maintain the color of ornamental fish. This study aims to determine the effect of carrot juice on the color of goldfish. This research was conducted from December to January 2023. The method used was an experimental method with Complete Randomized Design (RAL) with four treatments and three repeats in each test group. Testing is carried out by giving feed with a mixture of carrot juice with different doses. The results showed that the color values in goldfish were different, namely, P0 treatment without giving carrot juice with a color value of 18.54, P1 treatment (10 g/100 ml aquades) with a color value of 18.4, P2 treatment (20 g/100 ml) with a color value of 19.35, P3 treatment (30 g/100 ml) with a color value of 17.67. Analysis of Variance (ANOVA) showed that the effect of carrot juice on the color of goldfish had no significant effect on each treatment with FHitung (0.11) > FTabel (4.07). Water quality parameters during the study were still in normal conditions for the growth of goldfish.

Tilapia is a fish species in Indonesia with significant economic value. Tilapia cultivation has excellent prospects, both domestically and internationally, requiring effective measures to ensure production meets community standards. The prospects for developing tilapia cultivation are quite promising, as the low production costs of tilapia farming allow for higher profits. Biofloc technology is an alternative solution to the waste problem of intensive farming. This technology is highly advantageous because it not only reduces inorganic nitrogen waste from leftover feed and feces, but also provides supplemental protein feed for farmed animals, thereby increasing growth and feed efficiency.This study aims to analyze the benefits and factors that influence the success of tilapia biofloc cultivation in SikoFish Gorontalo. This study uses a quantitative method with data collection techniques through surveys and observations. The results of the study indicate that tilapia biofloc cultivation can generate profits of Rp. 180,585,000 / harvest with a return on investment of 1.14 years. Factors that influence the success of tilapia biofloc cultivation are location selection, container preparation, media preparation, seed preparation, seed distribution, feed management, water quality management, and floc density. Therefore, it is necessary to develop business and production cost efficiency to increase income and make tilapia biofloc cultivation viable.

Feed is very important in the development of fish farming because around 70% of fish farming production costs come from providing feed. To support the growth and brightness of the color of koi carp, it is necessary to have nutritional content and β-carotene according to the fish's needs. Feed that meets the nutritional needs of fish can increase the growth and color brightness of koi carp. This research aims to determine the effect of feed doses containing shrimp head meal, carrot flour and red spinach flour on the growth and color brightness of koi carp.This study aims to determine the effect of feed doses containing shrimp head meal, carrot flour and red spinach flour on the growth and brightness level of koi goldfish. This research was carried out from November to December 2022 at the Tatelu Freshwater Aquaculture Fisheries Center (BPBAT). The method used was an experimental method with a completely randomized design (CRD) consisting of 4 treatments and 3 replications. Treatment A = (control giving 5% feed dose without containing shrimp head meal, carrot flour and red spinach flour) treatments B, C, and D (feeding containing shrimp head meal, carrot flour and red spinach flour dose 5%, 10 % and 15%). In order to find out the results of the influence of feeding containing shrimp head waste flour, carrot flour and red spinach flour, the data obtained includes the results of calculating the level of color brightness and growth in koi fish calculated using analysis of variance (ANOVA)Based on the results of the study, absolute length growth in treatment D with a dose of 15% had a very significant effect with a value of 1.56 cm, while for the brightness of the color in treatment C, with a dose of 10%, it had a very significant effect with an average value of 10.69, while the growth weight and survival of koi goldfish were not significantly different.
