This research aims to determine water quality analysis in different cultivation systems for tilapia (Orecromis niloticus) cultivation. This research was carried out in May 2024 at the Andalas Fish Seed Center, Gorontalo City. Method: This data was obtained from the results of measurements in the Bioflok pond, which is a holding pond for Tilapia fish (Oreocromis niloticus) and the Beton pond, which is a pond for rearing Tilapia fish seeds (Oreocromis niloticus), where measurements of pH, DO and temperature are carried out every 6 hours and on measurements. Table media is used in data processing to differentiate between one result and another. Based on the research results, it shows that the cultivation system using biofloc ponds is more effective in converting ammonia compounds into nitrate compounds and maintaining the water quality of the tilapia cultivation media. Water quality greatly influences the growth and survival of farmed fish, where biofloc ponds with more controlled water quality can increase the growth and survival of farmed fish.

The freshwater lobster (Cherax quadricarinatus) is a precious commodity within the freshwater aquaculture sector. It is essential to investigate the effects of different natural feeds on lobster growth to enhance aquaculture practices. This study aimed to identify the types of natural feed that influence and improve freshwater lobster juveniles' growth and survival rate. This study was conducted from January to February 2024 at the Kasih Karunia Suwawa Aquaculture Hatchery. A Completely Randomized Design (CRD) was applied, with four treatment groups: Treatment A (bean sprouts), Treatment B (Tubifex sp.), Treatment C (tofu residue), and Treatment D (a combination of bean sprouts, Tubifex sp., and tofu residue). The feed was administered daily at 7% of the total biomass, with a feeding frequency of twice per day. Data were analyzed using ANOVA with SPSS software. The observed parameters included length growth, weight growth, survival rate, and moulting frequency. The results showed that Treatment B (Tubifex sp.) yielded the best growth and moulting frequency, with length growth at 0.76 cm, weight growth at 0.70 g, and moulting frequency at 0.67. The highest survival rate, at 96.67%, was observed in Treatment D (bean sprouts + Tubifex sp. + tofu residue). ANOVA results indicated that different types of natural feeds did not significantly impact the growth and survival of freshwater lobsters.

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.

Catfish (Clarias sp.) waste, which includes bones, skin, and scales, represents a potential natural source of collagen with significa nt economic value. Collagen plays an important role in pharmaceuti cal, cosmetic, and functional food industries due to its bioactive proper ties such as antioxidant, antimicrobial, and tissue-regenerative capabil ities. This literature review aims to explore the potential utilization of catfish waste as a collagen source and its possible combination with bioactive plants, such as Moringa oleifera, Hibiscus sabdariffa, or mic roalgae, to enhance biological activity & formulation stability. The rev iew indicates that acid & enzymatic extraction methods are the most eff ective techniques for obtaining high-quality collagen from catfish was te. Recent studies reveal that catfish collagen possesses an ami no acid composition similar to mammalian collagen, with high levels of glycine & proline. Furthermore, combining catfish collagen with bio active pla nt extracts enhances antioxidant & antidiabetic properties. This study highlights that collagen development from catfish was teoffe rs an inno vative, eco-friendly biotechnological approach aligned with circular economy principles & great potential for value prod uct development.

This study was conducted to analyze the effect of probiotic application in water media on the growth and survival of vannamei shrimp. It also aimed to determine the optimal probiotic dosage for enhancing growth and survival. The research was carried out for 45 days using a Completely Randomized Design (CRD). The treatments included different probiotic dosages: Treatment A = addition of Lactobacillus sp. at 2.0 ml/L, Treatment B = 2.5 ml/L, and Treatment C = 3.0 ml/L. Data were analyzed using ANOVA through the SPSS application. The observed parameters during the study included length growth, weight gain, and survival rate. Based on probiotic bacteria testing conducted at the Microbiology Laboratory, Faculty of Mathematics and Natural Sciences, Universitas Negeri Gorontalo (UNG), the probiotic developed through fermentation showed bacterial growth identified as Lactobacillus, with a total colony count of 1.23 × 10⁸ CFU/ml. The results indicated that Treatment C (Lactobacillus sp. 3.0 ml/L) provided the best growth performance, with weight gain of 0.23 g and length growth of 1.02 cm. Meanwhile, the highest survival rate was found in Treatment B (Lactobacillus sp. 2.5 ml/L), at 54%. According to the ANOVA results, different probiotic dosages of Lactobacillus sp. had a significant effect on length growth but showed no significant effect on weight gain and survival of vannamei shrimp. Keywords: Vannamei shrimp, Lactobacillus sp., growth, survival rate Abstrak.
