One of the fishery commodities included in the leading fishery commodity is the sea cucumber (Holothuroidea sp.). Sea cucumber is a target for anglers' catches because it has high economic value and can be easily marketed, not only on a local scale but also for export. The increased demand for sea cucumber exports can threaten the sustainability of sea cucumber resources in nature. This is due to the effect of fulfilling market demand directly related to fishing efforts by fishers. Responding to these problems, the purpose of this study was to analyze the fishing season and the supply chain of sea cucumbers on Sapuka Island, Pangkep Regency, South Sulawesi Province. The research methods used are the survey, observation, and Participatory Rural Approach (PRA). There were 20 PRA participants, including 10 sea cucumber fishers, 2 village government officials, 3 community members, 2 community groups (POKMAS), and 3 sea cucumber collectors. The data that has been collected is then analyzed using MDS using the Rapfish approach. The results showed that the sea cucumber fishing season on Sapuka Island was throughout the year January-December, with the highest fishing season in January-April. There are 5 models/patterns in the sea cucumber supply chain on Sapuka Island, namely the sea cucumber flow; 1) Sapuka Island fishermen-exporters in Makassar, 2) fishermen-collectors in Makassar-exporters in Makassar, 3) fishermen-collectors in Galesong-Exporters in Makassar, 4) fishermen-Sapuka Island collectors-Exporters in Makassar, 5) fishermen-collectors of Sapuka-collectors of Galesong-Exporters in Makassar.

Red Tilapia is one of the freshwater fish favored by the community because of its delicious and savory taste and economic value. This study aimed to determine the best effect between stocking density and water discharge on the growth and survival rate of Red Tilapia (Oreochromis niloticus) cultured using by recirculation aquaculture system (RAS). The method used in this study was a factorial 2-factor Completely Randomized Design (CRD). Where the first factor is stocking density with a treatment level of P1 = 1 fish/liter of water, P2 = 4 fish/liter of water, P3= 7 fish/liter of water, and the second factor is water discharge with a treatment level of D1 = 30 ml/second, D2= 40 ml/second, D3= 50 ml/second. The observed variables included growth (total length and total weight) and survival rate (SR). The highest full-length yield was 3.9 cm in the P2D3 treatment (stocking density of 4 birds/liter and 50 ml/second). The highest absolute weight yield was 6.41 grams in the P2D3 treatment (stocking density of 4 fish/liter, water discharge 50 ml/second). Meanwhile, the highest survival rate was 98.15% in the P1D3 treatment (stocking density of 1 fish/liter, water discharge 50 ml/second). The results showed that the interaction between different stocking densities and water discharge did not significantly affect the growth and survival rate of Red Tilapia Fcount < Ftable

HABs is a term that describes the species of harmful phytoplankton found in the waters. One of the factors triggering its development is the increase in the concentration of nutrient types nitrogen (N) and Posfor (P) is very high. To that end, a study aimed at detecting potentially dangerous types of phytoplankton (HABs) in a water has been conducted in May-July 2021. The waters in question are the coastal waters of the southern part of Makassar (JB) and the coastal waters of Takalar (coastal waters beba = BB, Boddia = BG, and Sanrobone = SB). The waters are waters located on the western coast of the southern part of South Sulawesi.  Enumeration of HABs is performed on samples of water that has been filtered using net plankton. The results showed that as many as 10 potential genera of HABs have been found. The genera in question are Bacteriastrum, Chaetoceros, Nitzschia, and Pseudo-nitzchia of the Bacillariophyceae group, and Ceratium, Dinophysis, Gymnodinium, Peridinium, Prorocentrum, and Protoperidinium of the Dynophycea group. From the results of the proportion test, potentially HABs were found to be lower at about 30.13% when compared to the non-HABs phytoplankton group of about 69.87% based on spatial, and 30.57% versus 69.43% based on temporal.

This research aims to discover the effect of probiotics applications on the production revenue and cost efficiency of catfish culture. This research shows that the application of probiotics on the catfish feed can decrease the amount of FCR value, in which the value of FCR with probiotics is 0.96 within 1.11 without probiotics. This result shows that the best productivity of catfish was obtained by application of probiotics with productivity of 8.4 kg/m², and R/C Ratio 1.35. Moreover productivity of catfish culture without probiotics application is 7.3 kg/m² and R/C Ratio 1.18. Then the value of productivity based on unit costs produces a value of Rp. 11,176, - while for ponds without the addition of probiotics in the feed of Rp. 12,709, -Production values costs that must be incurred by farmers to produce 1 kg of catfish are lower in aquaculture that uses feed with probiotics so that profits will increase. These results suggested that the farmers can optimizing the use of probiotics to increase feed efficiency from the catfish rearing business without adding other inputs.
