Abstract

Grouper fish, particularly the brown-marbled grouper (Epinephelus fuscoguttatus), are among the most economically significant marine species widely farmed and exported. This study aimed to analyze the growth performance and business analysis of the production of brown-marbled grouper, both in nursery and grow-out segments. The research was conducted using a case study method at a governmental production and research center located in Lampung Province, Indonesia. Primary data were collected through field observations, while secondary data were obtained from interviews with farm personnel. The study revealed that the nursery phase faced significant challenges, with larval survival rates as low as 4.2%. In contrast, survival rates improved considerably in larger fish, demonstrating better resilience as they grow (reaching 92-93%). From a business perspective, the grow-out activity was found to be more profitable due to lower investment costs. However, it requires a longer period to raise the fish to market size. Both nursery and grow-out operations proved to be profitable, with respective R/C ratios of 1.6-2.0. Overall, while grouper farming is economically viable, it requires careful management to overcome the high mortality in the early life stages and to optimize the investment cost-effectiveness of the nursery phase.

Abstract

Golden Denisoni (Sahyadria denisonii) is one of the most valuable freshwater ornamental fish commodities with strong prospects in the international niche market. This species is widely demanded due to its attractive coloration, premium mutation strains, and limited number of consistent producers. This writing was developed based on interview notes with Mr. Wisnu, the manager of a golden denisoni farming business located in Bogor Regency, West Java. Information was collected through direct discussions regarding the history of the business, breeding and rearing activities, market demand, operational resources, cost components, and constraints faced during cultivation. The results indicate that the largest demand comes from export markets, particularly China, where buyers seek high-quality clear fish for ornamental trade. The selling price of clear 2-inch golden denisoni ranges from IDR 20,000 to 25,000 per individual, reflecting the high economic value of this commodity. Key farming activities include mutation breeding, juvenile rearing, daily water exchange, and intensive aeration to prevent ammonia accumulation and maintain dissolved oxygen levels. Major challenges encountered in production are fungal infections, environmental stress, and fish mortality caused by human error in farm monitoring. The collected information was structured using the business model canvas framework, covering customer segments, value propositions, distribution channels, customer relationships, key activities, key resources, partnerships, cost structure, and revenue streams. Overall, golden denisoni farming demonstrates significant profitability potential as a premium ornamental aquaculture business. Sustainable growth of this sector requires consistent water quality management, improved operational control, and strengthened market partnerships to ensure stable production and continuous export supply.

Abstract

Aquaculture is a rapidly growing food production sector that plays a vital role in national food security. This study aims to analyze the business model of a Pangasius nursery farm located in Pasir Gaok, Rancabungur District, Bogor Regency, using the Business Model Canvas (BMC) framework. A qualitative descriptive approach was employed, with primary data collected through semi-structured interviews, field observations, and documentation. The results indicate that the Pangasius nursery farm serves local collectors, market traders, and individual buyers, offering consistent fish quality and stable pricing. Feed constitutes the largest cost component, while revenue is mainly derived from the sale of fingerlings. The discussion highlights that business success depends on cost efficiency, effective technical management, and partnerships with research institutions that foster innovation and sustainability in aquaculture enterprises.

Abstract

Cangkring Village has various fishery resources, including ponds, fishponds, and access to waters that support fish farming. The Lecturer Returning Home Program aims to disseminate innovations in systems and appropriate technologies for integrated grouper fish farming through survey and training activities. This study used a survey method combined with a descriptive approach. Sampling was carried out using purposive sampling to collect data from fish farmers in Cangkring Village. The survey research was conducted to identify and analyze the potential for grouper (Epinephelus sp.) nursery and rearing based on natural resources in Cangkring Village, Indramayu. Field observations, questionnaires, and interviews were used to collect data. The recommended stocking density is around 32 fish/m3 for grouper fish rearing in KJT measuring 3×6×1 m for an initial weight of 100‒200 g, and 1,500‒2,000 fish/m3 for grouper seeds in KJT measuring 1.5×1.0×0.5 m to 2.5×1.25×0.8 m. Trash fish have great potential for the development of grouper fish breeding in tanks and ponds as well as rearing in floating net cages/floating net cages (KJT) in the estuary waters of the Cimanuk River, Cangkring Village. In addition, the coastal waters and estuaries of Cangkring Village are rich in rebon shrimp, with an abundance of around 900‒1800 fish/L. The larger the fish seeds, the lower the stocking density. This community empowerment activity is an alternative for the community to improve education and skills in fish farming which can later increase income through an integrated system of grouper nursery and rearing based on natural resources.

Abstract

The nursery phase of hybrid grouper (kerapu cantang; Epinephelus fuscoguttatus x Epinephelus lanceolatus) farming is a crucial business segment, as it serves as a key link in the seed supply chain for grow-out operations. This study aims to analyze the profitability aspects of nursery operations at a commercial farm in Indonesia, using a trading enterprise (UD) in Situbondo, East Java, as a model. The research was conducted by collecting both primary and secondary data through interviews. Observations revealed an average fish survival rate of 86.5%, resulting in an estimated annual production of 99,000 fingerlings using a total of 14 nursery tanks measuring 4x3x1 m³ each. The largest investment cost components were the nursery tanks (40%) and water installation systems (33%). The main fixed and variable cost components were employee salaries (69%) and feed (84%), respectively. Financially, the nursery operation is profitable, generating an annual profit of IDR 274,338,923 and an R/C ratio of 1.59. The investment payback period is estimated at 1.68 years (20 months). Optimization of operations is recommended through production scale-up in the second year, by reducing feed costs, or by increasing the fry production.

Abstract

Biofloc technology (BFT) relies on the management of microbial communities to improve water quality and recycle nutrients in aquaculture systems. This review summarizes findings from 16 studies that analyzed prokaryotic (bacterial) communities in biofloc systems using different carbon sources, categorized by structural complexity: (i) simple (glucose, molasses), (ii) mid-complex (starch), and (iii) complex (digested plant cellulose, wheat bran). Dominant phyla commonly found across all carbon categories include Proteobacteria, Bacteroidota/Bacteroidetes, Actinobacteriota, Cyanobacteria, Firmicutes, and Planctomycota/Planctomycetes. Unique phyla associated with simple carbon were Chlamydiae, Acidobacteriota, Dadabacteria, Patescibacteria, and Xanthomonadaceae, while Fusobacteria dan Gemmatimonadetes appeared only in systems using mid-complex and complex carbon sources. Chloroflexi appeared in all carbon categories but was more frequently mentioned in studies when systems using mid-complex and complex carbon sources. These results suggest differences in substrate utilization, respiratory pathways, and bacterial groups involved in degrading carbon of varying complexity. However, quantitative comparisons of bacterial communities could not be made due to variations in C:N ratios, carbon dosages, and cultured species among studies. A more standardized approach is needed to better understand how carbon complexity shapes the structure and function of microbial communities in biofloc systems.
