Abstract

Vannamei shrimp is a prospective commodity that continues to be cultured intensively in Indonesia. Efforts to produce vannamei shrimp fry are an activity that continues to be developed by stakeholders, including efforts to improve genetics. Apart from a good aquaculture system, genetics is also an important factor in the success of vannamei shrimp culture. This research was conducted at CV. Manunggal Rasa with a research design carried out using a comparison of 2 genetics of vannamei shrimp larvae, namely American Penaeid, Inc (API) and Benchmark Genetics (BM) with a stocking density used of 40,000 individuals/m2 in each pond with an area of 25 m2. Rearing vannamei shrimp fry for 4 cycles provided several differences in the observation of absolute length growth and survival rate. The absolute length growth of the API genetic vannamei shrimp fry was 5.68 mm, while the BM genetics was 6.16 mm. The survival rate in each cycle is cycle 1 (API 89.9% and BM 93.1%), cycle 2 (API 91.4% and BM 95.6%), cycle 3 (API 88.9% and BM 89 .7%) and cycle 4 (API 93.2% and BM 94.6%). The water quality for each cycle is calculated to be optimal, namely ranging from 27-31oC (temperature), 4.5-5 ppm (DO), 30 ppt (salinity), 0-0.1 ppm (ammonia) and 7.9-8.3 (pH).

Abstract

Bumi Dipasena in Tulang Bawang Regency, Lampung Province, was once the largest shrimp farming area in Southeast Asia and played a major role in Indonesia’s shrimp exports. Since the early 2000s, shrimp pond productivity has declined due to institutional conflicts, infrastructure degradation, limited access to capital, and unstable production systems, resulting in reduced household income and economic pressure on local communities. This study aims to identify and analyze household livelihood strategies following the decline of shrimp pond productivity in Bumi Dipasena. The research employs a qualitative descriptive approach based on secondary data, utilizing official statistics, government reports, scientific publications, and credible media sources. Data were analyzed through descriptive qualitative analysis, including data reduction, thematic categorization, and identification of livelihood strategy patterns. The findings show that households respond to the decline by diversifying income into informal sectors, small-scale trade, labor migration, and increased reliance on social networks. These livelihood strategies reflect household-level economic responses to prolonged structural changes after the collapse of shrimp farming as the primary livelihood source. This study contributes to socio-economic and development studies by providing empirical insights into household livelihood reorganization in post-aquaculture decline contexts and offers policy-relevant input for sustainable livelihood support in coastal areas.
