Decline in Fish Stock and Livelihood of Small-Scale Fisheries in Shores of Lake Victoria, Tanzania

Fisheries sustainability is categorised through four conceptual pillars: ecological, economic, and social, including cultural and institutional. Much work on fisheries sustainability has been done in marine fisheries relative to inland fisheries. Two inland peri-urban impoundments, Chivero and Manyame in Zimbabwe, support numerous small-scale fisheries; however, environmental and socioeconomic variables threaten the sustainability of the fisheries. This study aimed to identify and contextualise drivers and barriers to sustainability of small-scale fisheries in these two peri-urban impoundments. We applied three frameworks, Fishery Performance Indicators, Community-Based Fishery Indicators and FAO Small-Scale Fisheries Indicators, to identify and contextualise the drivers and barriers. Quantitative and qualitative methods were used to collect data from fishers in the two impoundments. A structured questionnaire was administered to 115 fishers in 23 fishing companies operating in the two lakes. Fisheries income and revenue as well as food security are key drivers. Lack of post-harvest equipment, volatile fish markets, water quality and quantity deterioration and fish stock decreases are key barriers to sustainability of fisheries in the two impoundments. There are subtle differences in the extent and impact of the drivers and barriers of fisheries sustainability in the two lakes. The differences relate to the uniqueness of the aquatic habitats, social constructs and fisheries operational frameworks in each lake. This suggests a need to assess fisheries sustainability using an integrated bottom-up approach starting from individual fisheries < community fisheries < global/generic fisheries.

ABSTRACT Fish stock in marine is dynamic due to fluctuation in the annual total catch. Consequently, the estimate number of fish stock changes yearly, without exception in the coastal of Cilacap District. This current study was intended to reassess the condition of fish stock utilization in the coastal water of Cilacap in 2012. Data of fish production, effort, fish price, and effort cost in 1999-2012 are taken from the Office of Fisheries Agency of Cilacap District. Analysis of fish stock condition is carried out using Gordon-Schaefer bioeconomic model. The results showed that utilization of marine fish resource in the coastal water of Cilacap District was in the condition of over fishing both in terms of MSY or MEY.Key words: fish stock assessment, Gordon-Schaefer model, small scale of fisheries------- ABSTRAK Stok sumberdaya ikan di suatu perairan laut selalu dinamis karena jumlah penangkapan ikan berubah setiap tahunnya. Konsekuensinya adalah bahwa dugaan stok ikan di suatu lokasi perairan juga berubah setiap tahunnya, tidak terkecuali di perairan pantai selatan Kabupaten Cilacap Provinsi Jawa Tengah. Penelitian ini bertujuan untuk menduga status tingkat pemanfaatan stok udang oleh nelayan skala kecil di perairan pesisir Kabupaten Cilacap dengan tahun acuan 2012. Data produksi udang, data upaya penangkapan, data harga udang, dan data biaya per upaya penangkapan tahun 1999-2012 bersumber dari Dinas Kelautan dan Perikanan Kabupaten Cilacap. Analisis kondisi tingkat pemanfaatan stok ikan dilakukan menggunakan model keseimbangan bioekonomi Gordon-Schaefer. Hasil penelitian menunjukkan bahwa pemanfaatan sumberdaya ikan laut di wilayah pesisir Kabupaten Cilacap telah berada pada kondisi lebih tangkap (overfishing) baik dari segi MSY maupun MEY.Kata kunci: pendugaan stok ikan, model Gordon-Schaefer, nelayan skala kecil

New Evidence

Aquaculture is instrumental for increasing global fish production, but its ecological effects can create new pressures on the fishing grounds that small-scale fisheries (SSFs) depend on. As a result, achievement of SDGs 1 (end poverty) and 2 (end hunger) in societies of the Global South is compromised, and that of SDG14 (sustainable marine resources) is complicated. Using new evidence from Lake Victoria, which harbors Africa’s largest inland SSFs and a fast-growing aquaculture industry, this chapter examines how science, technology, and innovation (STI) can support ecologically and socially sustainable governance of fisheries resources. The author argues that a sustainable expansion of aquaculture needs to protect the natural resources that small fishers depend on while maximizing their ability to benefit from fish-farming. STI-based solutions, if integrated in a transformation governance approach, can secure and expand contributions from capture fisheries and aquaculture to help achieve SDGs 1, 2, and 14. The concept of transformation governance is based on a threefold structure: to increase eco-efficiency, redistribute access to natural resources, and recognize eco-sufficiency as a guiding principle. By applying this threefold resource-governance approach, the potential for STI-based solutions to provide greater overall eco-efficiency is utilized, restrictions on total resource use prevent rebound effects, and the principle of redistribution promotes a focus on appropriate technologies for small-scale resource users.
