“…Fresh fish is a highly perishable product due to its high water activity, nutrient availability, nearly neutral-pH (factors that influence microbial growth) and the presence of autolytic enzymes; hence, it is susceptible to post-harvest losses [8,9]. Under normal refrigerated storage conditions, its shelf-life is limited by the development of enzymatic (caused by endogenous or microbial enzymes) and chemical reactions [10].…”

Fresh fish is extensively consumed and is one of the most-traded food commodities in the world. Conventional preservation technologies include vacuum and modified atmosphere packaging, but they are costly since requires capital investment. In the last decade, research has been directed towards the development of antimicrobial packaging systems, as an economical alternative to these. This paper outlines antimicrobial films and coatings applied so far on fresh fish, their efficacy against targeted microorganism/group and effects on chemical quality of the product. Findings show that edible films/coatings incorporated with different active agents applied to fresh fish are able to inhibit the microbial growth and decrease the rate of fish nutrients degradation, thus preventing the formation of chemical metabolites; a shelf-life extension of 6 to 13 days was obtained for fish fillets, depending on the species on which the active packaging materials were applied. The manufacturing use of these formulations could lead to a significant reduction in fish waste, consequently, a diminution of economic losses for fish traders and retailers. Therefore, their industrial production and commercialization could be an exploitable sector by the packaging industry.

“…To avoid such a scenario, Cinner (2011) proposed changes that need to occur, for instance, strengthening fisheries management strategies. Postharvest losses are rarely considered when formulating fisheries management strategies worldwide (Tesfay andTeferi 2017, see Njock et al 2009 for an exception). Although the research project did not incorporate an explicit fisheries management focus, the learning generated on how to develop and implement communication for social change innovations in a fisheries context could be drawn upon to help integrate postharvest losses into a broader, more gender-aware fisheries management strategy.…”

The Barotse Floodplain fishery is an important source of livelihood for economically poor women and men in western Zambia. Current efforts by the Department of Fisheries and the traditional authority to manage the fishery can be characterized as weak. The use of unsustainable fishing practices and overfishing are pervasive. Drawing on resilience thinking, we examine the extent to which the existing fishery-dependent livelihood context represents a social-ecological trap, i.e., a process in which rigid and persistent behavioral responses are applied because of a lack of capacity to adapt, leading to overdependence on the fishery, and ultimately, unsustainable outcomes. We use a gender lens and look beyond the primary sector (fishing) to include considerations of a secondary sector (postharvest fish processing) as an important dimension in the social-ecological trap paradigm. We present findings from an empirical research project that tested improved fish processing technologies and a communication for social change innovation as an alternate way to view a possible escape pathway from the trap not commonly recognized in the literature. The results suggest that there is value in adapting the social-ecological trap thinking to include postharvest fish losses and unequal gender relations as drivers of the trap in the floodplain fishery, and that approaches that combine technical innovation to reduce losses with social innovation to improve gender relations may hold promise for enabling fishery-dependent people to shift pathways out of social-ecological traps.

This study aims to: (1) identify the types of home industry products based on marine fishery, and (2) to determine marine fishery products that can be developed as regional leading products. Four sub-districts of coastal areas of Tanah Laut regency were chosen purposeful as study locations, namely Kurau, Jorong, Panyipatan and Takisung. Primary data collection was conducted through survey and interview to sample of marine fishery product home industry which was taken by simple random sampling. Selection of marine fisheries home industry superior product using Analytic Hierarchy Process (AHP) technique. The result of analysis showed that the home industries in the coastal area of Tanah Laut Regency is dominated by simple technology with the products produced in the form of traditional products, such as salted fish, fish and shrimp crackers, and “amplang” crackers, dried shrimp, shrimp paste, fish floss. The leading product alternatives of marine fisheries home industries in Tanah Laut regency are determined based on the criteria of raw material availability, raw material quality, value added product, technological mastery level, market opportunity, labor absorption, and current industrial product development condition shows that cracker product selected fish as a product that can be seeded with a total value of 0.245, the next shrimp crackers and fish/shrimp floss each with a total value of 0.221 and 0.152. Penelitian ini bertujuan untuk: (1) mengidentifikasi jenis-jenis produk industri rumah tangga berbasis perikanan laut, dan (2) menentukan olahan perikanan laut yang dapat dikembangkan sebagai produk unggulan daerah. Empat kecamatan wilayah pesisir Kabupaten Tanah Laut dipilih secara sengaja sebagai lokasi studi yaitu Kurau, Jorong, Panyipatan dan Takisung. Pengumpulan data primer dilakukan melalui survey dan wawancara terhadap sampel industri rumah tangga hasil perikanan laut yang diambil secara acak sederhana. Pemilihan produk unggulan industri rumah tangga perikanan laut menggunakan teknik Analytic Hierarchy Process (AHP). Hasil analisis menunjukkan bahwa industri rumah tangga di wilayah pesisir Kabupaten Tanah Laut didominasi industri berteknologi sederhana dengan jenis produk yang dihasilkan berupa produk tradisional, seperti ikan asin, kerupuk ikan, kerupuk udang, udang kering, terasi, amplang dan abon ikan/udang. Alternatif produk unggulan industri rumah tangga hasil perikanan laut Kabupaten Tanah Laut yang ditentukan berdasarkan kriteria ketersediaan bahan baku, mutu bahan baku, nilai tambah produk, tingkat penguasaan teknologi, peluang pasar, serapan tenaga kerja, dan kondisi pengembangan produk industri saat ini menunjukkan bahwa produk kerupuk ikan terpilih sebagai produk yang dapat diunggulkan dengan nilai total 0,245, berikutnya kerupuk udang dan abon ikan masing-masing dengan nilai total 0,221 dan 0,152 .
