Tantangan pengembangan ekonomi biru di Lombok adalah menurunnya habitat terutama rumput laut, terumbu karang dan bakau, karena tingginya tekanan ekonomi yang menyebabkan orang terlibat dalam eksploitasi sumber daya  perikanan. Tujuan riset adalah mereview penerapan konsep “Ekonomi Biru” pada usaha perikanan budidaya  di Kabupaten Lombok Timur. Data dan informasi dikumpulkan melalui penelusuran dokumen, laporan riset dan publikasi ilmiah terkait topik kajian. Dokumen-dokumen tersebut dianalisis secara konten (content analysis) dan direview dari aspek sosial dan ekonomi yang dijelaskan secara kualitatif. Hasil review menunjukkan bahwa 6 (enam) usaha perikanan dapat memberikan efek berganda yaitu budidaya  lobster, budi daya  rumput laut, pengolahan kepiting, pengolahan limbah kepala ikan, dan tambak garam mempunyai peluang menciptakan efek berganda, artinya keenam usaha tersebut dapat menciptakan alternatif mata pencaharian yang bisa berdampak pada peningkatan ekonomi rumah tangga. Title: Prospects of the Implementation of Blue Economy Concept on An opportunity Fisheries Bussiness in East Lombok DistrictThe challenge of developing a blue economy in Lombok is the decline of habitats, especially seaweed, coral reefs and mangroves, due to the high economic pressure that causes people to be involved in exploitation of fisheries resources. The aim of the research is to review the application of the concept of “Blue Economy” in aquaculture businesses in East Lombok District. Data and information were collected through documents investigation, research reports and scientific publications related to the topic of the study. These documents were analyzed using content analysis and reviewed from the social and economic aspects qualitatively described. The result shows that the review indicates that 6 (six) fisheries businesses can provide multiple effects namely lobster aquaculture, seaweed farming, crab processing, fish head waste treatment, and salt farming have the opportunity to create multiple effects, meaning that the six businesses can create alternative livelihoods that can has an impact on improving the household economy.

With the commercial fishery expansion to deeper waters, some vulnerable deep-sea species have been increasingly captured. To reduce the fishing impacts on these species, exploitation and management must be based on detailed and precise information about their biology. The common mora Mora moro has become the main deep-sea species caught by longliners in the Northeast Atlantic at depths between 600 and 1200 m. In the Azores, landings have more than doubled from the early 2000s to recent years. Despite its growing importance, its life history and population structure are poorly understood, and the current stock status has not been assessed. To better determine its distribution, biology, and long-term changes in abundance and size composition, this study analyzed a fishery-dependent and survey time series from the Azores. M. moro was found on mud and rock bottoms at depths below 300 m. A larger–deeper trend was observed, and females were larger and more abundant than males. The reproductive season took place from August to February. Abundance indices and mean sizes in the catch were marked by changes in fishing fleet operational behavior. M. moro is considered vulnerable to overfishing because it exhibits a long life span, a large size, slow growth, and a low natural mortality.

Abstract The changes in abundance and biodiversity of deep-sea fish fauna are described based on an annual deep-water longline survey with data collected during the period 2015–2019 in the Basque Country continental Slope (ICES Division 8c). The sampling scheme included hauls in four 400 m strata, from 650–2250 m deep. The DST sensors installed in the main line have allowed us to set an accurate soak time for each haul, and they were used to calculate fishing effort and CPUE by haul. The catchability of the fishing gear indicated that 15% of the total hooks deployed in the five-year period were able to fish, and that the bottom longline was very effective in fishing a wide number of different species in all depth ranges. The fishing gear caught 14 different species of sharks (13 deepwater and one pelagic), two chimaeras and nine teleosts. The abundance and biomass registered on the hooks attached to the bottom were between three and four times higher than in the floating sections, and the highest CPUE and biomass were recorded between 1051–1450 m, from 2015 to 2017, and in the 1451–1850 m strata, but they do not show any clear trend throughout the five years of the series.
