“…Kebutuhan dan ketergantungan akan tercipta dengan sangat baik dengan kesadaran diri untuk saling menjaga usaha dan lingkungan. Pengembangan usaha perikanan harus selaras dengan konsep Ekonomi biru dengan pemanfaatan maksimal sumber daya laut termasuk pengelolaan perikanan tanpa residu yang dapat merusak lingkungan, sehingga dapat meningkatkan penghasilan mata pencaharian dan pekerjaan (Ktari et al, 2022;Liu et al, 2023;Özgit & Zhandildina, 2021).…”

The difficulties and fisheries industry in Indonesia continues to grow in accordance with the 2013–2025 Marine and Fisheries Sector Medium Term Development Plan which refers to the concept of the Blue Economy. The purpose of this research is to find out the implementation of business models and strategies for sustainable sustainability that adopt the Blue Economy concept. This research is a qualitative research using a narrative approach to obtain data related to sustainable strategies in accordance with the Blue Economy concept that can be developed on research objects. The results of the study explain that the success of blue economy-based industries must be supported by a strong commitment between various parties in real action as a form of overall development support, so the direction of program policies must be innovative and creative through a touch of technology. Utilization of digital technology can help fishery businesses based on the concept of a sustainable blue economy, processing all fishery resources owned to be utilized for the welfare of the community without destroying the existing ecosystem. Digital transformation can be a bridge for business owners with markets as consumers, they interact efficiently with each other in meeting the production chain of market needs. Innovation in digital transformation must continue to be carried out and supported by the skills of its human resources to increase attractiveness and expand market access. Keywords: Blue Economy, sustainability, digital transformation.

This review aimed to explain vulnerability and climate change impacts on tropical aquatic fisheries and aquaculture focused on the Asian setting using a systematic literature review. In particular, the present study applied the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) to evaluate the available literature from 1990 to 2020. The study results showed clustering of texts, keywords and titles based on the search terms, e.g. climate, change, fisheries, Asia, adaptation, climate change, fisheries, and aquaculture. Using the text, links with high scores showed the following categorization per cluster: 1) Climate change and food security; 2) Biodiversity and environmental protection; 3) Conservation of resources; 4) Climate change impacts in Asia; 5) Fisheries. While for the abstracts and titles produced the following clustering: 1) Livelihood and food security; 2) Fisheries catch; 3) Approach to stakeholders; 4) Ecosystem services. Climate change or global environmental change dominates vulnerability and adaptation scholarship, but it is only one of the stressors causing vulnerability among fishing and aquaculture sectors. Several studies suggest adaptation as a solution leading to less vulnerability and resilience of fishing communities. However, our findings showed that social and economic factors of climate-induced vulnerability are still relatively neglected. Besides, keeping biodiversity and enhanced environmental protection can lead to a more productive and food-secure environment for farmers and fishers. Therefore, the interventions needed would always lead towards adaptation. Finally, establishing a science-based “adaptive fishery co-management” to further engage with fishing communities by addressing their wider vulnerabilities and aspirations (livelihood needs).

“…Te acoustic properties of marine creatures, including those with swim bladders, have been extensively studied using acoustic techniques like in situ and ex situ TS assessments [24][25][26][27][28]. However, as weak scatterers with variable morphology, jellyfsh still need to be adequately characterized acoustically.…”

The jellyfish Nemopilema nomurai occupies an important position in the Northwest Pacific ecosystem, and monitoring its biomass is necessary to ensure the protection of fishery resources and the safety of offshore industrial production. The acoustic method has been proposed for jellyfish flux estimation and bloom warning, in which the target strength (TS) of the jellyfish is a crucial parameter. However, varied swimming orientations of jellyfish aggregation result in different backscatter strengths. The acoustic echo characteristics in horizontal swimming orientations and multi-frequency broadband signals are yet to be revealed. This study aims to obtain the TS of jellyfish in various orientations and to comprehensively investigate the jellyfish acoustic echo features at various frequency broadband sounds. In an anechoic tank, we used wide-band echosounder and 70 kHz, 120 kHz, and 200 kHz split-beam transducers to measure the TS of jellyfish swimming omnidirectionally. The results show a difference of approximately 4 dB in the jellyfish’s normalized TS at 70 kHz (frequency range: 45 kHz to 95 kHz) and 200 kHz (frequency range: 160 kHz to 260 kHz) center frequency. The normalized TS of jellyfish varies by around 8 dB between horizontal and vertical swimming orientations. For jellyfish swimming horizontally, the TS and bell diameter have the following least squares fits: T S D 70 k H z = 20 log D − 89.36 r 2 = 0.83 ; T S D 200 k H z = 20 log D − 93.85 r 2 = 0.83 . The swimming orientation has significant effects on TS estimation and model construction.
