Abstract “Ocean connectivity” is a dynamic and rapidly evolving field of research in marine science, partly because there is an increasing demand for information on connectivity that informs effective assessment and management of marine resources. Achieving this will require a better alignment between ocean connectivity tools and developments and the needs and challenges of assessments and conservation. For these reasons, the ICES Journal of Marine Science solicited contributions to the article theme set (TS), “Beyond ocean connectivity.” We briefly summarize the nine articles that appear herein, grouping them into four general topics: methodological advances, population dynamics and assessment implications of connectivity, spatial and management implications, and connectivity in ecosystem processes. We also discuss the challenges facing ocean connectivity research if it is to effectively support advancing fisheries assessment frameworks and integrated ecosystem approaches. We hope that the contributions included in this TS serve to convince managers and fisheries scientists of the need to incorporate results from research on connectivity.

Industry Associations

Seafood Industry Australia (SIA) is the national peak body that represents the Australian seafood industry as a whole, including members from wild catch, aquaculture and post-harvest sectors. According to the Australian Institute of Marine Science (AIMS), the fishing and petroleum industries represent a combined contribution to the Australian economy of ~AU$28.5 billion (in 2015–2016) and employ (directly and indirectly) over 55000 Australians.1 At times, our industries’ interests have competed. However, we recognise that we can unlock value for the economy, and those who work in our industries, by finding effective ways to work together. In 2014, a Memorandum of Understanding (MOU) was signed between five commercial fishing and seafood industry associations and APPEA. This MOU committed to the core principles of improved cooperation, open communication and stronger consultation. There is significant benefit for both industries in learning how to improve shared access to marine resources, whether at the early stages of petroleum activities (e.g. seismic) or at the end of an asset’s life (e.g. decommissioning). This presentation will look at efforts to improve relationships between our two industries and make observations about potential ways forward.

Stock Recruitment

Pacific salmon ( Oncorhynchus spp.) populations transfer large quantities of nutrients from their marine to their freshwater habitats. These nutrients have been shown to affect salmon populations in fresh water, including increasing basal food resources and elevating juvenile salmon growth rates and condition. The broader effects on recruitment and commercial harvests, however, are not clear. I developed and explored mathematical models of the effects of these nutrients on stock–recruitment relationships and used these models to investigate management implications. Populations strongly dependent on nutrients had lower sustained yields than those not dependent on nutrients. When nutrients strongly affected the stock–recruitment relationship, relatively low harvest rates and high escapement levels were necessary to maintain the population’s productivity. However, in some scenarios, the highest yields were obtained from small, nutrient-depleted populations. In other scenarios, the nutrient dependence had few management implications.

Abstract The marine resources are waiting for the nation's explorer. Government support and past glory should be a giant step to develop real marine sector support programs. The nations assets supporting facilities and infrastructure of maritime science and technology sector is important to be considered for the efficiency of cost and expenditure of state and the progress of science and technology in the field of Marine.Pra feasibility that has been done, after the formation of Team Work  and the support from  central government collaboration across Ministries and Research Institutions, also supported by government readiness areas within the development of the Indonesia Marine Science and Technology Center (IMSTeP) should be a solid and well-maintained cooperation. The policy issued by the government is required to be able to cover every progress. However whether the policy can be implemented well operationally and substansinya or still need support derivative policies or other bureaucratic obstacles that need to be anticipated to accelerate the progress of this national program so that we soon become Master in his own country in the inner sector in particular ,,,, JalesvevaJayamahe. Abstrak Sumberdaya kelautan yang berlimpah menunggu para explorer anak bangsa untuk bergerak. Dukungan Pemerintah dan kejayaan masa lalu seharusnya menjadi cermin untuk mengembangkan program riil pendukung sektor kelautan khususnya. Aset pendukung sarana dan prasarana iptek sektor kelautan penting untuk diperhatikan demi efisiensi cost dan pengeluaran negara serta kemajuan Iptek di bidang Kelautan.Pra feasibility yang sudah dilakukan, setelah pembentukan Tim Pokja serta dukungan kolaborasi pemerintah pusat lintas Kementerian dan Lembaga Penelitian, di dukung oleh kesiapan pemerintah daerah didalam pengembangan Pusat Iptek Kelautan (IMSTeP) harus menjadi satu kerjasama yang solid dan terpelihara. Kebijakan yang dikeluarkan pemerintah dituntut mampu memayungi setiap progress kemajuannya.Namun apakah kebijakan tersebut dapat terimplementasikan dengan baik secara operasional dan substansinya atau masih perlukah dukungan kebijakan turunannya atau kendala birokrasi lain yang perlu segera di antisipasi untuk mempercepat progress progam nasional ini sehingga dengan segera kita menjadi Tuan di Negeri Sendiri di sektor keluatan khususnya,,,, JalesvevaJayamahe.

Increasing Demand

Marine imaging has evolved from small, narrowly focussed applications to large-scale applications covering areas of several hundred square kilometers or time series covering observation periods of several months. The analysis and interpretation of the accumulating large volume of digital images or videos will continue to challenge the marine science community to keep this process efficient and effective. It is safe to say that any strategy will rely on some software platform supporting manual image and video annotation, either for a direct manual annotation-based analysis or for collecting training data to deploy a machine learning–based approach for (semi-)automatic annotation. This paper describes how computer-assisted manual full-frame image and video annotation is currently performed in marine science and how it can evolve to keep up with the increasing demand for image and video annotation and the growing volume of imaging data. As an example, observations are presented how the image and video annotation tool BIIGLE 2.0 has been used by an international community of more than one thousand users in the last 4 years. In addition, new features and tools are presented to show how BIIGLE 2.0 has evolved over the same time period: video annotation, support for large images in the gigapixel range, machine learning assisted image annotation, improved mobility and affordability, application instance federation and enhanced label tree collaboration. The observations indicate that, despite novel concepts and tools introduced by BIIGLE 2.0, full-frame image and video annotation is still mostly done in the same way as two decades ago, where single users annotated subsets of image collections or single video frames with limited computational support. We encourage researchers to review their protocols for education and annotation, making use of newer technologies and tools to improve the efficiency and effectivity of image and video annotation in marine science.

Over Exploitation

This essay adopts an interdisciplinary approach to consider the meaning of “eco-crime” in the aquatic environment and draws on marine science, the study of criminal law and environmental law, and the criminology of environmental harms. It reviews examples of actions and behaviors of concern, such as offences committed by transnational organized crime and the legal and illegal over-exploitation of marine resources, and it discusses responses related to protection, prosecution and punishment, including proposals for an internationally accepted and enforced law of ecocide. One key element of the policy and practice of ending ecocide is the call to prioritize the adoption of technologies that are benign and renewable. Our essay concludes with a description of the “Almadraba” method of fishing to illustrate that there are ways in which the principles of sustainability and restoration can be applied in an ethical and just way in the context of modern fisheries.
