<p>The current linear use of plastic products follows a take, make and waste process. Commonly used by large scale industries, including the commercial fishing industry, this process results in approximately 8 million tonnes of plastic entering the ocean every year. While the fishing industry supplies livelihoods, a valuable food source and financial capital to millions of people worldwide, it’s also a significant contributor to the ocean plastics crisis. Without effective recycling schemes, an estimated 640,000 tonnes of plastic fishing gear is abandoned, lost or discarded within the ocean every year. New Zealand is no exception to this problem, as China’s waste import ban, as well as a lack of local recycling infrastructures, has resulted in the country’s commercial fishing gear polluting local coastlines as well as islands in the pacific. With the only other option for the plastic fishing gear being landfill, there is a critical need for circular initiatives that upcycle used plastic fishing gear locally into eco-innovative designs.  This research examines the issue by investigating how used buoys, aquaculture ropes and fishing nets from New Zealand’s fishing company ‘Sanford’ may be upcycled into eco-innovative designs through distributed manufacturing technologies. It introduces the idea of the circular economy, where plastic fishing gear can be reused within a technical cycle and explores how 3D printing could be part of the solution as it provides local initiatives, low material and energy usage and customisation. Overall, the research follows the research through design based on design criteria approach. Where materials, designs and systems are created under the refined research criteria, to ensure the plastic fishing gear samples are upcycled effectively into eco-innovative designs through 3D printing.  The tangible outputs of this research demonstrate how a circular upcycling system that uses distributed manufacturing technologies can create eco-innovative designs and provide a responsible disposal scheme for plastic fishing gear. It provides a new and more sustainable waste management scheme that could be applied to a range of plastic waste streams and diverts materials from entering the environment by continuously reusing them within the economy.</p>

Lake Baikal is the largest fresh water reservoir of our planet and a unique natural site included in the UNESCO World Heritage List. Meanwhile, Baikal is not only Russia’s largest freshwater fishing reservoir. Large-scale commercial fishing started here at the beginning of the 19th century and, with small breaks caused by bans imposed on industrial fishing due to depletion of valuable commercial fishery species stock, continued until October 2017, when once again restrictions in the fishing industry were imposed. One of the reasons for this was the increasing of the illegal unreported and unregulated fishing which led to depletion of harvestable stock of omul. However, these restrictions neither eliminated extensive unreported fishing, nor solved the problem of rapid fish stock rebuilding in the unique lake. Using methods of mathematical analysis and modeling this article examines factors facilitating breach of law in the fishing industry and unreported fishing for Baikal omul. The article provides a brief characteristic of the Baikal oldest Malomorsky fishing area as well as an eco-economic assessment of the possibility to rebuild the fishing stock within this water zone taking into account the increasing tourist flow in the Baikal region.

<p>This research is focused towards the use of large-scale FDM 3D printing within the automotive industry, specifically to design a bespoke habitable sleeping environment attached to a Range Rover Sport. 3D printing has risen as a viable form of manufacturing in comparison with conventional methods. Allowing the designer to capitalise on digital data, enabling specific tailored designs to any vehicle model. This thesis asks the question “Can design use the properties of digital vehicle data in conjunction with large-scale FDM 3D printing to sustainably produce bespoke habitable sleeping environments for an automotive context?” Further to this, FDM 3D printing at a large-scale has so far not been explored extensively within the automotive industry.  FDM 3D printing is an emerging technology that possesses the ability to revolutionise the automotive industry, through expansion of functionality, customisation and aesthetic that is currently limited by traditional manufacturing methods.

This thesis takes advantage of the digitisation of the automotive industry through 3D modelling and renders as a design and development tool.   This project explored a variety of methods to demonstrate a vision of a 3D printed habitable sleeping environment. The primary methodologies employed in this research project are Research for Design (RfD) and Research through Design (RtD). These methodologies work in conjunction to combine design theory and practice as a genuine method of inquiry. The combination of theory and design practice has ensued in the concepts being analysed, reflected and discussed according to a reflective analysis design approach. The design solution resulted in an innovative and luxury bespoke habitable sleeping space to be FDM 3D printed. Through the use of digitisation, the sleeping capsule was cohesively tailored to the unique design language of the Range Rover Sport. This thesis resulted in various final outputs including a 1:1 digital model, high quality renders, accompanied by small scale prototypes, photographs and sketch models.</p>

This chapter analyses the campaign to expand the Pacific Remote Islands Marine National Monument, which was first created by President George W. Bush in 2009 and then expanded by President Barack Obama in 2014 to 1,270,000 km2. It argues that the remoteness of the monument, and the minimal commercial activity occurring within it, provided environmental groups with considerable influence in lobbying for ambitious protections. The chapter goes on to explain that the commercial fishing industry was largely unsuccessful in its efforts to limit and scale back protections for the monument. Its inability to demonstrate high interest salience in the region weakened its bargaining position with the Obama White House, thereby paving the way for stricter conservation measures.

Glass Eels

Abstract European eel Anguilla anguilla recruitment into the rivers of the northeastern Atlantic has declined substantially since the 1980s. Monitoring of recruiting juveniles, or glass eels, is usually undertaken in small estuaries and rivers. Sampling of large-scale estuaries is rare, due to the size of the sampling area and the resources needed to provide adequate sampling levels. Here we describe surveys for glass eels in the UK’s largest estuarine system, the Severn Estuary/Bristol Channel. We sampled across a 20 km-wide stretch of the estuary in 2012 and 2013, using a small-meshed net deployed from a commercial fishing trawler, and the surveys yielded over 2500 glass eels. Eels were more abundant in the surface layer (0–1.4 m depth) than at depth (down to 8.4 m depth), were more abundant close to the south shore than along the north shore or middle of the estuary, and were more abundant in lower salinity water. Numbers were higher in the second year than in the first and eels were more abundant in February than April. The difficulties and logistics of sampling in such a large estuary are discussed, along with the level of resources required to provide robust estimates of glass eel abundance.

AbstractThroughout its European history, Australia has solved recurrent labor shortages by importing workers from overseas. Situated on shipping lanes between the Pacific and Indian Oceans, the northern Australian pearlshelling industry became a significant locus of second-wave transnational labor flows (1870–1940) and by the 1880s was dependent on indentured workers from the Pacific and Southeast Asia. Exempted from the racially discriminatory Immigration Restriction Act of 1901, indentured Asian seamen, principally Japanese, maintained the industry until the outbreak of the Pacific War in 1941. The Torres Strait pearlshelling industry, centered on Thursday Island in Far North Queensland, resumed in 1946 amid general agreement that the Japanese must not return. Nevertheless, in 1958, 162 Okinawan pearling indents arrived on Thursday Island in a controversial attempt to restore the industry's declining fortunes. This article is intended as a contribution to the history of transnational labor movements. It consults a range of sources to document this “Okinawan experiment,” the last large-scale importation of indentured Asian labor into Australia. It examines Australian Commonwealth-state tensions in formulating and adopting national labor policy; disputes among Queensland policy makers; the social characteristics of the Okinawan cohort; and local Indigenous reactions. Also discussed are the economics of labor in the final years of the Torres Strait pearling industry. This study thus extends our knowledge of transnational labor movements and the intersection of early postwar Australian-Asian relations with Queensland Indigenous labor policy. It also foreshadows contemporary Indigenous demands for control of local marine resources.

Bottom Contact

Bottom longline hook and trap fishing gear can potentially damage sensitive benthic areas (SBAs) in the ocean; however, the large-scale risks to these habitats are poorly understood because of the difficulties in mapping SBAs and in measuring the bottom-contact area of longline gear. In this paper, we describe a collaborative academic–industry–government approach to obtaining direct presence–absence data for SBAs and to measuring gear interactions with seafloor habitats via a novel deepwater trap camera and motion-sensing systems on commercial longline traps for sablefish (Anoplopoma fimbria) within SGaan Kinghlas – Bowie Seamount Marine Protected Area. We obtained direct presence–absence observations of cold-water corals (Alcyonacea, Antipatharia, Pennatulacea, Stylasteridae) and sponges (Hexactinellida, Demospongiae) at 92 locations over three commercial fishing trips. Video, accelerometer, and depth sensor data were used to estimate a mean bottom footprint of 53 m2 for a standard sablefish trap, which translates to 3200 m2 (95% CI = 2400–3900 m2) for a 60-trap commercial sablefish longline set. Our successful collaboration demonstrates how research partnerships with commercial fisheries have potential for massive improvements in the quantity and quality of data needed for conducting SBA risk assessments over large spatial and temporal scales.
