Off the Ningaloo coast of North West Western Australia, Spangled Emperor Lethrinus nebulosus are among the most highly targeted recreational fish species. The Ningaloo Reef Marine Park comprises an area of 4,566 km2 of which 34% is protected from fishing by 18 no-take sanctuary zones ranging in size ...
In response to concerns over excessive discarding from Australian recreational round traps (with four funnel entrances) used to target giant mud crabs, Scylla serrata, an experiment was done to assess the independent and cumulative utility of paired, bottom-located horizontal escape gaps (46×120 mm) ...
Background The annual fish Nothobranchius furzeri is characterized by a natural dichromatism with yellow-tailed and red-tailed male individuals. These differences are due to different distributions of xanthophores and erythrophores in the two morphs. Previous crossing studies have showed that dichromatism ...
Fatty acids (FA) have recently been used in several studies to infer the diet in a number of species. While these studies have been largely successful, most have dealt with predators that have a fairly specialized diet. In this paper, we used FA analysis as a tool to infer the diet of the nearctic river ...
This paper reports some tests conducted on a new magnetic device for the reduction of fuel consumption and pollutant emissions, installed onboard an Italian trawler since March 2013 and tested in laboratory in May 2014. The electromagnetic field generated by the device operates as a fuel treatment to ...
The trend of biomimetic underwater robots has emerged as a search for an alternative to traditional propeller-driven underwater vehicles. The drive of this trend, as in any other areas of bioinspired and biomimetic robotics, is the belief that exploiting solutions that evolution has already optimized ...
Over the last two decades, zebrafish (Danio rerio) have emerged as an efficient model to aid in the research of a broad range of human diseases as well as such diverse applications as environmental modelling and drug discovery. Economically, the large number, low price and low maintenance requirements ...
Bioultrasonics (BUS), a new concept of combining bioelectricity and ultrasonic (US) technology is demonstrated in this work. A feasibility study of the BUS stimulation for aquaculture fish was conducted and a higher survival rate of several fishes from the BUS-stimulated group was obtained. The BUS ...
This paper focuses on the development of closed greenhouse concepts and application of that technology to aqua-ponics systems. At first, aquaponics systems and closed greenhouses with TES are described. Then, TES in abandoned mines are discussed. Finally, ongoing research on aquaponics systems at the ...
Dredging is the process of removing sediments from the seabed to deepen the waters for the safe navigation of vessels. The dislodged materials from the seabed, i.e. dredged marine soils, are generally disposed of as a geowaste. This paper examines the potential reuse of the dredged materials within ...
Effects of six different pesticides on the growth of Chlorella vulgaris were investigated in this paper. The results showed that when the chlorella were cultured in the media with carbendazim, procymidone, thiram, tebuconazole, prochloraz and fludioxonil repectively, lower concentrations(<;1mg/L) ...
Lack of good inter-organization development methodology often leads to failure in establishment of interoperability platforms needed for streamlining operations among government agencies. To overcome the challenge, this paper proposes a collaborative methodology and management approach that emphasizes ...
This paper describes a novel framework to segment elongated strips of marine oil spill based on a cooperative model. We construct a higher-order energy function which characterizes data consistency and smoothness of varying orders in an integrated framework. We model the data consistency in terms of ...
We demonstrate the performance of optical fibre dissolved oxygen (DO) sensor when subject to different core material and sizes. It was found that fluorescence emission from oxygen sensitive material coated at the end-face of an optical fibre DO sensor varies with core material and sizes. Glass core ...
The data-link layer protocol is of great significance for the effectiveness and reliability of the transmission. In terrestrial wireless networks, there are three error control protocols in data-link layer, stop-wait ARQ, go-back-N ARQ and selective ARQ. Moreover, LT code, an advanced error control ...
This paper presents an overview of this field of research, outlines some of the opportunities available to add value to fishery by-product streams alongside some of our most recent studies and data in this area. In Atlantic Canada around 418 000 tonnes per year waste is produced at fish processing plants. ...
Oil and gas operations have moved from conventional petroleum reserves to unconventional petroleum reserves such as remote offshore, deep Ocean and the Arctic. The management of oil spills is especially challenging due to these conditions. Oil spills are typically due to vessels accidents, tanker discharges, ...
Recently, the need for offshore aquaculture has become increasingly important in raising migratory fish species, such as, tuna and mackerel, in an offshore environment. Moreover, offshore fish cages are located 2-5 km offshore with water depths ranging from 40 to 100 m. Hence, visiting the fish cages ...
This paper presents a thorough approach characterizing the transit efficiency of a hybrid-driven underwater glider (HDUG) with a foldable propeller. A kind of HDUG with a folding propulsion mechanism has been designed in this paper. The HDUG features high efficiency penetrating in ocean like conventional ...
This paper describes the outcomes of a TechSurge sponsored by the Marine Technology Society focused on ocean sensors. Specific goals of the meeting were (1) provide a forum for the exchange of information related to ocean sensors and their role in long-term, autonomous operation; (2) assess ocean observing ...
