Abstract:

This paper examines the economic effects of management policies on four of the seven beach-seine net fishing operations in False Bay. The effects of past regulations are examined by assessing whether or not this industry is at present profitable. It was found that under the present management policies all fishing crews are profitable. A new policy preventing fishermen from catching white steenbras has been introduced. This was examined and it was shown that only one of the crews examined would be effected. Two proposed policies were examined to determine their impact on the sector. The first p

Abstract:

The aim of this work was to investigate the production of antimicrobial compounds by marine epiphytic bacteria. This work was carried out by devising a "niche mimic bioreactor", in which physical and chemical conditions were similar to the original ecological niche from which the bacteria were isolated. A modified roller bottle bioreactor was designed to mimic the intertidal environment and could facilitate the production of antimicrobial compounds by two marine isolates. Biofilm formation by these bacteria was found to be the key requirement for this observation. An Air- Membrane Surface (AMS

Abstract:

Like all intertidal species, the barnacle Balanus glandula must cope with temperature and desiccation stress during daily low tide exposure. The increase in temperature at low tide leads to both increased metabolic rate and the potential for increased ATP demand. With its additional inhibition of oxygen intake, low tide thus has an energetic cost that is often reflected in an increase in oxygen consumption following resubmersion. As anthropogenically induced global climate change increases air and water temperatures, its cost might increase. B. glandula individuals were exposed to 4‑hour low t

Abstract:

The removal of marine species through fishing has impacted marine ecosystems for thousands of years. The pressure of exploitation on marine ecosystems has now reached a point at which there is serious concern over ecosystem well-being on a global scale. There has, therefore, been a global move towards an ecosystem approach to fisheries management. The objective of this study was to develop a decision tree framework to assess the status of exploited marine ecosystems, which could be successfully applied to numerous ecosystems and guide decision support under changing conditions.

Three case studies of “cold water species” were selected (Argentina sphyraena, Micromesistius poutassou and Merluccius merluccius) and, in each case, various biological traits – including the factors regulating early oogenesis, reproductive tactics, physical condition, parasitism and energy allocation trade-offs – were examined.

The condition of the herring (Clupea harengus) in the Baltic Sea has decreased during the past 30-40 years. This decrease could be explained by different factors; (1) change in diet due to changes in zooplankton community, (2) changes in water temperature and salinity, (3) increasing nutrient inputs and (4) competition for food with other species such as sprat (Sprattus sprattus). In this study the change in condition was analysed using the Fulton’s condition index, and by looking at age and sex of the fish as well as the season and locationthe fish was caught, the differences between these fa

The ability of corals to build reefs can be attributed to their relationship with single-celled algae of the familySymbiodiniaceae.Through the process of photosynthesis, these algae can provide their coral hosts with over 90% of their daily energy requirements.

However, over time, the coral will select a dominant symbiont speciesthat can depend on the local environment. Until this study, the size or age of the coral at which this transition from multiple

Marine Renewable Energy (MRE) is a promising source of energy for the future. However, it is still under development and many challenges need to be overcome to develop competitive solutions.

Because of these criteria, MRE mooring systems require novel mooring systems and associated standards. MRE mooring standards need to take into account the highly dynamic behaviour of these system

Abstract:

Recent research has suggested that the build-up of a Diffusion Boundary Layer (DBL) around the coral’s tissue can potentially create a buffer to ocean acidification and oxygen depletion. However, to date few studies have investigated the DBL’s potential role in supporting corals’ calcification and highlighted contrasting results. In this study I analysed pH and oxygen dynamics within the DBL of two populations of the reef-building corals A. tenuis, M. digitata and P. damicornis, originating from two sites with markedly different flow regimes, under a combination of slow/fast flow and ambient/l

In this study, we collected Taiwanese LL fishery data and environment variables during the period of 1980–2005. The principal component analysis (PCA) and wavelet analysis were used to investigate the relationship between LL catch data of YFT and oceanic environmental factors. The results were summarized as below: In the Indian Ocean, YFT is one of th

Abstract:

Human intervention plays a critical role in the maintenance operations of marine systems. Consequently human factors are identified as one of the main causes of accidents in marine systems especially during maintenance operations. Characterisation and assessments of human factors in the form of Human Reliability Assessment (HRA) is an important step to better understand accident causation during maintenance operations. This would help minimize human errors and enhance overall safety and reliability of the marine systems. The International Maritime Organization (IMO) recommends implementing HRA

In this study, we collected the Taiwanese LL data and environment variables during the period of 1998-2008. The Generalized Additive Models (GAM) was used to explore the correlation between LL catch data of swordfish and oceanic environmental factors. We then use the predict modes of GAM to predict the fishing grounds of swordfish. High nominal catch per unit effort (CPUE) areas are concentrated in the northwestern an

Abstract:

<div>Biodiversity loss is the silent crisis of the 21st century. Human activities are drastically altering the diversity of life on Earth, yet the extent of this transformation is shrouded by our limited information on biodiversity and how it is changing. Emerging technologies may be suited to fill this information gap, and as a result increase our capacity to measure and manage natural systems. Acoustic monitoring is a remote sensing technique that is rapidly reshaping the temporal and spatial scales with which we can assess animal biodiversity. Through recording and analyzing soundscapes—the

Abstract:

The role of seagrass systems, including those of Zostera muelleri, in providing critical ecosystem services including provision of nursery habitat for economically important fish species and significant nutrient cycling services are well known (Orth et al., 2006). The current understanding of the population ecology of the species is however lacking, potentially leading to management decisions that fail to incorporate the ability of Z. muelleri to disperse, recruit and grow as well as the role the species plays in the development of microphytobenthic communities within seagrass systems.
