Mahseer being the most important freshwater fish that contributes to the major fisheries activity of the rivers in the world. In Malaysia, Mahseer is an important indigenous freshwater fish because of their market value. However, the number of this freshwater fish declining from day to day due to the ...
A sustainable management for the mangroves has not only provided consistent yield of renewable forest wood products such as timbers that are utilized for firewood, poles for foundation, construction materials, fishing gear and even tannin extraction, but also fishery resources and conductive environment ...
It is well known that human activities, such as harvesting, have had major direct effects on marine ecosystems. However, it is far less acknowledged that human activities in the surroundings might have important effects on marine systems. There is growing evidence suggesting that major reorganization ...
In this paper, we propose a GIS plotter for small fishing vessels, with the objective of promoting effective coastal fishing and the sustainable use of aquatic resources in coastal fishing. Currently, various marine charts are created in support of coastal fishing operations. However, the charts are ...
The relationship between marine lives is manifested by certain aspects of the marine food chain, which are composed of a number of tropic structures. And the marine food web consists of number of intricate interlacing food chain. Because of its complexity, traditional quantitative theory is not efficient, ...
This work focuses on presenting a new efficiency Acoustic Frequency IDentification system in the hope of improving underwater monitoring. Earth is a water planet as ocean's covers about two-thirds of the earth surface. Such extension remains unexploited to satisfy humans' needs. Recently, attempts grow ...
The adverse effects of prenatal mercury exposure, most commonly resulting from maternal fish consumption, have been detected at very low exposure levels. The omega-3 fatty acids found in fish, however, have been shown to support fetal brain and vision development. Using data from a prospective, cohort ...
Many data sets exist that contain both geospatial and temporal elements, in addition to the core data that requires analysis. Within such data sets, it can be difficult to determine how the data have changed over spatial and temporal ranges. In this design study we present a system for dynamically exploring ...
Maritime domain awareness is important for coastal nations in terms of applications to coastal conservancy, security, fishery and stewardship of their exclusive economic zones (EEZs). Maritime situational awareness involves knowing the location, speed and bearing of ships and boats in the EEZ. HF radar ...
Malaysian Geographical or Geospatial Health (MyGeoHealth) is a term used to describe innovative method for monitoring environmental risk factors on human health. There are possible spatial relationship between environment and cholera outbreaks in Tawau, Sabah due to the recent outbreaks are hard to ...
Abstract In today's drilling environments and economics oil companies demand focus on all aspects of services delivered by the oil field service companies. Safety and efficiency are paramount with cost considerations following closely behind. Reductions of non-productive time are continuously monitored ...
Effective underwater communication can be carried out when the masking effect of underwater ambient noise is reduced. The main objective of this paper is to develop an optimum adaptive algorithm for accurate detection of the underwater acoustic signal buried due to the effect of ambient noises in the ...
Estuaries are ecologically and economically valuable and have been highly degraded from both land and sea. Estuarine habitats in the coastal zone are under pressure from a range of human activities. In the United States and elsewhere, very few conservation plans focused on estuaries are regional in ...
Tsetse flies are notoriously difficult to observe in nature, particularly when populations densities are low. It is therefore difficult to observe them on their hosts in nature; hence their vertebrate species can very often only be determined indirectly by analysis of their gut contents. This knowledge ...
Divergent natural selection rooted in differential resource use can generate and maintain intraspecific eco-morphological divergence (i.e., resource polymorphism), ultimately leading to population splitting and speciation. Differing bottom environments create lake habitats with different benthos communities, ...
In 1948, a small colony of emperor penguins Aptenodytes forsteri was discovered breeding on Emperor Island (67° 51′ 52″ S, 68° 42′ 20″ W), in the Dion Islands, close to the West Antarctic Peninsula (Stonehouse 1952). When discovered, the colony comprised approximately 150 breeding pairs; these numbers ...
Background We examine the potential prognostic and predictive roles of EGFR variant III mutation, EGFR gene copy number (GCN), human papillomavirus (HPV) infection, c-MET and p16INK4A protein expression in recurrent or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN). Methods We ...
Thesafety characteristics of feed used in fish and crustacean aquaculture systems are an essential tool to assure the productivity of those animal exploitations. Safety of feed may be affected by different hazards, including biological and chemical groups. The aim of this preliminary study was to evaluate ...
In previous studies, we have demonstrated that the population structure of the bloom-forming cyanobacterium Microcystis aeruginosa is clonal. Expanded multilocus sequence typing analysis of M. aeruginosa using 412 isolates identified five intraspecific lineages suggested to be panmictic while maintaining ...
