The Deepwater Horizon oil spill impacted Louisiana's coastal estuaries physically, chemically, and biologically. To better understand the ecological consequences of this oil spill on Louisiana estuaries, we compared the abundance and size of two Gulf shrimp species (Farfantepeneus aztecus and Litopeneus ...
Integration of grassroots community level data into national planning and development process can improve its efficiency and effectiveness. It will provide timely and continuous data to evaluate investment efforts. It can also foster participatory activities in such a community. We present the idea ...
In this paper a state observer for a distributed parameter system (DPS) with nonconstant parameter functions is presented. The DPS describes the freezing of foodstuff in vertical plate freezers and is a nonlinear heat equation. The observer is based upon the Extended Kalman Filter, meaning that the ...
An inherent link exists between making things and designing things, often relying on skills, knowledge, and tools, and working together to achieve outcomes. Conventional design and manufacture to date has been a closed system requiring professional skills. Traditional manufacture has required a significant ...
A key technology that continues to evolve to meet special requirements of underwater sampling and observation is that of acoustics. This technology is used both actively to ensonify fish, zooplankton, other marine organisms, and the environment, and passively to listen to and record sounds produced ...
This paper introduces the critical success factors framework to develop the application for tuna fishery management. On the previous study, a mentioned framework, consists of four layers: business process layer, information layer, solution layer, and technology layer. Since the framework follows an ...
This paper investigates a signal processing approach of fish abundance estimation in the Sea. There is a high demand for underwater fish estimation due to the increase in current importance of sea fishes. These increase our knowledge about the state of a stock and improve assessment of many commercially ...
Evolution is presumed to proceed by random mutations, which increase an individual’s fitness. Increased fitness produces a higher survival rate for those individuals within populations and drives the variants to fixation over large timescales to produce new species. We recently identified positively ...
Background Microalgae has been concerned as a potential source of biodiesel in the recent years. However, it is costly to harvest microalgae as it is commonly cultured in water and the cells are too small to harvest. In order to reduce the cost of cultivation and harvesting, it is important to improve ...
Background To date, research has shown an increasing use of the term “ecohealth” in literature, but few researchers have explicitly described how it has been used. We investigated a project on health and environmental sanitation (the conceptual framework of which included the pillars of ecohealth) ...
Fishing, farming and ranching provide opportunities for predators to prey on resources concentrated by humans, a behavior termed depredation. In the Gulf of Alaska, observations of sperm whales depredating on fish caught on demersal longline gear dates back to the 1970s, with reported incidents increasing ...
Testis-specific protein kinase 1 (Tesk1) is a serine/threonine kinase with unique structural features. In the present study, we cloned and characterized the tesk1 gene of tongue sole, Cynoglossus semilaevis. The full-length tesk1 cDNA consists of 1,672 nucleotides, encoding a 331 amino acid polypeptide ...
Coho salmon (Oncorhynchus kisutch) transgenic for growth hormone (GH) show substantially faster growth than wild-type (WT) fish. We fed GH-transgenic salmon either to satiation (1 year; TF) or the same smaller ration of wild-type fish (2 years; TR), resulting in groups matched for body size to WT salmon. ...
The purpose of this study was to determine if the set of genomic regions inferred as accounting for the majority of genetic variation in quantitative traits remain stable over multiple generations of selection. The data set contained phenotypes for five generations of broiler chicken for body weight, ...
Traceability system is one of the most critical requirements in logistic information systems and the supply chain risk management for both global food safety and quality assurance. Realtime documentation from the earlier stages of production process enabled the two way process of traceability. This ...
