Feeding ecology of piscivorous brown trout was studied in the Pasvik watercourse, Norway and Russia. The watercourse is heavily regulated for hydroelectric purposes, and 5000 brown trout > 25 cm are stocked annually to compensate the negative impacts of the impoundments. Stocked and wild trout had almost identical diets consisting mainly of vendace Coregonus albula and partly of whitefish Coregonus ...

Barents Sea ecosystem is limited. Due to the information available on benthos the Ecopath model of Sørfjord, Northern Norway, was used to investigate possible trophic changes with introduction of king crab to the model. A literature study of the king crab was conducted to find information on diet, mortality, consumption rate and other life history parameters required by the model. A short ...

Controlling the expansion of capture capacity has been a major challenge for the fisheries management systems around the North Atlantic. Despite focused attempts to reduce this capacity in recent years in different jurisdictions, it has continued to expand. This chapter uses a case study of changes in Norwegian fisheries to help explain why this has happened. The article supports the replacement of ...

In the period 2001-2004 four bottom trawl surveys were carried out in the Gulf of Tonkin to investigate the aquatic stocks in the Vietnamese sector (67,370km2). The Gulf has tropical characteristics and great diversity of commercial species, but lately fishing pressure seems to have grown excessively. The swept-area cruises followed a stratified random design, with a fixed station grid imposed ...

The small-scale fishery is a traditional activity and enrolled in social and cultural practices of the coastal communities and some places of the inland waters of Mozambique. This activity is one of the largest sources of income and employment. In 1990, Mozambique adopted the market economy and since 1992, the State begun a progressive liberalisation of financial institutions. At the same time, ...

The Shallow Water Shrimp fishery is the most important fishing activity in the Mozambican fishing industry. The shrimp resources along the Mozambican coast are concentrated in the Maputo Bay, Limpopo River mouth and Sofala Bank. Sofala Bank is the most important fishing area with around 50.000 Km2. Three main fleets exploit the shrimp resources, namely, artisanal, semi-industrial and industrial. ...

This multidisciplinary analysis of Namibia marine aquaculture developments has found it to have a good potential. Existing Namibian aquaculture laws are comprehensive in nature controlling aspects such as water, land, public health, sanitation and disease, however they ignore fish welfare. Mean temperature of Namibian marine coastal waters in the150 m water depth strata has averaged at 14.07 oC for ...

Mucus samples were collected from five different farmed Atlantic salmon (Salmo salar) and Atlantic cod (Gadus morhua) in order to study the content of antibacterial activity in the mucus and to compare the activity of mucus samples of the two different fish species. The mucus samples were diluted in buffer, desalted and adjusted to different protein concentrations in the mucus samples, A search ...

The paper is devoted to consideration of main aspects of internationalization process of the firm. The international marketing literature and findings of previous studies in the area construct theoretical framework for the conceptual model, worked out for the purposes of current research. Empirical study investigates motives for entering the Russian seafood market, perceived barriers and choice of ...

This thesis examines the effectiveness of the co-management approach in the fishery management system of Uganda with specific case reference to the implementation of the Beach Management Units (BMU), an institutional structure for the co-management approach, in the Lake Kyoga and Lake Victoria fishing villages. The theoretical frame work of this thesis involves looking at the concept of co-management, ...
