Although Nui Chua National Park MPA is considered as an effective MPA of Vietnam, especially in the involvement of community in management process, an overall assessment of biodiversity, socioeconomic and governance could help managers continue developing the advantages and overcome mistakes. By using relevant indicators, this study stated that abundance of species is somewhat increased, the ...

In the present study, a hedonic model was used to estimate price increments or discount of catfish (Pangasius sp.) due to quality attributes in a domestic market named Natunbazar in Barishal district of Bangladesh. Using price and attribute data obtained by a questionnaire survey from the Barishal Natunbazar fish market, a linear hedonic price model was estimated which includes both continuous ...

Hovedmålet med denne oppgaven har vært å fastslå sammensetningen av lipider og aminosyrer, i tillegg til vann og askeinnhold i blåskjell og kamskjell (Mytilus edulis og Pecten maximus). Evnen til å hemme angiotensin converterende enzym (ACE) ble også undersøkt. I tillegg ble det undersøkt hvilken effekt to ulike typer tilberedning hadde på de ulike faktorene. Resultatene viste en tydelig forskjell ...

Salttilsetning (NaCl) har vært benyttet i lang tid i næringsmiddelindustrien både for å forbedre sensoriske egenskaper og for å konservere matvarer. Inntak av salt er imidlertid generelt for høyt i den vestlige verden, også i Norge. Det er nå vel kjent at det høye saltinntaket bidrar til å øke blodtrykket. Siden et høyt blodtrykk kan føre til en rekke livstruende sykdommer er det derfor viktig å ...

Denne masteroppgaven tar for seg fiskevernsonen rundt Svalbard og drøfter sonens status og framtidsutsikter. I lys av regimeteori blir det først gjort rede for hva slags regime som gjelder i fiskevernsonen. Fiskevernsonen blir her sett i forhold til de to tilknyttede regimene, som er svalbardregimet og havrettsregimet. Svalbardregimet er basert på Svalbardtraktaten, mens forskriftene om fiskevernsonen ...

The aim of this research was to prove a mandatory square mesh panel in the Basque trawling fleet operating in the ICES subzones VIIIabd. Selectivity parameters were calculated for the dual selection system (70 mm codend + 100 mm square mesh panel in extension piece) and for commercial codends (70 mm codend), with the aim to compare them and determine the effect of the square mesh panel in the overall ...

This paper reviews the bioeconomic literature on habitat-fisheries connections. Many such connections have been explored in the bioeconomic literature; however, missing from the literature is an analysis merging the potential influences of habitat on both fish stocks and fisheries into one general, overarching theoretical model. We attempt to clarify the nature of linkages between the function of ...

Polar cod (Boreogadus saida) is considered to be a key species in the Arctic marine ecosystems. Yet detailed or even basic knowledge regarding its biology and adaptations, especially during the polar night, are in many cases poor. No field data is presently available on the gonad development of polar cod, its reproductive biology and associated bioenergetics. Accordingly, polar cod was sampled at ...

Greenland halibut (Reinhardtius hippoglossoides, Walbaum) is a commercially important fish species in the Barents Sea. This fishery has been strongly regulated, including a fishing ban from 1992 to 2009. Studies of fish reproduction are needed to extend the knowledge about this species in order to improve management and to avoid another decay of the stock. This Master Thesis describes the relationships ...

In some bargaining situations, agreement has implications for agents beyond the parties involved, and if so, delays in reaching an agreement or failing to reach an agreement, when this would be profitable, may imply significant welfare losses. The question raised in this paper is whether the intervention of a government, who has a positive valuation of agreement and therefore offers a subsidy, will ...
