Effect of production quotas on economic and environmental values of growth rate and feed efficiency in sea cage fish farming
In sea cage fish farming, production quotas aim to constrain the impact of fish farming on the surrounding ecosystem. It is unknown how these quotas affect economic profitability and environmental impact of genetic improvement. We combined bioeconomic modelling with life cycle assessment (LCA) to calculate the economic (EV) and environmental (ENV) values of thermal growth coefficient (TGC) and ...
متن کاملSea-cage Fish Farming and Declines of Wild Fish
It has often been observed that after sea-cage fish farming begins in a coastal area, nearby wild fish populations steadily or precipitously decline due to elevated levels of pathogens and parasites. Such declines can be understood using three methods, in increasing level of mathematical difficulty: (1) an intuitive approach based on the inverse-square law of radiation applied to parasite trans...
متن کاملCharacterization of manures from fish cage farming in Chile.
This study aims to characterize salmonid manures and to determine their potential use in agricultural soils. Sampling was carried out below salmon and trout cages in farms located in lakes and in the sea in the South of Chile during 2002-2003. Manure was analyzed for macronutrients, micronutrients and heavy metals. Results showed a high variability between samples and differences between sea an...
متن کاملPerformance and Economic Feasibility of Using Soybean Oil, Palm Oil and Fish Oil in Broiler Diet
Six hundred day old unsexed broiler chicks were used in a 35-day trial to compare the effects of soybean oil, palm oil and fish oil supplementation on the performance of broilers in terms of feed intake, weight gain and feed conversion. The chicks were randomly distributed following a completely randomized design in four groups having three replications per treatment. Each treatment had 150 bir...
متن کاملProductivity growth, technical change and efficiency change of the Malaysian cage fish farming: an application of Malmquist Productivity Index approach
The demand for animal protein especially fish is expanding due to the population growth, increased incomes and changes in eating habits and life styles. The capture fisheries in Malaysia which supply over 70 % of the fish used for food are over-exploited, and the yield has become stagnant over the last decades and in some cases it has even declined. In addition, the balance of trade for the pas...
