sustainable yield — the yield (in weight or number) taken from a fish stock when it is in equilibrium with fishing of a given intensity, and (apart from effects of environmental variation) its biomass is not changing from one year to the next. Also called… … Dictionary of ichthyology
Sustainable yield in fisheries — The sustainable yield of natural capital is the ecological yield that can be extracted without reducing the base of capital itself, i.e. the surplus required to maintain ecosystem services at the same or increasing level over time. This yield… … Wikipedia
sustainable yield — Catch that can be removed over an indefinite period without causing the stock to be depleted. This could be either a constant yield from year to year, or a yield which is allowed to fluctuate in response to changes in abundance; see… … Fisheries — dictionary
sustainable yield — The number or weight of fish in a stock that can be taken by fishing without reducing the stock biomass from year to year, assuming that environmental conditions remain the same … Fisheries — dictionary
sustainable yield — The number or weight of fish in a stock that can be taken by fishing without reducing the stock biomass from year to year, assuming that environmental conditions remain the same … Fisheries — dictionary
Maximum sustainable yield — In population ecology and economics, maximum sustainable yield or MSY is, theoretically, the largest yield (or catch) that can be taken from a species stock over an indefinite period. Fundamental to the notion of sustainable harvest, the concept… … Wikipedia
Maximum sustainable yield in fisheries — In population ecology and economics, maximum sustainable yield or MSY is, theoretically, the largest yield/catch that can be taken from a species stock over an indefinite period. Under the assumption of logistic growth, the MSY will be exactly at … Wikipedia
Optimum sustainable yield in fisheries — In population ecology and economics, optimum sustainable yield is the level of effort (LOE) that maximizes the difference between total revenue and total cost. Or, where marginal revenue equals marginal cost. This level of effort maximizes the… … Wikipedia
Optimum sustainable yield — In population ecology and economics, optimum sustainable yield is the level of effort (LOE) that maximizes the difference between total revenue and total cost. Or, where marginal revenue equals marginal cost. This level of effort maximizes the… … Wikipedia
maximum sustainable yield — the average or maximum catch that can be removed under existing environmental conditions over an indefinite period without causing the stock to be depleted, assuming that removals and natural mortality are balanced by stable recruitment and… … Dictionary of ichthyology
