W2 ENR 3300 - Int For Wish Wildl
Fishery12
•
An activity that leads to the harvest of fish.12
•
Can involve the capture of wild fish or the raising of fish through aquaculture.12
•
Includes not just fin fish, but also non-fish organisms such as crabs, lobsters, and oysters.23
Aquaculture14
•
The breeding and rearing of plants and animals in all types of aquatic ecosystems.4
•
Can occur in various settings, such as tanks, ponds, or pens in the natural environment.45
Maximum Sustainable Yield (MSY)678
•
The largest average yield or catch that can continuously be taken from a species' stock under existing environmental conditions.78
•
The goal of fishing at this level was embraced by the world community and incorporated into international agreements.9
•
Represents a theoretical maximum; fishing at this level is risky.1011
Biomass (BMSY)8
•
The long-term average biomass level (the weight of all the fish in a specific stock) needed to maintain MSY.8
Fishing Mortality Rate (FMSY)812
•
The rate at which fish are removed from a stock through fishing that results in BMSY for a fish stock.8
•
The fishing mortality rate which generates MSY should be regarded as a minimum standard for limit reference points.13
Precautionary Principle141516
•
A management approach that emphasizes caution when information is uncertain, unreliable, or inadequate.141516
•
Requires management to be more cautious when information is uncertain, unreliable, or inadequate.15
•
Entails developing management policies that account for inherent risks and uncertainties.16
Target Reference Point1617
•
A point intended to meet management objectives.1617
•
Management strategies should be designed so that the target reference point is not exceeded on average.18
Limit Reference Point1617
•
A point intended to constrain catches within safe biological limits.1617
•
FMSY is considered the minimum standard for limit reference points.17
•
Management strategies should ensure that the risk of exceeding this limit is very low.18
Stock Assessment1920
•
A process that uses data to estimate the abundance, biology, and catch of a fish stock.19202122
•
Considered the backbone of fisheries management.1923
•
Used to determine a sustainable level of fishing.24
Abundance Data23
•
Data collected to estimate the amount of fish in a stock via numbers or biomass.2325
Biological Data25
•
Data collected to determine the age, size, growth rates, and mortality of fish.25
Catch Data26
•
Data collected to record the amount of fish harvested from a fishery.26
Ecosystem Based Management27
•
An approach to fisheries management where consideration is given to the entire ecosystem instead of only the target species.2728
Magnuson-Stevens Act293031
•
U.S. legislation that governs fisheries management in the U.S.2930
•
Aims to prevent overfishing, rebuild overfished stocks, and ensure a safe and sustainable supply of seafood.31
•
Incorporates maximum sustainable yield as an approach for determining catch limits.30
IUU Fishing9
•
Illegal, unregulated, and unreported fishing.9
