3. What are
Ymax = MSY
some
examples of -Ymax occurs when the population size is at about hald the carrying
Overexplota- capacity of when biomass is half of its max value
tions
-MSY = rK/4
- Commercia
l harvesting k= Carrying Capacity
r = intrinsic rate of 'stock' growth
4. Overexplota- if r has a value of 2 the population is capable of double every year till K
tions reached
- Commercial
harvesting 80% of the worlds fish stock classified as over
Problems fished why ?
with MSY
-diflcult to coordinate catches across internatioinal boundaries
5. Commercial -illegal catch not accounted for
har- vesting - -large portions of juvenile populations can be damaged during
what is
Bycatch ? harvesting operations
Marine birds that are trapped in nets, or other fish species that are not
desirable, killed for no reason
6. What are

- International
wildlife trade
7. Define - Inter-
national defined as the sale or exchange of any wild animal or plant (including
wildlife trade trees), one might also finger both a rising population and sharp increase
in the globalization of commerce over the same period.
8. what are
some solutions -Conservation projects increasingly linking conservation of biodiversity
for Overexploita-
tion ? and local economic development
-acknowledging sustainable harvesting of a natural resource with special
certifi- cates
-parks, reserves and sanctuaries

species from convention on international trade in endangered species of wild
dis- persing
globally ? fauna and flora)
