U.S. mariculture production of bivalve molluscs-those cultivated in
the marine environment-has roughly doubled over the last 25 years.
Although mariculture operations may expand the production of
seafood without additional exploitation of wild populations, they
still depend upon and affect natural ecosystems and ecosystem
services. Every additional animal has an incremental effect arising
from food extraction and waste excretion. Increasing domestic
seafood production in the United States in an environmentally and
socially responsible way will likely require the use of policy
tools, such as best management practices (BMPs) and performance
standards.
BMPs represent one approach to protecting against undesirable
consequences of mariculture. An alternative approach to voluntary
or mandatory BMPs is the establishment of performance standards for
mariculture. Variability in environmental conditions makes it
difficult to develop BMPs that are sufficiently flexible and
adaptable to protect ecosystem integrity across a broad range of
locations and conditions. An alternative that measures performance
in sustaining key indicators of ecosystem state and function may be
more effective. Because BMPs address mariculture methods rather
than monitoring actual ecosystem responses, they do not guarantee
that detrimental ecosystem impacts will be controlled or that
unacceptable impact will be avoided.
Ecosystem Concepts for Sustainable Bivalve Mariculture finds that
while performance standards can be applied for some broad ecosystem
indicators, BMPs may be more appropriate for addressing parameters
that change from site to site, such as the species being cultured,
different culture methods, and various environmental conditions.
This book takes an in-depth look at the environmental, social, and
economic issues to present recommendations for sustainable bivalve
mariculture.
