ustainable
fisheries are sustainable because they are very focused
fisheries, catching the target species and little
else. Fishing method and area of capture are two of
the most important factors to be considered when judging
a fisheries sustainability and management. Different
fishing methods are more acceptable at different times
and in different areas for each species. An indiscriminate
longline fishery during the 1970's was responsible
for the crash of Atlantic swordfish populations while
today halibut longlining in Alaska is a well managed
sustainable fishery which successfully addresses all
management issues.
ICON (?)This icon indicates that a fishery
has some positive aspects such as method and area
of capture or a new management plan yet may have negative
factors such as a history of overfishing or the gear
selection is not ideal. Somewhat like the difference
between Certified Organic produce and Transitional
produce. Make your own decision.
Albacore
Albacore jig boats fish by dragging jigs (lures) behind
the boat on individual lines. The north pacific albacore
fishery is eco friendly in that there is very little
by-catch and no impact on fishery habitat. Unlike
some other tuna species, albacore do not usually swim
with dolphins -- and for this reason there is not
a dolphin-associated albacore fishery anywhere in
the world. This is true of both fresh and canned albacore.
Fishery researchers generally agree that the North
Pacific albacore population is a healthy stock at
the current time.
Anchovies
Huge, dense schools of anchovy are easily captured
in seine nets with very little bycatch. The various
anchovy populations in U.S. waters are currently abundant
and appear to be doing well.
Catfish
Catfish are aquacultured in closed system freshwater
ponds, having no impact on wild fish or the environment.
Crab, Dungeness
The Dungeness crab fishery is a pot fishery with restrictions
on size, gender, males only, and season. While considered
a well managed fishery natural fluctuations in stock
size do occur. There is little habitat impact and
only minor issues of by-catch.
Clams, manilla (?)
Commercial supply is 100% maricultured, small growers
such as in Tomales Bay use Rack and Bag method which
suspends clams off the bottom, a faultless industry.
Larger farms plant clams in gravel beach areas then
rake them up when mature, disturbing the inherent
structure of the community.
Halibut - Alaska
Prior to 1960 the Pacific halibut was fished to the
verge of extinction, an intensely regulated program
was very successful in rebuilding the halibut fishery
back to record levels. The present well managed, long
line fishery
produces top quality halibut with accountability for
by-catch and little habitat interference.
Halibut - California(?)
Although not a true halibut but rather a giant flounder
there is a successful Hook and Line fishery centered
in the Bay area producing top quality fish. Lots of
large fish this year seems to indicate good recruitment
for upcoming years. Regulations address minimum size
and area open to fishing. 2001 regulations have phased
out gillnetting but a trawl industry does exist.
Herring
Atlantic and Pacific herring are abundant. Very little
by-catch is involved in seine herring fisheries. Although
human consumption of these fish has very little impact
on populations, commercial fishing fleets that "fish
down the food chain", targeting small-pelagic
fish, for fertilizer, fish oil and animal feed are
a threat to this critical part of the marine foodweb.
Lobster
The lobster is perhaps one of the only species that's
been intensively fished for 150 years and is doing
better today than ever. The habitat friendly use of
lobster pots, size restriction and regulation against
possesing breeding females add up to a well-managed
fishery. The preponderance of small sized lobsters
make some scientists skeptical about the viability
of lobster stocks.
Mackerel
Dense schools of these small pelagic fish allows for
very specific targeting with seine nets. Very little
bycatch, no habitat impact. Same concern as Herring
"fishing down the foodchain".
Mahi - Mahi
Mahi-mahi, one of the most stunningly beautiful fish
in the ocean, inhabits all the tropical and subtropical
seas of the world. The Mahi-Mahi is a prolific breeder;
the female may spawn 3 to 4 times per year, and grows
quickly as its lifespan is a mere 4-5 years. Their
rapid growth and short life span allow them to sustain
heavy catch efforts without fear of over fishing.
Mahi-mahi is commercially harvested by hook-and-line.
Stock assessment is non-existant and unregulated.
Mussels
Probably 100% of the mussels sold on the West Coast
are the superior quality maricultured mussel. While
maricultured fish are detrimental to the environment
and wild stocks, maricultured shellfish don't have
any impact on habitat or by-catch and may even improve
water quality where grown. Shellfish farmed via off-bottom
methods, such as rack and bag or on lines, have the
least impact on seafloor habitat. Some wild East Coast
mussels may be dredged but they would be sold locally.
New Zealand Fisheries management
The New Zealand quota management system introduced
in 1986 has earned New Zealand the reputation as a
world leader in the search for sustainable fisheries
management. Each area within New Zealand's exclusive
economic zone, or 200 mile limit, is assigned a yearly
total allowable catch for each of the 46 species of
seafood commercially fished. The total allowable catch
is set conservatively, so that enough fish remain
to maintain breeding future populations. The total
allowable catch is then divided into a number of Individual
Transferable Quotas, which are effectively rights
to fish a defined portion of the allowable catch.
The quota management system implemented through the
use of individual transferable quotas in conjunction
with the use of marine reserves has created a sustainable
management program that really works. New Zealands
conservation program should be the model for fisheries
conservation throughout the world.
Oysters
All the oysters that are grown and sold on the West
Coast are maricultured. While maricultured fish are
detrimental to the environment and wild stocks, maricultured
shellfish don't have any impact on habitat or by-catch
and may even improve water quality where grown. Shellfish
farmed via off-bottom methods, such as rack and bag
or on lines, have the least impact on seafloor habitat.
Gulf and Atlantic seaboard oysters may be dredged
which adversely effects fishery habitat.
Prawn, Spot(?)
Spot prawns from a well managed pot fisheries in Alaska
are heavily regulated, less so in California. Trawl
fishery with all the problems of by-catch and habitat
destruction are the major fishery in California.
Rockfish(?)
Of the 52 species of rockfish found off the coast
of California some are threatened such as the Boccacio
and Canary rockfish, some, like the Chillipepper,
are in good shape. Hook and line fishermen are able
to target a particular species, have no impact on
essential fisheries habitat, are responsible for very
little by catch and are able to avoid juvenile fish
through gear regulation. Family subsistence fishermen
are committed to keeping local stocks healthy, as
they are unable to move on to a different area or
species after a fishery has been decimated by other
fishing methods.
Salmon
Fall run Sacramento River Chinook salmon is the perfect
example of a well-managed, sustainable fishery. These
are open-ocean troll caught fish caught on barb-less
hooks, so undersized salmon and by-catch can be released
unharmed. As well, there is no impact on essential
fisheries habitat.
San dabs
The Pacific SandDab is a wonderful little fish found
in great abundance off our California coast. One of
the most numerous fish along the west coast, the SandDab
in chameleon like fashion is able to change color
and pattern to match sand, gravel or shell rubble
bottom thus go unnoticed by prey. Highly targeted
Danish Seine netting accounts for very little by catch
and minimal habitat impact. Dense schools of San dabs
are easily targeted by the trawl fishery reducing
by-catch but having some impact on habitat.
Sardines
During the 1930's and 40's the Pacific sardine accounted
for one-fourth of all the fish landed in the United
States. Due to poor fishery management and global
weather conditions the sardine industry totally collapsed
in the early 1950's. Due to favorable ocean conditions
and strict management the sardine is in the midst
of an explosive recovery. Highly targeted Seine netting
accounts for very little by catch or habitat impact.
Scallops(?)
The Sustainable Fisheries Act of 1996 mandate to improve
regulation of scallop stocks, along with some gear
improvement has led to an extraordinary rebound in
scallop populations. Higher catch results than have
been seen in 40 years have been reported. Although
scallop trawl gear has recently been improved it is
still the weak link in this fishery from an environmental
point of view
.
Shrimp - Turtle free (?)
Shrimpers along the North Carolina and Georgia coast
have long been in the forefront of responsible fisheries
management. In the deep water off the South east Atlantic
coast there is little Turtle grass to attract juvenile
fish, just hard bottom. Therefore there is much less
by-catch and fisheries habitat impact than in the
Gulf of Mexico. Shrimp stocks in this area are closely
monitored by both state and federal authorities in
order to insure a well managed fishery, decisions
on when and where to shrimp are made on a seasonal
basis.
Skate (Raja Radiata & spp.) (?)
Over-fishing of the gadoids (cod, pollock, haddock,
and hake) and flat fish has led to a shift in the
makeup of the biomass on Georges Banks. Valuable ground-fish
populations have declined, while lower-value small
elasmobranchs (skates and dogfish) have increased
greatly relative to the total biomass.
Because skates are part of the New England ground-fish
management plan they are tallied into catch figures
thus impacting catch regulations. For this reason
fishermen will at times avoid catching skate so as
not to impact allowable catch of higher valued ground-fish
thus creating artificial shortages.
Skates seem to be very abundant but the usual problems
of habitat destruction and by-catch associated with
a trawl based fishery must be taken into account.
Smelt
Night smelt, also known as whitebait and Day smelt
or candle fish are named for the time when they come
to the beach to spawn. When these diminutive little
fish gather on pacific Northwest beaches to spawn
they are easily captured with hand-held dip nets.
These nets have no impact on essential fisheries habitat
or by-catch. Due to low consumer demand and a low
impact method of capture, both the day and night smelt
fisheries are underutilized at this time.
Petrale/ English(?)
Pacific Coast Petrale and English sole stocks are
abundant, all environmental groups classify West coast
flatfish as a "green selection". The commercial
fishery is almost exclusively by trawl with all the
problems of by-catch and habitat destruction.
Striped Bass
Years of controversial restrictions on Striped Bass
along the Atlantic seaboard have paid off. Fisheries
officials have declared that rockfish stocks are fully
recovered from their depleted levels of the late 1970s
and early 1980s. Quality Striped bass are caught by
Rod and Reel or in weirs (traps), a traditional American
Indian method of fishing whereby fish are entrapped
in a net or stake corral then harvested by hand-brailling
with scoop nets.
Squid
Over the past five years squid has soared past salmon,
swordfish and tuna to become the top seafood species
in California by volume and dollar value. New rules
are a rare example of government stepping in to regulate
a fishery before it crashes. The good news for many
in the fishing community is that after several years
of scientific study, the Department of Fish and Game
report found that squid populations are healthy despite
heavy fishing.
Highly targeted Lampara Seine netting accounts for
very little by catch and minimal habitat impact.
Swordfish(?)
The status of swordfish and other billfish is not
completely understood in the Pacific, but populations
are believed to be fished to full capacity. Average
size Pacific swordfish is 200 lbs while average size
Atlantic swordfish is 90 lbs, a good indication of
the relative health of the respective stocks. Pacific
fisheries management council is currently developing
a management plan to ensure sustainability. California
regulations allow only harpoon and gillnet fisheries
which have very little impact on juveniles and bycatch,
particularly when compared to Pacific longliners.
Tai Snapper
Tai Snapper of the family Sparidae or sea breams
are the most important part of the New Zealand inshore
fishery. They are caught commercially on longlines,
killed immediately, then cooled quickly in brine.
Over 30,000 tonnes of snapper are landed annually
in New Zealand and this is the most popular eating
fish both for local consumption and for export. For
a description of management see New Zealand fisheries
management above.
Trout
Trout are aquacultured in closed system freshwater
systems, having no impact on wild fish or the environment.
Tuna
Yellowfin Tuna's, both Pacific and Atlantic, are not
considered to be overfished but rather fished to maximum
sustainable yield. Fresh Yellowfin tuna are most often
fished by rod and reel or longline. Pacific Bluefin
are in much better shape than their Atlantic cousins.
The longline fishery does have all the issues of by-catch.
White Sea Bass
Perhaps the best news coming out of this fishery is
that the populations, at least off California, are
believed to be on the upswing. "They're definitely
coming back," says state fish and game biologist
Steve Crook, based in Long Beach. "We suspect
a tremendous natural recovery in the stocks."
2001 regulations have virtually ended all gillnet
fishing for White Seabass in California. The current
Rod and Reel fishery should help the continuing recovery
of stocks while providing top quality fish.
