Questions Chefs Need to Ask When Purchasing Seafood
In the past decade or two, chefs across America have come
to understand the peril that many small-scale farmers are in and the
fragility of our heirloom and specialty food supplies. Many of us have
come to demand and expect regional, seasonal and organic or natural
produce, fruit and even meat and poultry. We have come to espouse the
flavors, textures and nuances of these wonderful products, naming them on
our menus, supporting and promoting the farmers and producers, and
educating our staff, peers and guests as to their importance.
I believe that the next phase of this trend is toward fish and shellfish.
In the past five years we have been hearing about depleted wild fish
stocks. We have often been told about the inherent challenges of fish
farming and in the past few years have seen numerous fish species added to
the endangered species list. In the past year numerous organizations have
produced booklets and guides to help us understand these issues and make
strides towards more sustainable seafood purchasing.
The following questions are ones that you might ask yourself when
purchasing seafood. These questions are meant to be a road map and a
guide, not a set of rules, for as chefs we need to balance a sustainable
restaurant and bottom line with our beliefs in a sustainable environment
and resource.
If the fish/shellfish is wild caught, you should ask:
-
Where was it captured?
Are the fisheries there well managed or are the stocks of the fish
depleted. The Audubon Seafood Lovers Almanac and the Chefs
Collaborative Seafood Solutions, both have this type of information.
Many fish, such as cod, Pollock, flounders, halibut, sole and plaice,
are relatively abundant in the pacific, but depleted in the Atlantic.
a. Protective management is needed to ensure the survival of
slow-growing fish that breed late in life such as: Sharks, Skates,
Rockfish, Patagonian Toothfish (Chilean Seabass) and Orange Roughy. b.
Highly overfished species, include: Groupers, Swordfish, Black Sea
Bass, Rockfish and most Snappers. c. Abundant or well managed species
include: Striped Bass, some Crabs, Alaskan Salmon, Oysters, Herrings,
Sardines, Anchovies, Mackerel, Mahimahi, Mussels, Alaskan Halibut, and
Pacific Albacore.
-
How was it caught?
Did its capture result in large amounts of accidental bycatch?
Non-selective fishing methods such as trawl nets, purse-seine nets and
longlines (dozens of miles with hundreds of hooks) can capture and
kill non-targeted species. Additionally, gill nets, purse seines and
bottom trawling can all result in high bycatch. Most bycatch consists
of dead fish and animals (including birds and turtles) thrown back
into the sea. a. Species with High Bycatch include: trawled shrimp,
Patagonian Toothfish, Orange Roughy, Oreo Dory, dredged Clams, and
Scallops. b. Low Bycatch Species include: Lobsters, rod and reel
caught Yellowfin Tuna, pole-caught Skipjack Tuna, Trolled Albacore
Tuna, non-dredged Clams, Mussels, Oysters and certified 밫urtle-Safe?Shrimp.
-
Was it captured in a way that damages ocean
eco-systems?
Hydraulic dredges can seriously degrade ocean floor habitats, as can
bottom-scraping trawl gear. a. Fish captured utilizing technologies
that may damage ocean eco-systems include: dredged Clams, Oysters,
Scallops, and Mussels as well as bottom-scraping trawled Shrimp,
Flounder and Monkfish.
If the fish/shellfish was farmed you should ask: 1. Was it raised in a
netpen or other potentially polluting system? These types of systems may
discharge large amounts of untreated wastewater that often pollutes the
waterways. a. Fish farmed in netpens or cages and open systems include:
most Salmon, Trout and Shrimp. b. Fish farmed in a less polluting manner
include: Catfish, Oysters, Clams, Scallops, and Mussels.
Some of the more Abundant, Well Managed or Sustainably Raised Species
include:
Hook and Line caught Atlantic Cod Striped Bass Catfish Alaskan Salmon
Mahimahi Atlantic Northern Pink shrimp Farmed Clams, Mussels, Oysters and
Scallops Alaskan Halibut Farmed Crawfish Pacific Cod Line caught Albacore
Alaskan Black Cod Blue Crab, Stone Crab and Dungeness Crab Closed system
Farmed Trout and Tilapia Herring, Anchovies and Sardines Pacific Hake
Mackeral
In closing I would like to stress that all of us need to educate ourselves
as to the intricacies of the seafood issues. We need to question our
seafood supplies, talk to our seafood suppliers, educate our customers and
most of all to understand that fish and shellfish are a renewable
resource, but only if we respect and cherish it.
