A few months ago I discussed sustainable seafood options in Australia in Unsustainable Seafood Choices In Australia + Better Choices. Prawn lovers may have been upset to find that prawns were an unsustainable seafood choice due to their destructive fishing methods. This is unfortunate news for a prawn-loving nation and for many Dietitians who often recommend them as a healthier alternative to high-fat meats.
Spot Prawns A Sustainable Canadian Seafood
Spot Prawns Are A Sustainable Choice
Imagine my surprise when coming over to Canada and seeing BC’s very own Spot Prawns on Environmental Scientist and Activist David Suzuki’s Top 10 Sustainable Seafood Picks. After some more investigating I found that SeaChoice, Canada, gave them a green light or “Best Choice” in terms of sustainability.
What Is The Sustainability Criteria Used?
This assessment is based on the five sustainability criteria used for fisheries assessments:
- Inherent vulnerability to fishing pressure;
- Status of wild stocks;
- Nature and extent of discarded bycatch;
- Effect of fishing practices on habitats and ecosystems;
- Effectiveness of the management regime.
Why Are Spot Prawns A Sustainable Choice?
What makes BC Spot Prawns so different from other prawn species is the method of fishing used. Instead of big trawlers digging up the ocean floor, Spot Prawns are caught using traps. Traps reduce bycatch and the prawns are managed on a female: male ratio. Fisheries are only opened for a few months of the year starting in early May and only 252 licenses were issued this year.
Are All Spot Prawns Sustainable?
No, this refers only to Spot Prawns caught on the Canadian Pacific. Other Spot Prawns, including those caught off America’s Washington and California coast, have been given the amber light “Some Concerns” due to a medium level of bycatch and link to moderate habitat damage.
How To Enjoy Prawns Sustainably
Prawns Are Imported From Asia
In North America, prawns are the most popular seafood of choice. From pasta dishes to sandwiches to curries, prawns taste great so many ways. How and why are we eating so many prawns? More and more they are coming from tropical shrimp farms in Southeast Asia and Latin America.
The Unsustainability of Important Prawns
Unfortunately, the effects are high levels of disease and pollution and devastation of 40% of the world’s mangroves. In case your wondering, mangroves play an important role in reducing CO2 emissions and store 5 times more carbon than even tropical rainforests. Not to mention their role in the filtering of waterways to protect coral reefs and also being the habitat of many animal species. The Mangrove Action Project has a lot more excellent information on this topic here.
How Do We Know What Prawns Are Sustainable?
Spot Prawns Vs Imported Prawns
Spot Prawns have a distinctive reddish-brown shell and their abdomen has white spots. They are also the largest shrimp species found on Canada’s west coast. You can find them at local Ocean Wise markets and restaurants. Click here for a list of restaurants and markets where you can find these seasonal prawns. Check out SeaChoice here for more information on sustainable prawns.
Sustainable Prawns In Australia
In Australia refer to the Australian Marine Conservation Society. Currently they only sustainable prawn option is haul caught School and Bay (Greentail) Prawns in NSW.
A Dietitians Last Words On Prawns
Health Benefits of Prawns
Prawns are an excellent source of protein, a good source of omega 3 fatty acids and a great way to get iron, zinc and vitamin E. They are also low in saturated fat and are a great source of iodine.
Prawns and Dietary Cholesterol
If you can get your hands on some BC Spot Prawns which are available frozen year-round, then make sure you don’t go overboard. Prawns are high in natural cholesterol which may affect your cholesterol levels. Currently, recommendations are 300 milligrams of dietary cholesterol per day or 200mg if you have a history of heart disease or diabetes. A 100 gram serving of prawns may contain anywhere between 120-250 milligrams of dietary cholesterol depending on the species. Enjoy responsibly and sustainably.
