Guide To Eating Fish Responsibly

Why we need a sustainable fish guide to navigate our seafood purcahses

Many of us like clear cut answers. But when it comes to eating fish sustainably, it is a complex matter that deserves contemplation. Eating regenerative foods will benefit your health and the planet's health. But it does require a bit of intentional learning.

Fact: Wild fish populations are being depleted throughout the world’s oceans.

Fact: Wild fish are less prone to disease, free to roam, and in their healthiest most natural habitat.

Fact: Farmed fish are more prone to disease, often necessitating antibiotics and pesticides.

Fact: The antibiotics, fertilizers, pesticides, and other pollutants involved with concentrated farmed fish populations may end up contaminating our oceans and waterways.

Fact: Innovations in aquaculture can minimize contamination and pollution, and protect wild populations of marine life.

One can see why it isn’t always easy to determine if you should be consuming farmed or wild fish. True regenerative foods will revitalize both your body and the planet, so proper sourcing is a must.

Either way, diversifying one's consumption of fish will put less pressure on fewer species. Additionally, eating domestic, wild fish caught in season from small local fishermen will mean that you are sourcing from fisheries that are under strict and responsible management. Eating fish seasonally allows species’ to reproduce and naturally maintain a healthy population.


So what does a responsible consumer need to know?

                                    Other commonly eaten fish that are environmentally friendly options:

                                    Fish Icon 293733 Any fish that is farmed in indoor recirculating tanks that treat wastewater

                                    Fish Icon 293733 Sole from the west coast

                                    Fish Icon 293733 Arctic Char from Canada’s Cambridge Bay, or farmed in raceways from U.S, Canada, or Iceland

                                    Fish Icon 293733 Sanddabs from the west coast

                                      Fishing Techniques

                                      Gillnets & Seines:

                                      Fish Icon 3062620 Both of these methods involve using large nets to capture a mass of fish at one time, intended for schools of fish.

                                      Fish Icon 3062620 Cons: Catching so many fish at one time often leads to overfishing. Gillnets have a very high chance for bycatch - making it not environmentally sound

                                        Bottom Trawling & Dredges:

                                        Photo: Fix.com "The Three Biggest Threats To Global Fisheries"

                                        Fish Icon 3062620 Both methods involve dragging equipment along the ocean floor

                                        Fish Icon 3062620 Cons: damages the ocean bed, high chance for by catch, damages coral reef systems and leads to overfishing 

                                        Fish Icon 3062620 If there is one thing you learn in this sustainable fish guide - let it be that you should AVOID supporting this type of fishing.


                                          Midwater Trawls:

                                          Fish Icon 3062620 Pros: no damage to ocean floor as compared to bottom trawls.

                                          Fish Icon 3062620 Cons: high chance for bycatch, leads to overfishing, can catch at-risk species, can harm sea birds

                                          Fish Icon 3062620 Avoid when possible


                                            Trolling Lines and Pole & Line:

                                            Photo: Monterey Bay Aquarium Seafood Watch

                                            Fish Icon 3062620 Both methods involve bait on hooks on fishing lines.

                                            Fish Icon 3062620 Pole-and-line is generally one hook per line, while trolling lines are lined with many hooks.

                                            Fish Icon 3062620 Pros: The lines get pulled relatively quick once there is a bite, and the unwanted bycatch can be released into the ocean with little harm. Overall, this method is much less invasive and damaging than trawling and dredges. Hand operated lines, especially, do not lead to overfishing.

                                              Longlines:

                                              Fish Icon 3062620 Baited hooks dote these lines that are often miles long - up to 62 miles!

                                              Fish Icon 3062620 Cons: The bait used can lure at risk animals like endangered sea turtles. Overall, not a very sustainable method for catching fish. Contributes to overfishing.

                                                Handlines & Jigs:

                                                Photo: Monterey Bay Aquarium Seafood Watch

                                                Fish Icon 3062620 An often environmentally sound way to catch prized species.

                                                Fish Icon 3062620 Fishermen from small boats lure fish with a baited hook and by moving the jig around.

                                                Fish Icon 3062620 PROS: Small chance for catching unwanted species. Little to no environmental disruption.

                                                  Farming Techniques (Aquaculture):

                                                  Fish Icon 3062620 Fish are more susceptible to disease.

                                                  Fish Icon 3062620 Antibiotics, pesticides, sewage, and other toxic ingredients pollute the ocean

Mangroves are a critical ecosystem that many species depend on for food and habitat.

                                                        Fish Icon 3062620 Advances in shrimp farming and pond aquaculture have been put into effect in some instances. More advanced systems include above ground, closed loop systems that do not contribute to contaminating our waterways. Water is treated and used for multiple cycles.

                                                          The future of fish consumption is rooted in aquaculture. The demand for fish and shellfish simply cannot be met in a sustainable manner with only wild caught populations. Innovative technologies and sustainable systems will create aquaculture methods with minimal ecological footprint. There is already so much ingenuity within the field of sustainable aquaculture, with methods ranging from “marine permaculture” to systems in which fish waste is turned into a usable energy source. 

                                                          Conclusion:

                                                          While we'd all love a clear cut, black and white answer to conclude our sustainable fish guide, it is a grey area with many nuances. What it comes down to is this - there are sustainable ways to catch wild fish or to farm fish, and there are harmful ways to do either as well. Make sure to be aware of what fish species you consume, and how it was caught or farmed. By rotating between a wider range of species, and by eating seasonally, you can have a smaller ecological footprint. 

                                                           Do what you can to support ocean conservation:
