Some scientists predict a shortage of fish by 2050 . Overall, One in three fish species is threatened with extinction. Half of them are just renewing themselves. 7% of marine species have disappeared since 1950. 29% of the 600 species caught in the world are in the process of extinction: their level has dropped to 10% of that of 1950.

So how to behave? Stop eating fish is an option, but it is not ideal from a nutritional point of view. Buying less , and especially making the right choice is, at a minimum, highly recommended.

There are about 25,000 species of fish , but consumption is concentrated on about twenty species. Many species, less threatened, less known, are neglected. For the Seafood Retailers Australia this is important now.

What species of fish to buy?

We will review the different species of fish: those that we can buy without fear, those to avoid, and those to consume sparingly, or even to completely abandon.

Fish Buying Guide

There are general criteria to know to know how to buy a fish or conversely, why avoid it. There is no absolute assessment, and therefore unanimous agreement, to decide whether a particular species of fish is good for fishing and for buying or not buying by the consumer. However, we can focus on different criteria.

Is the choice of this fish good for the environment?

Is the fish species endangered? Is its stock sufficient to ensure the renewal of the species?
Does my fish respect the legal size of fishing? We must avoid fishing for fish that are not yet adults so that they can reproduce.

What fishing method was used? Dredge fishing is practiced to pick up some small shells such as clams. But this practice, which causes a lot of damage, is prohibited in Europe's sensitive ecosystems, especially in the Wadden Sea in the Netherlands. Unable to fish in Europe, some fishermen practice it in Mauritanian waters that are not subject to European jurisdiction, thus harming not only the environment, but also local fishermen. To avoid encouraging drag fishing, only buy clams from a local fishery. For the Seafood Retailers Australia this is the best deal now.

It is better to choose fish from farms that respect the environment ( MSC , organic)

Is it a farmed fish? If so, are the aquaculture operating conditions correct? You have to know that for some species, aquaculture is worse than wild fishing. Yet it accounts for about 50% of the world's "production" of fish.

Is this fish good for my health?

Is fish loaded with metals, such as mercury that affects brain function and development, in industrial chemicals?

Indeed, fish is the main source of mercury to which we are exposed. An Australian-American team has conducted numerous surveys, some up to 1,000 meters deep, in the North Pacific Ocean. She found that the amount of mercury in the waters of this ocean has risen by 30% in twenty years.
These toxins originate on continents and have been transmitted by small plants and small animals at the bottom of the ocean food chain.

These are eaten by larger animals that concentrate in their flesh these toxic in increasing quantity, without eliminating them. Some predators such as sharks, swordfish or seafood are particularly vulnerable to contaminants. You have to be careful when choosing them.
