Shrimp

Shrimp is a type of crustaceans with elonged bodies and a primarily swimming mode of locomotion. Under the broader definition, shrimp may be synonymous with prawn. Covering the stalk-eyed swimming crustaceans with long muscular tails long whiskers and slender legs. Any small crustaceans that resemble a shrimp are called one. The habitat of the shrimp covers all waters, near the shore, rivers, lakes and in the deep sea. There are several types of shrimp on the dutch market. Wild shrimps from colder waters like the brown shrimp and the northern prawn are in general a bit smaller. Big shrimps or prawns also referred to as ‘gamba’, are most often imported from tropical areas, where they are farmed.

The tiger shrimp is native to the warm coastal waters of the Indian Ocean and western Pacific Ocean. In the 1980s, the species was accidentally introduced to the US, along the coast of South Carolina. Nowadays, this species also occurs along the southeastern coast of the US and in the Gulf of Mexico. Warm water shrimp usually grow significantly larger than cold water shrimp. The commercially popular large, warm-water shrimps are called ‘gambas’ or ‘tropical shrimp’. Gamba’s of which the head is removed are traded as scampi. In English, king prawns are called ‘prawns’. Small shrimp, such as the Nordic and Dutch (or gray) shrimp, are called ‘shrimps’.

The tiger shrimp is the largest among the Penaeus species. It can grow up to 334 mm long and weigh 250 grams. Tiger prawns are caught with a bottom trawl, but are also widely farmed by smallscale farmers in Southeast Asia and Central and South America.

Explanation assessment

There is a huge demand for tropical shrimp, unfortunately the aquaculture has also several problems. ASC-shrimp are available since 2015. The certification program of ASCASC:
Aquaculture Stewardship Council, a worldwide eco-label for responsible cultivated fish.
rewards aquaculture activities that target protection of the environment and social responsibility.

The creation of the ASC standard is unique for the dialogue between the many stakeholders. This has led to a standard that is strict and realistic and they handle the most important negative effects of shrimp aquaculture. For example, that the waste products don’t burden the environment too much, the amount of escapes of shrimp, the abuse of antibiotics and whether the company is run in a socially responsible way.

Explanation assessment

Tropical shrimp is very much loved by consumers worldwide. There can unfortunately be a lot of problems with shrimp aquaculture. In the past, a lot of mangrove forests were cut to make place for aquaculture ponds, nowadays the ponds are mainly placed in other coastal areas, but these are also areas with a high ecological value. The chance of diseases by shrimp is high, and to combat that high quantities of medicines, antibiotics and chemicals are used in the aquaculture. The law and regulation in countries where shrimp is farmed is often not good enough to minimalise the harmful effects of the aquaculture.

Final assessment
Explanation assessment

Most shrimp stocks in this region are intensively fished or overfished, which pressures the stocks. Catch data are unreliable and it is unclear whether the existing management measures are being followed. Illegal fishery plays a big part in this.

Trawling fisheries have generally much bycatch, including young, undersized fish. 20-80% of the catch is bycatch, of which much is discarded. At some places everything is landed. Furthermore, there is incidental bycatch of protected species, like sea turtles, rays and sharks. Fishing with trawls touches the bottom and there is a direct disruption of the bottom life. Intensive fishing with bottom trawls leads on the long-term to a change in species composition in the sea. This is especially the case for vulnerable habitats like coral reefs and sea grass fields that occur in this region.

 

ASC label

Fish with the ASC label is farmed in a sustainable manner.

MSC label

Fish with the MSC label is caught sustainably.

Good fish

This fish is not being overfished or is being responsibly farmed, with minimal impact on the environment.

Second choice

This fish is a second choice. There are still some improvements to be made in this fishery or fish farm.

Avoid

Do not buy this fish. It's being overfished or the way it's farmed or caught has a negative impact on the environment.

By-catch

This fish is unwillingly caught while fishing for a different species. They are underused and should be eaten more.

GlobalG.A.P.

GlobalG.A.P. certified farms are doing a step in the right direction in terms of sustainability. A few species with this label are getting a better score on the VISwijzer.

Organic

Organic standards are the strictest when it comes to fish feed. They also require certain measures for animal well-being.
