Brill Fish

Fisheries and Uses

Due to its importance to recreational and commercial fisheries, Brill has high catches reported from many countries in the North East Atlantic, such as the Netherlands, United Kingdom, Ireland and Norway and from the Baltic Sea.

It is also an important species for aquaculture and is often farmed. Public aquaria are known to have Brill in their exhibits, and due to its abundance, it is considered a suitable mature fish for aquaria.

It is mainly fished using trawls, traps, and gillnets, with species-specific gear readily available, and it is marketed fresh or smoked, its flavour appreciated by many.

Furthermore, the wild-caught Brill often leads to its protection through certain conservancy and sustainability measures.

Management and Conservation

Given its importance to commercial and recreational fisheries, it is imperative to manage the population sustainably. Fishing methods are closely monitored, especially trawling procedures which can cause damage to their habitat, and quotas should be set to ensure their population remain healthy.

Research is ongoing to determine the optimal management practices and the most effective yields for the population in the English channel.

Restrictive regulations have been put in place to protect and manage Brill populations, such as the EU’s Water Framework Directive and the EU’s Marine Strategy Framework Directive. Additionally, the International Council for Exploration of the Sea (ICES) has adopted a Standardised Monitoring Protocol to ensure the sustainable management of the Brill population and other flat fish.

According to the International Union for Conservation of Nature (IUCN), this species is least concerning mainly because of its high stock levels, so you can feel good about purchasing it.

Conservation Status

The population of Brill has decreased in some parts of its range due to overfishing. Therefore, it is essential to fish responsibly, following the recommended quotas set by regional fisheries. The Marine Stewardship Council recommends buying Brill from certified fishers to ensure sustainable fishing practices are employed.

Changing environmental conditions, such as water temperature, salinity, and levels of pollutants can significantly affect Brill’s behaviour, reproduction, and feeding habits.

As a result, much conservation and management effort have been put into protecting this species, as it is a commercially important species in some areas and is at risk from overfishing and other anthropogenic activities.

Sustainable Fishing Practices

Various conservation efforts are being made to try and increase the population of Brill, including restocking efforts, gear switch programmes, and public awareness campaigns.

Artisanal fishing, which employs more traditional, artisanal gear such as gillnets, is also crucial in reducing pressure on Brill populations, as it is less damaging to the environment than trawl fishing.

The replenishment of juvenile Brill stocks through aquaculture is also necessary. Some countries have adopted best-practice management techniques that enable the sustainable fishing of Brill, reducing mortality rates by limiting bycatch and juvenile mortality while also ensuring a healthy, sustainable supply.

Life Cycle of Brill

The life cycle of Brill starts with the female laying her eggs in late spring to early summer. The eggs, which measure 0.8 mm in diameter, are spread over several locations to increase their survival rate. After 4-8 days of incubation, the eggs hatch to form semi-transparent larval Brills, which are highly vulnerable to predation.

As the larvae grow, they become more streamlined and eventually assume the permanent lateral line adult form. During this time, Brills migrate to deeper parts of the water column to forage for small animals such as worms, crustaceans, molluscs, and larvae of other species. After 1-2 years of growth, Brill reaches maturity, becoming capable of reproducing.

Adult Brills typically return to their spawning grounds at the end of their life cycle. Spawning’s main season naturally occurs in the Atlantic from April to June and in the Mediterranean from November to February in ocean depths ranging from 30 to 200 metres. Juveniles live in shallow coastal waters and gradually migrate offshore as they mature.

The maximum recorded lifespan is 18-22 years.

Brill’s Diet

Brill is an opportunistic and omnivore predator that eats plants and animals. Its diet consists of small crustaceans such as prawns, shrimp, crabs, plankton, benthic invertebrates, fish eggs, worms, small fish, jellyfish, molluscs, and algae.

Adult Brill feed primarily on sand eels and sprat, while juvenile fish feed on plankton, prawn larvae, crustaceans and small fish.

High Availability and Culinary Significance

Brill is an economically important fish species due to its availability, abundance, and culinary value. This attribute of brill has given rise to a range of international regulations and guidelines, spearheaded by the Food and Agriculture Organisation of the United Nations (FAO), to ensure that the fish are sustainably sourced worldwide. In addition, the Dutch region has a long tradition of consuming this fish species as part of its culinary culture.

Brill is a popular Italian delicacy known for its mild flavour and soft texture. It is an ideal choice for chefs looking to add a Mediterranean flair to their dishes and can often be found as Brill fillets, or the ‘Queen of Fish’ or the ‘Queen of the Mediterranean’. Brill is perfect for various dishes and is popular among seafood connoisseurs.

Recent Popularity

In recent years, brill has enjoyed increased popularity due to its sustainability and availability in markets and restaurants. It is a popular seafood option due to its flaky texture, mild taste and sustainability, making it a valuable food source for people in Europe and worldwide.

It is also a good source of omega-3 fatty acids, vital for brain health, heart health, and immune system functioning. Several B vitamins, including B12, B6, and B2, as well as minerals such as folate, niacin, and riboflavin, are also present in high concentrations.

One fillet of the Atlantic brill provides 163 calories, with 2.6 g fat, 0.7 g saturated fat, 28 g protein, 10 g carbohydrate, and 0.7 g sugars.

Health Benefits

Consuming Brill has several health benefits. The omega-3 fatty acids it provides help to reduce inflammation in the body. At the same time, its high levels of Vitamins B12 and B6 and minerals such as selenium are required for proper neurological and immune system functions. Additionally, Brill is low in mercury, making it a safer seafood option.

Taste and Texture of Brill Fillets

The taste of Brill is subtle and sweet, with a light flavour and delicate texture. It is sometimes compared to Cod due to its mild flavour. Consisting of high-fat content, Brill has a slightly fatty taste when cooked. Depending on how it is cooked, it may take on a slightly nutty flavour with hints of butter.

The flesh of the Brill from the freezer is light and firm and can be cooked in various ways, including baking, poaching, grilling, and frying. Brill is slightly less resilient than Cod or Haddock and has more of a flaky texture, so it is best cooked quickly over medium-high heat.

Eating Brill

The versatile Brill can be used in many dishes, such as Brill en Croûte, Brill Louisiana-style, or baked Brill with garlic butter. Fillets of aquatic delights make for excellent replacements in fish and chip shops, where they are increasingly popular. As Brill has a mild taste, the flesh absorbs other flavours easily, so it can be cooked with herbs and spices to enhance the flavour.

In addition to entrees, Brill can be served as an accompaniment to salads, stews, soups, fish pies, and crumbed dishes. It can even be smoked or cured to make a delicious delicacy and is often found in sushi and fish tacos. As it is very high in omega-3 fatty acids, Brill is an excellent choice for those watching their nutrition.

Cooking Brill

Brill can be prepared in various ways, depending on the prescribed recipe. Standard preparation methods include grilling, baking, poaching, steaming and pan-frying, and each has its unique technique and flavour.

When grilling, it should be baked in a sheet of aluminium foil for about 10 minutes to ensure complete cooking. For poaching, use a flavorful liquid, such as white wine or fish stock, for a richer flavour.

Brill can be wrapped in parchment paper with selected aromatics such as garlic, herbs, and lemon for baking. To steam it, place it in a steamer and heat for about five minutes or until opaque.
