In this brief article, we will answer the questions, are hatchery trout safe to eat, what are they, how are they produced, and how to prepare them. We will also answer why you should consider eating them and if there are any risks associated with them. 

Are hatchery trouts safe to eat?

Hatchery/stocked trouts are safe to eat. They serve as an excellent dish that is rich in minerals, vitamins, and proteins.

They can be kept in small aquariums and are available in most fish restaurants and vendors. 

What are trouts?

Trouts are small types of fish of the family Salmonidae. They are closely related to salmon and char fish. 

There are three variations of the trout. They are rainbow trout, brown trout, and brook trout. Rainbow trout is the most common. 

They live in fresh waters and mostly live at sea for 3 years before returning to the rivers to spawn. They are a great source of food for bears, humans, and other animals. They also possess a set of teeth that acts as a distinction between them and salmon.

The trout feed on other small fish and small soft invertebrates such as mollusks. They are found in cool fresh waters at temperatures ranging from 10-16℃. 

Their young ones are called troutlets or fry. Their scales are pigmented to help camouflage and avoid predation.

 Why consider eating a trout?

Trout fish is a good source of protein, niacin, vitamin B12, and omega 3 fatty acids. Proteins are the building blocks of our body. They are important in growth and development and aid in repairing damaged tissues.

Niacin is an important component in converting the food we ingested into energy as well as assisting with digestion, skin, and nerve functions within the body. 

Vitamin B12 is essential in the formation of red blood cells which deliver oxygen throughout the body. 

B12 is also essential in supporting brain health and in creating DNA which holds our genetic material. Omega 3 fatty acids are necessary for brain function. They aid in memory, and performance, and assist with growth and development. Research has also shown that omega-3 fatty acids help reduce inflammation and may lower the risk of chronic diseases such as heart disease, cancer, and arthritis.

What are the possible risks of eating stocked trouts?

Due to extensive water pollution and the use of chemicals in feed formulation, stocked trouts may be contaminated by mercury. 

Mercury is a highly viscous metal that is harmful to all animals. When ingested it causes failure of internal organs in the body and finally leads to death. 

In the case of contamination, trout have fewer amounts of mercury. Mercury can be highly poisonous if ingested in large amounts. 

Trouts are becoming unsustainable due to the rise in pollution in water bodies and global warming. 

If you are sensitive to high protein content, you will have to consider other options such as grains that have low protein content. 

How are trouts produced/grown?

Trouts are small fish and can be reared in small aquariums. 

Growing trouts can be done in an aquarium as follows:

  • Preparing the aquarium. The minimal size of the aquarium should be 110-210 liters of water. You should also determine the number of eggs you would want to rear in the aquarium.

    The water is set to temperatures of 10-11℃ this can be achieved by the use of a chiller box. The aquarium should be away from excessive heat and the water should be tested for ammonia and pH levels once a week.
  • Transfer the eggs and grow them. The container containing the eggs should be transported in a cooler box. They are also acclimatized for 15-30 minutes before placing them in a hatching basket. After a while, the weak and infected eggs are removed.
  • Feeding. Now they are all grown. They should be fed 3 times a day. A cleaning solution is applied to the water once a week. After a while, the pinheads are removed. Pinheads are fish that do not feed.
