Differences and benefits of farmed and marine fish
All types of fish have the necessary characteristics to improve people’s health and are introduced as healthy food. In general, marine fish are richer in mineral salts and vitamins than freshwater fish.
In the world, the consumption of farmed fish has become more popular than marine fish due to the assurance of compliance with technical and sanitary principles and systems under human control, because with the economic growth of countries and industrialization and water pollution, the possibility of the presence of heavy metals and toxins, especially mercury, in fish meat. Therefore, the tendency of consumers towards farmed fish has increased.
Gholamhossein Akbari stated: Despite the fact that the consumption of fish, especially the farmed type, has increased in the city of Tehran, it seems that due to ignorance, some people look at farmed fish with doubt, and it is thought that they are given hormones for the growth of these fish. Injected or their feed is manure and excrement.
He added: It should be noted that not only hormones are not used in the country to increase the growth of fish, unlike some products, but from an economic point of view, they try to use as much as possible the natural potential and nutrients in the water for the growth of fish.
Akbari continued: In order to help the food reserves of Chinese carp fish, which generally feed on tiny creatures called plankton in the water, we are trying to enrich the water of the pool with various fertilizers to enable the growth of plankton to feed more fish in the sunlight. .
This aquaculture expert stated: the whole art of the breeders in breeding these fish is the balance between the amount of food in the pool and the nutritional needs of these fish; Therefore, the inefficiency of breeders will only lead to an increase in the consumption of primary inputs such as fertilizer and an increase in costs.
Akbari reminded: In the world, the consumption of farmed fish is more popular than marine fish due to the assurance of compliance with technical and sanitary principles and systems under human control. Because with the economic growth of countries and industrialization and water pollution, the possibility of the presence of heavy metals and toxins, especially mercury, in fish meat increases and leads consumers to farmed fish.
He pointed out: It seems that nowadays, with the expansion of societies, the scientific observance of the process of production, distribution and consumption, which takes place in the form of a marketing management, is more important. Therefore, whenever you take a fish out of the water, it is not fresh because you have to be sure of the health of the water. Also, the stages of catching until supply should be done based on scientific and health principles in order to have a correct choice of healthy fish.
