More food
Foods with a moisture content between 45-75%, which are prepared from raw materials with high moisture content, such as low-value fish, fish and fishery industry waste, slaughterhouse waste, etc. This type of food is prepared on a daily basis and is mostly consumed by carnivorous fish. including salmon.
Wet foods
Foods with a moisture content between 25-45%, which are prepared from fresh food ingredients and materials such as grain flour.
Semi-moist food
Foods with moisture content between 15-25%, which are less beneficial than raw materials with high moisture content. Wet and moist foods are used as palatable foods in the cultivation of many species because they have a soft texture and relatively good performance. These foods cause some problems and require compliance with the rules. Among these rules, the following can be mentioned:
🔴 They must be transported and stored in the cold so that they don't spoil at the time of consumption. There is little possibility of planning to prepare this type of food. The possibility of contamination of raw materials, especially fishery and slaughterhouse waste, is high. Improper transportation and storage of this type of food causes the loss of some essential substances, including vitamins and certain unstable fats, and creates a suitable place for the spread of fungi and bacteria. These types of foods have an adverse effect on water quality.Dry foods
Dry foods have a moisture content between 7-13%. This type of food is relatively simple to manufacture and transport and can be easily used in large pools. This type of food includes advantages such as various raw materials with special nutritional characteristics. , the possibility of quality control, low cost and food planning, low conversion factor and low volume, etc. Dry foods can be produced in different sizes that suit the needs of different breeding species, and dry foods that have special drugs such as antibiotics can also be produced. biotics or all kinds of hormones and other permitted additives can also be produced. Dry foods can be produced using dry raw materials and a mixture of dry and wet raw materials in the form of flour, pellets, granules, sheets and ... produced. Flour or powder is a simple mixture of crushed dry raw materials that can be turned into a paste or ball shape before feeding to the pool. The dissolved water causes problems in water quality.
