Trout do best in spring water because it keeps a constant temperature, while catfish need a strong flow, about 80 litres per second for every 0.4 hectares of raceway. A backup water supply should be positioned so, if the water supply or pump fails, it can flow by gravity into the start of the raceway. [16]
One way to achieve this is to combine hydroponic horticulture and water treatment, see below. The exception to this rule are cages which are placed in a river or sea, which supplements the fish crop with sufficient oxygenated water. Some environmentalists object to this practice.

Washing meat or cleaning meat is a technique of preparation, primarily used to treat raw meat or poultry prior to cooking in order to sanitize it. Several methods are used which are not limited to rinsing with running water (or with the use of a strainer) or soaking in saltwater, vinegar, lemon juice, or other acids, which may also enhance flavor when cooked.
Once your hard-boiled eggs are done cooking, let them cool for 10-15 minutes before transferring them to a bowl of ice water. Submerging your hard-boiled eggs in ice water ensures that the insides ...
An effective method of preserving the freshness of fish is to chill with ice by distributing ice uniformly around the fish. It is a safe cooling method that keeps the fish moist and in an easily stored form suitable for transport. It has become widely used since the development of mechanical refrigeration, which makes ice easy and cheap to produce.
