This 16th-century fish stall shows many traditional fish products. The term fish processing refers to the processes associated with fish and fish products between the time fish are caught or harvested, and the time the final product is delivered to the customer. Although the term refers specifically to fish, in practice it is extended to cover ...
Fish preservation is the method of increasing the shelf life of fish and other fish products by applying the principles of different branches of science in order to keep the fish, after it has landed, in a condition wholesome and fit for human consumption. [1][2] Ancient methods of preserving fish included drying, salting, pickling and smoking.
For the most recent several decades, the political goals in fisheries management of commercially important species have been rapidly evolving, primarily driven by (1) a recognition of the response of fish and other target animals to changing climate, (2) new technologies for fishing particularly on the high seas, (3) development of competing ...
Tree traversal. In computer science, tree traversal (also known as tree search and walking the tree) is a form of graph traversal and refers to the process of visiting (e.g. retrieving, updating, or deleting) each node in a tree data structure, exactly once. Such traversals are classified by the order in which the nodes are visited.
According to the Food and Agriculture Organization (FAO), a total of 156.2 million tons of fish, crustaceans, molluscs, and other aquatic animals were captured in 2011. This is a sum of 93.5 million tons of wild animals and 62.7 million tons of farmed animals. 56.8% of this total was freshwater fish, 6.4% diadromous fish, and 3.2% marine fish, with the remainder being molluscs, crustaceans ...
Echo sounding or depth sounding is the use of sonar for ranging, normally to determine the depth of water . It involves transmitting acoustic waves into water and recording the time interval between emission and return of a pulse; the resulting time of flight , along with knowledge of the speed of sound in water, allows determining the distance ...
For cameras that can only focus on one object distance at a time, depth of field is the distance between the nearest and the farthest objects that are in acceptably sharp focus in the image. [1] ". Acceptably sharp focus" is defined using a property called the "circle of confusion". The depth of field can be determined by focal length, distance ...
Aquacultural engineering is a multidisciplinary field of engineering and that aims to solve technical problems associated with farming aquatic vertebrates, invertebrates, and algae. [1] Common aquaculture systems requiring optimization and engineering include sea cages, ponds , and recirculating systems. [ 2 ]
