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 ...
A metaphase cell positive for the bcr/abl rearrangement (associated with chronic myelogenous leukemia) using FISH. The chromosomes can be seen in blue. The chromosome that is labeled with green and red spots (upper left) is the one where the rearrangement is present. Fluorescence in situ hybridization (FISH) is a molecular cytogenetic technique ...
Hearing, vibration, and the lateral line. Hearing is an important sensory system for most species of fish. For example, in the family Batrachoididae, males use their swim bladders to make advertisement calls which females use to localize males. Hearing threshold and the ability to localize sound sources are reduced underwater, in which the ...
Mahi-mahi. The mahi-mahi ( / ˈmɑːhiːˈmɑːhiː /) [ 3] or common dolphinfish[ 2] ( Coryphaena hippurus) is a surface-dwelling ray-finned fish found in off-shore temperate, tropical, and subtropical waters worldwide. Also widely called dorado (not to be confused with Salminus brasiliensis, a freshwater fish) and dolphin, it is one of two ...
Largehead hairtails are elongated in shape with a thin pointed tail (they lack a fish tail in the usual form). The eyes are large, and the large mouth contains long pointed fang-like teeth. [3] Largehead hairtails grow to 6 kg (13 lb) in weight, [4] and 2.34 m (7 ft 8 in) in length. [2] Most are only 0.5–1 m (1 ft 8 in – 3 ft 3 in) long, [3 ...
A fishmonger (historically fishwife for female practitioners) is someone who sells raw fish and seafood. Fishmongers can be wholesalers or retailers and are trained at selecting and purchasing, handling, gutting, boning, filleting, displaying, merchandising and selling their product. In some countries modern supermarkets are replacing ...
The males do not have to compete with other males, and female anemone fish are typically larger. When a female dies a juvenile (male) anemone fish moves in, and "the resident male then turns into a female and reproductive advantages of the large female–small male combination continue". [22] In other fishes sex changes are reversible.
The lateral line, also called the lateral line organ ( LLO ), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these ...
