Fish living on coral reefs where carbon dioxide seeps from the ocean floor were less able to detect predator odor than fish from normal coral reefs, according to a new study.
Two new species of weakly electric fishes from the Congo River basin are described in the open access journal ZooKeys. One of them, known from only a single specimen, is named "Petrocephalus boboto." "Boboto" is the word for peace in the Lingala language, the lingua franca of the Congo River, reflecting the authors' hope for peace in troubled Central Africa.
Sharks are highly-evolved killing machines and a new study published in the open-access journal PLOS ONE has compiled a comprehensive picture of how these marine predators hunt – from start to finish.
Female fruit flies with a large number of sexual partners are playing an invaluable role in preventing the extinction of males, research at the University of Liverpool has shown.
Florida Pond Management of Orlando Florida developed a method of using mosquito fish as well as common aquarium fish like: guppies, swordtails, mollies and white cloud mountain minnows, to control
Though present in more than 6,000 living species of fish, the adipose fin, a small appendage that lies between the dorsal fin and tail, has no clear function and is thought to be vestigial.
Researchers from the University of Hawaii and the University of Tokyo are gaining novel insights into how one of the most feared and least understood ocean predators swims, eats and lives — all courtesy of instruments strapped onto and ingested by sharks.
In the Baltic Sea, two cod stocks evolve independently. Also the juveniles of two economically important flatfish species, flounder and plaice, live there within limited space. This is possible due to the irregular distribution of water masses of different salinity in this inland sea.
Archaeological data indicate modern herring management needs to take a longer look into the past to manage fisheries for the future says a new study involving Simon Fraser University researchers.
With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean. However, a team of researchers has found that their abundance could be at least 10 times higher.
The prowfish (Zaprora silenus) is a subtropical species of a perch-like fish found in the northern Pacific Ocean. The range of the prowfish is from the Aleutian Islands, Alaska to Kamchatka, Russia, from Navarin Canyon in the Bering Sea to Hokkaido, Japan and Monterey, California. The preferred habitat of the prowish is rocky bottom at a maximum of 2,200 feet in depth where they spend most of their adult life. Prowfish can grow to a length of 40 inches or more having an elongated body that...
The Bluefish (Pomatomus saltatrix) is the only living species of the family Pomatomidae. It is a marine pelagic fish that can be found around the world in temperate and subtropical waters, except for the northern Pacific Ocean. Bluefish are known as tailor in Australia, shad on the east coast of South Africa, and elf on the west coast. Other common names regarding this fish are blue, chopper, and anchoa. It is a good eating and game fish. The bluefish is moderately proportioned with a...
Ichthyology is the study of fish that focuses on many types of fish including cartilaginous fish, jawless fish, and skeletal fish. This branch of zoology can be associated with marine biology and fisheries science, as well as other areas of study. Ichthyologists, those who practice ichthyology, have discovered more than 32,200 species of fish, and it is thought that they discover 250 new species each year. Humans first began to study fish during the Upper Paleolithic Revolution, when humans...
The little tunny is found widespread in temperate and tropical waters of the Atlantic Ocean, Black Sea and Mediterranean Sea. It is the most common tuna and is highly migratory, with a range from Cape Cod, Massachusetts to Brazil in the Western Atlantic. In the Eastern Atlantic it is found from Skagerrak to South Africa. The little tunny will form schools close to the shoreline, around inlets, and sandbars that can cover up to two miles. This fish prefers warm water and will migrate south in...
Image Credit: WA Djatmiko/Wikipedia (CC BY-SA 3.0, 2.5, 2.0 and 1.0) The African sharptooth catfish is native throughout Africa, and the Middle East, and in the 1980’s it was introduced all over the world. This catfish lives on muddy bottoms in freshwater lakes, rivers, swamps, man-made habitats, and occasionally found in urban sewage systems. This species is able to crawl across dry ground to another body of water when one pool dries up. It is also able to survive for long periods of...
