New Weakly Electric Fish Species Reflects Hope For Peace In Central Africa
2014-04-11 14:05:39

Pensoft Publishers 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. On a 2010 field trip to the Congo River of Democratic Republic of the Congo, in the riverside village of...

Promiscuous Female Fruit Flies Prevent Male Extinction
2014-04-02 17:14:08

University of Liverpool 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. Scientists have found that flies in the northern parts of the United States are more inclined to have multiple partners in order to reduce the occurrence of an X chromosome which causes the production of only female offspring. This selfish genetic element (SGE) tries to replicate...

Adipose Fins Evolve Repeatedly In Teleost Fishes
2014-03-05 10:33:13

University of Chicago 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. However, a new study analyzing their origins finds that these fins arose repeatedly and independently in multiple species. In addition, adipose fins appear to have repeatedly and independently evolved a skeleton, offering a glimpse into how new tissue types and structural...

Shark's Eye View Of The Ocean
2014-03-01 05:42:24

April Flowers for redOrbit.com - Your Universe Online 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. The sharks were outfitted with sophisticated sensors and video recorders to measure and see where they are going, how they are getting there, and what they do once they reach...

Fate Of Fish Stocks In The Baltic Sea Determined By Salt Stratification
2014-02-19 15:39:07

GEOMAR Helmholtz Centre for Ocean Research Kiel Why management strategies must take into account regional conditions 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. Scientists of GEOMAR Helmholtz Centre for Ocean Research Kiel and the Institute of...

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. That is one of the key findings in the study, just published online in Proceedings of the National Academy of Sciences (PNAS). SFU researchers Iain McKechnie, Dana Lepofsky and Ken Lertzman, and scientists in Ontario, Alberta and the United States are its co-authors. The study is one of many...

Mesopelagic Fish Biomass Is 10 Times Higher Than Estimated
2014-02-10 06:40:49

Spanish National Research Council (CSIC) The stock of mesopelagic fish changes from 1,000 to 10,000 million tons 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 with the participation of the Spanish National Research Council (CSIC) has found that their abundance could be at least 10 times higher. The results, published in Nature Communications journal, are based on the acoustic...

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...

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...

Little tunny, Euthynnus alletteratus
