The Diversity of the Brains of Ray-Finned Fishes
Brain, Behavior and Evolution, 2023Brains are very plastic, both in response to phenotypic diversity and to larger evolutionary trends. Differences between taxa cannot be easily attributed to either factors. Comparative morphological data on higher taxonomic levels are scarce, especially in ray-finned fishes.

Evolution and diversity of fish genomes
Current Opinion in Genetics & Development, 2003The ray-finned fishes ('fishes') vary widely in genome size, morphology and adaptations. Teleosts, which comprise approximately 23600 species, constitute >99% of living fishes. The radiation of teleosts has been attributed to a genome duplication event, which is proposed to have occurred in an ancient teleost.

Exotic fishes and freshwater fish diversity
Zoos' Print Journal, 2000The freshwater aquatic biodiversity is depleting alarmingly due to the introduction of exotic species and other anthropogenic activities. The indiscriminate transfer of exotic fishes has brought about a wide array of problems including extirpation of indigenous species. The exotics compete with the indigenous species for food, habitat and may even prey

Diversity of Fish-Associated Flavobacteria of Michigan
Journal of Aquatic Animal Health, 2013Abstract Flavobacteriosis poses a serious threat to wild and propagated fish stocks alike, accounting for more fish mortality in Michigan and its associated state fish hatcheries than all other pathogens combined. Although this consortium of fish diseases has primarily been attributed to Flavobacterium psychrophilum, F. columnare, and F.

Patterns and processes in reef fish diversity
Nature, 2003A central aim of ecology is to explain the heterogeneous distribution of biodiversity on earth. As expectations of diversity loss grow, this understanding is also critical for effective management and conservation. Although explanations for biodiversity patterns are still a matter for intense debate, they have often been considered to be scale ...

Fish Diversion in Hydropower Intake
Journal of Hydraulic Engineering, 1987Hydraulic model studies were conducted to develop a fish screening system to be used in the turbine intakes of Wanapum Development and Priest Rapids Development on the Columbia River, Washington. The system studied utilized a mechanical screen, installed through one of the gate wells, to produce a flow pattern that would deflect downstream migrating ...

Fishes : diversity and fisheries
2012This contribution reviews the knowledge on fish diversity and fisheries in Lake Kivu, with an emphasis on the biology and stock assessment of the introduced Tanganyika sardine, Limnothrissa miodon . Lake Kivu is famous, compared to the other African great lakes, for its poor fish fauna, with 29 species comprising a.o.

Lakes Victoria and Kyoga had many fish species, which were important as food for local population and valuable in scientific studies. Over the past twenty years, the diversity of fish in these lakes had declined due to over-exploitation, introduction of new fish species including the piscivorous Nile perch and degradation of fish habitat.
