Baited remote underwater video (BRUV) is a system used in marine biology research. By attracting fish into the field of view of a remotely controlled camera, the technique records fish diversity , abundance and behaviour of species.
A laboratory study with zebra mbuna and ocellate river stingray has demonstrated that these fish can add and subtract 'one' from 2, 3, or 4. The fish had to learn that if presented with, say, 3 yellow symbols, then in a subsequent choice test between 2 and 4 symbols they had to choose 2 to get a food reward (thus, yellow meant "choose one less ...
A United States Fish and Wildlife Officer works in the forensics laboratory. Wildlife forensic science is forensic science applied to legal issues involving wildlife. Wildlife forensic sciences also deal with conservation and identification of rare species and is a useful tool for non-invasive studies.
Marine biology studies species that live in marine habitats. Most of the Earth's surface is covered by ocean, which is the home to marine life. Oceans average nearly four kilometers in-depth and are fringed with coastlines that run for about 360,000 kilometres. [4] [5] Marine biology can be contrasted with biological oceanography.
The Burnham laboratory was established in 1953 as the Ministry's first-ever purpose-built fisheries laboratory. The role of the laboratory was expanded in 1957 to cover work on pollution, and by the mid-60s began to take the lead in the investigation of environmental protection problems, with the exception of those arising from radioactive ...
Student's t-test, Analysis of variance, Mann–Whitney U test Repeated measures design A research design that involves multiple measures of the same variable taken on the same or matched subjects either under different conditions or over two or more time periods.
Fish physiology is the scientific study of how the component parts of fish function together in the living fish. [2] It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish anatomy and physiology complement each other, the former dealing with the structure of a fish, its organs or ...
Ichthyology is the branch of zoology devoted to the study of fish, including bony fish (Osteichthyes), cartilaginous fish (Chondrichthyes), and jawless fish ().According to FishBase, 33,400 species of fish had been described as of October 2016, with approximately 250 new species described each year.
