Cleaning symbiosis is known from several groups of animals both in the sea and on land (see table). Cleaners include fish, shrimps and birds; clients include a much wider range of fish, marine reptiles including turtles and iguanas, octopus, whales, and terrestrial mammals.
With 1,100 linear feet of space, the pier also provides covered platforms for protection from the elements, a fish-cleaning table, and some of the best angling in the state. Unlike many other...
PCBs are organochlorine compounds with the formula C 12 H 10−x Cl x; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. [2] Because of their longevity, PCBs are still widely in use, even though their manufacture has declined ...
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.
Conservation. The process of conservation and restoration of plastics requires an understanding of chemical composition of the material and an appreciation for the possible methods of restoration and their limitations, as well as development of a post-treatment preventive care plan for the object.
Aspidontus taeniatus. Quoy & Gaimard, 1834. The false cleanerfish ( Aspidontus taeniatus) is a species of combtooth blenny, a mimic that copies both the dance and appearance of Labroides dimidiatus (the bluestreak cleaner wrasse), a similarly colored species of cleaner wrasse.
Self-cleaning can sometimes be achieved if the fish stocks density is sufficiently high and the water level is sufficiently low. For example, if trout are stocked at 20 kilograms per cubic metre, they can keep the raceway unit clean by their swimming movements, preventing waste solids from settling to the raceway floor.
The crimson cleaner fish (Suezichthys aylingi), or butcher's dick in Australia, is a species of wrasse native to the southwestern Pacific Ocean around Australia and New Zealand. This species inhabits patches of sand on reefs at depths of from 6 to 100 metres (20 to 328 ft). It is a cleaner fish.
Using the Parshall flume free flow equation, determine the discharge of a 72-inch flume with a depth, Ha of 3 feet. From Table 1: Throat width = 72 in = 6 ft, C = 24, and n = 1.59. Q = 24 Ha 1.59 for a 72-inch Parshall flume. So, if there is a depth of 3 feet, the flow rate is ≈ 140 ft 3 /s
