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...
A commercial aquaponics system. An electric pump moves nutrient-rich water from the fish tank through a solids filter to remove particles the plants above cannot absorb. The water then provides nutrients for the plants and is cleansed before returning to the fish tank below.
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 ...

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.
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
Bluestreak cleaner wrasses clean to consume ectoparasites on client fish for food. The bigger fish recognise them as cleaner fish because they have a lateral stripe along the length of their bodies, and by their movement patterns. Cleaner wrasses greet visitors in an effort to secure the food source and cleaning opportunity with the client.
