RECOMMENDATIONS: Staff recommends that the City enter into a MOU with Icicle Seafoods for the purpose of installing and operating a fish pump under the dock and at the dewatering and tote loading station on the North trestle of the Homer Fish Dock. The term of the contract will be three years with two one-year options.
Fill the fish pump water reservoir tank with a hose or bucket until it overflows.

This article is subjective. All goldfish are different and can tolerate different conditions - much like humans. Therefore, some goldfish may be able to live in a bowl with any pump or oxygen, and others may not be able to sustain such conditions. I had a goldfish live for eight years in a regular bowl without any air pump and throughout it's life it was active and healthy. After it died, I replaced the water and bought a new goldfish. I kept the new one at the same conditions I kept the old one - it died after a week. You never can predict the lifespan of a goldfish or how to care for it; it's not one size fits all. Don't overthink things: feed it, clean the bowl every few days, keep it in water (obviously), and hope for the best. Remove the standpipe from harvest pond to allow for the transfer of shrimp through the fish pump.

At the University of Florida shrimp demonstration facility (UF/IFAS IRREC), protocols have been established for effective use of a fish pump to harvest juvenile and adult Pacific white shrimp, Litopenaeus vannamei, from ponds and raceways. These protocols can reduce time and labor costs, improve product quality, and can be used with other aquatic organisms.Also remember not to put the air pump directly on the top of yourfish tank, or to put it on a shelf that hangs off the fish tank, asthis will transfer these vibrations into the fish tank (in addition tomaking them louder in the room), and this can be very irritating toyour fish.The fish pump we tested was a gasoline powered Heathro fish pump which consisted of a Honda GX270 motor, a 2.5 gallon (9.5 L) gasoline tank, an industrial priming pump and two 6-inch (15.2 cm) camlock fittings for attaching hoses to the top and side of the round fiberglass housing (Figure 1). The fiberglass housing of the pump contains a single-vane cast aluminum impeller designed to prevent damage to the shrimp during transfer. This unit is mounted on a cart equipped with two handle bars and pneumatic wheels for manual mobility (Figure 1). The cart design allows farmers to use other accessories such as a dewatering tower and/or holding tanks to help improve the harvest process.That depends on what you mean. If you have a that is run by an air pump, then theair pump is necessary, as without it the filter will not operate andyou are not going to be gaining benefit from having that filter onyour fish tank.Several companies manufacture and market fish pumps and there are various models and sizes available. The University of Florida shrimp demonstration facility only evaluated the Heathro fish pump. A list of some currently available fish pumps and accessories is provided in the appendix.Some aquarium air pumps are quieter than others but they all make noise. All air pumps have moving parts inside, so naturally, the motor makes sounds. It is possible, however, to lessen the noises the pump makes through simple, quick fixes and easy maintenance tasks. This is important to remember, as too much noise is detrimental to the fish.
