Abstract: A novel and unique apparatus is disclosed for use in aerating water held in a container, such as a livewell in a fishing boat. The aeration apparatus receives fresh water through a conventional water distribution system, aspirates ambient air into the water, and discharges the mixture of fresh water and aspirated air within the livewell at a location substantially below its water level. Air is aspirated into the fresh water by means of a housing mounted above the water level in the livewell. The housing includes a main passageway through which the fresh water passes and an aspirating port in the housing wall which puts the main passageway in communication with ambient atmosphere above the livewell. A discharge tube receives the mixture of fresh water and aspirated air from the housing and directs it to a plurality of discharge ports positioned substantially below the livewell water level.

Abstract: A distribution system for filling a baitwell in a boat includes a low pressure pump and a dual check valve. The fluid flow into the system is divided so that the pressure on the pump is reduced, thus enabling the use of an inexpensive pump. The check valve permits the influx of fresh water without the need for recirculating the existing water in the baitwell and also prevents backflow from the baitwell.
Abstract: An inexpensive fluid flow indicator capable of use in low flow conditions in a variety of environments, including but not limited to laboratory, industry, and medical applications. Flows are visually indicated by the rotation of balls loosely retained in a longitudinal passageway of the indicator's transparent housing by a flow guide and an outlet port. The flow guide imparts a circumferential or transverse direction to the axial flow of the fluid which causes the balls to revolve about the center line of the indicator.
