Abstract: An apparatus and method for dispensing bait fluid such as fish oil at a substantially uniform rate into water surrounding a trap to attract crustaceans such as crabs or shrimp. The apparatus includes a cylindrical housing (108) closed with end caps (106, 114), to store the bait fluid, and a normally open port for filling the housing with the bait fluid. A plurality of orifices (112) are formed in the lower end cap (114) for dispensing the bait fluid into the water surrounding a crab trap. Additionally, the apparatus may include a flow restrictor (116) for controlling the flow rate of the bait fluid through the orifices. A positioner (110) is provided for fixing the flow rate restrictor in place inside the dispenser housing. One of the end caps (106) is removable for providing access to the interior of the housing. A normally closed valve (102) may be included for releasing trapped air during the filling of the dispenser housing with bait fluid.
