Abstract: A depuration process is employed for removing off-flavor contaminants from fish through an advanced oxidation process. Before the fish is harvested, the fish is transferred to a depuration tank or zone containing water. Off-flavor compounds leach from the tissue of the fish into the water in the depuration tank or zone. The water in the depuration tank or zone is circulated through an advanced oxidation reactor that, through an oxidation process, reduces the concentration of the off-flavor contaminants in the water.

Abstract: A device and method are provided for enhancing the feeding response of larval fish to feedstock. A food distribution mechanism is positionable above the tank housing the larval fish and is adapted for receiving the feedstock therein. The food distribution mechanism selectively deposits portions of the feedstock into the tank. A light source is positionable adjacent the tank and selectively directs a laser beam at the tank. A controller is operatively connected to the food distribution mechanism and the light source. The controller is configured to actuate the food distribution mechanism for a time period at selected intervals such that the food distribution mechanism deposits a portion of the feedstock into the tank during each time period. In addition, the controller is configured to actuate the light source for at least a portion of each time period.

Abstract: Methods and compositions for increasing the growth rate of a prey fish are described. A method includes contacting the prey fish with a water-soluble growth promoting factor in an amount effective to increase the growth rate of the prey fish. The water-soluble growth promoting factor can be released through fish skin from the urine and/or feces of a predator fish that has eaten a prey fish. An aquaculture growth supplement includes a carrier and a water-soluble growth promoting factor. Also included are methods of making aquaculture growth supplements.

Abstract: A photoelectrocatalytic oxidizing device having a photoanode being constructed from a conducting metal such as Ti as the support electrode. Alternatively, the photoanode is a composite electrode comprising a conducting metal such as Ti as the support electrode coated with a thin film of sintered nanoporous TiO2. The device is useful in methods for treating an aqueous solution such as groundwater, wastewater, drinking water, ballast water, aquarium water, and aquaculture water to reduce amounts of a contaminant. The method being directed at reducing the amount and concentration of contaminants in an aqueous solution comprising providing an aqueous solution comprising at least one contaminant, and, photoelectrocatalytically oxidizing the contaminant, wherein the contaminant is oxidized by a free radical produced by a photoanode constructed from an anatase polymorph of Ti, a rutile polymorph of Ti, or a nanoporous film of TiO2.

Abstract: A system and method for removing fouling from a photoelectrocatalytic oxidation assembly is provided. The method includes resetting a first counter, increasing the first counter by a first channel increment value, and determining if the value in the first counter exceeds a value corresponding to the number of channels provided in the assembly. If the first counter does not exceed the number of channels, the polarity in a channel associated with the value in the first counter is reversed, and a first timer is reset. If an amount of time in the first timer does not exceed a first time period, the first timer is increased by a first time increment until the time remaining in the first timer exceeds the first time period and the polarity reversal is terminated, returning to the step of increasing the first counter by a first channel increment value.
