Device for cooling a livewell

A method for managing a temperature of a livewell comprising:

• regulating the temperature of the livewell using temperature regulation components of a modular apparatus;
• receiving a first signal from a sensor;
• determining whether the first signal corresponds to one of a plurality of errors statuses;
• deactivating the temperature regulation components in response to determining that the first signal corresponds to one of the plurality of error statuses, wherein the temperature regulation components include at least one of a compressor, a condenser, and an evaporator;
• determining whether a second signal indicates that the one of the plurality of error statuses has cleared;
• and
• reactivating the temperature regulation components in response to determining that the second signal indicates that the one of the plurality of error statutes has cleared.

A system comprising:

• a modular apparatus comprising:
• a self-contained fluid line;
• a first fluid line in communication with the self-contained fluid line and configured to provide fluid communication between the modular apparatus and the livewell;
• a condenser in communication with the self-contained fluid line;
• and
• a controller,
• wherein the self-contained fluid line comprises an expansion valve in fluid communication with a compressor,
• wherein the controller is configured to communicate with a temperature probe that detects a temperature of water in the livewell and control at least one of the condenser, compressor, and expansion valve to cause the temperature of the water in the livewell to reach a desired temperature;
• and
• a fishing vessel comprising:
• the livewell;
• a second fluid line;
• an entry port on a fishing vessel, wherein the entry port allows water from a body of water to enter a second fluid line;
• an exit port connected to the second fluid line that expels water from the second fluid line out into the body of water.
