A system of harvesting sea creatures from a trench holding the sea creatures in seawater, including a trench, an injection well, and a harvesting apparatus that extracts the sea creatures from the trench. The trench includes a gate at one end of the trench. The gate insertable into an opening at the end of the trench to prevent seawater from entering or exiting the trench and removable from the opening to allow the seawater to enter or exit the trench. The injection well is positioned external to the trench and can receive the seawater discharged from the trench. The harvesting apparatus includes a conveyor that inclines. The conveyor includes a conveyor belt and a wedge at one end of the conveyor that contacts the bottom floor of the trench when the conveyor is inclined.

Method and system for underwater hyperspectral imaging of fish comprising hyperspectral imaging of a fish freely moving in an observation area and identifying and classifying physiological properties of fish or identifying and classifying on identified fish.

System and methods for monitoring the growth of an aquatic plant culture and detecting real-time characteristics associated with the aquatic plant culture aquatic plants. The systems and methods may include a control unit configured to perform an analysis of at least one image of an aquatic plant culture. The analysis may include processing at least one collected image to determine at least one physical characteristic or state of an aquatic plant culture. Systems and methods for distributing aquatic plant cultures are also provided. The distribution systems and methods may track and control the distribution of an aquatic plant culture based on information received from various sources. Systems and methods for growing and harvesting aquatic plants in a controlled and compact environment are also provided. The systems may include a bioreactor having a plurality of vertically stacked modules designed to contain the aquatic plants and a liquid growth medium.

A water treatment and recirculation system includes means to transport water flows at required pressures, a mechanical filter of approximately 100 microns to capture coarse particles, oxygen production means, autonomous electricity generation means, and variable control means using a PLC that administers parameters such as pressure, oxygen and CO.sub.2 levels, flows, pH, etc. The system also includes means to ultrafilter and remove particles of up to 0.02 microns, the purpose being removing organic material macromolecules, disinfecting bacteria and viruses with mechanical removal, and eliminate harmful contaminants such as ammonia, degasifying means to eliminate CO.sub.2 with a multitubular exchanger with membranes made of hydrophobic materials and micro perforations to take CO.sub.2 away to an extraction gas in atmospheric or vacuum conditions; and means to oxygenate water with a multitubular exchanger having membranes constituted by hydrophobic materials and microperforations that inject O.sub.2 into water of a gas under atmospheric conditions.

An agricultural unit includes a tank system that is adapted to provide a combined aquatic environment for raising aquatic animals in aquaculture and for cultivating plants in hydroponic culture and an electrochemical device. The tank system releases excretions of the aquatic animals directly into the aquatic environment so as to produce nutrients for the plants while the electrochemical device is operable in an electrolysis mode to produce hydrogen and oxygen while consuming electrical energy provided by a source of electrical energy and is further operable in a fuel cell mode to produce electrical energy and heat by oxidizing the produced hydrogen. The electrochemical device is operatively coupled to the tank system so as to transfer at least part of the produced heat and the produced oxygen to the aquatic environment.

An apparatus and system is disclosed for facilitating an angler in placing fish into a weigh-in bag from a boat's live well. The apparatus includes a post for inserting into a seat post receiver of a boat, and has a hook on its top for receiving handles of a weigh-in bag. The apparatus also preferably includes a fill tube connected to the pumping system of a boat's live well plumbing system. The apparatus holds and fills the bag in a position and location convenient to allow an angler to use both hands to retrieve a fish from a live well and then insert the fish into the bag.
