Embodiments of the present disclosure describe an aquaculture environment control system comprising one or more control apparatuses positioned within a vessel at an angle relative to a proximal vessel wall and configured for scouring of the vessel, wherein each control apparatus has a discharge conduit and each discharge conduit has one or more orifices; and a fluid source in fluid communication with each of the control apparatuses. Embodiments of the present disclosure describe a method of controlling an aquaculture environment comprising supplying one or more of a fluid and gas to a control apparatus positioned within a vessel at an angle relative to a proximal vessel wall; and discharging one or more of the fluid and gas from the control apparatus at a fluid velocity sufficient for scouring of the vessel.

A system for monitoring marine animals includes a monitoring tag attachable to a marine animal. The monitoring tag includes a processor, a memory coupled to the processor, at least one communication interface, and at least one sensor. The processor is configured to store readings from the at least one sensor in the memory. The system also includes at least one communication receiver having a processor, a memory coupled to the processor, and at least one communication interface. The at least one communication receiver is configured to float in water. The processor of the monitoring tag is configured to determine, using the at least one sensor, whether the monitoring tag is within a communication range for radio frequency communication with the at least one communication receiver, and to transmit, via the at least one communication interface of the monitoring tag, the stored readings to the at least one communication receiver responsive to the processor of the monitoring tag determining that the monitoring tag is within the communication range for radio frequency communication with the at least one communication receiver.

A method of culturing an aquaculture of an aquatic animal species of interest is disclosed. The method comprises inoculating the aquaculture with bacteria of at least one genera selected from the group consisting of Pseudomonas, Limnohabitans, Janthinobacterium, Stenotrophomonas, Aeromonas, Acinetobacter and Morganella, wherein the bacteria are provided in an amount sufficient to increase the survival and/or weight of the aquatic animal, thereby culturing the aquaculture of the aquatic animal species.

The present invention relates to a method for preparing a tropical fish feed by using brine shrimp, and a tropical fish feed prepared thereby, and, more specifically, to: a method for preparing a tropical fish feed by using brine shrimp, and a tropical fish feed prepared thereby, the method feeding spirulina and Haematococcus to hatched brine shrimp to prepare a tropical fish feed, and thus can promote the growth of tropical fish, boost the immune system and improve the consumption, digestion, absorption and palatability for tropical fish.
