Self Cleaning Larval Culture Tanks

Oceans Design is the sole U.S. manufacturer of commercial self-cleaning tanks for high-density larval culture. Many species of fish larvae require a frequent supply of micro-diet feed to wean them from live feeds to dry diets. The majority of this feed isn't consumed by the larvae and sinks to the tank bottom where it will form large bacterial mats if not cleaned regularly.

Because many species are cultured using green water techniques or clay, it is difficult to see the tank bottom. The only effective cleaning mechanism is by siphoning these tanks which takes an enormous amount of time and results in many viable larvae getting siphoned in the process. Oceans Design's self-cleaning tanks utilize a squeegee that cleans both the sidewall and tank bottom depositing all the debris into a trough extending from the center of the tank to the side wall. This trough is easily siphoned in seconds or a trough squeegee can be added to pull all the debris to a drain valve.

Self cleaning tanks are manufactured as center draining or sidewall draining and in many cases ordered as a hybrid of the two. The center draining tanks utilizes a center standpipe that is stationary and utilizes an air curtain to prevent larvae from getting impinged on the larval screen. The side draining tanks utilize 1-2 ESLIDE LARVAL boxes making screen changes very fast with no loss of larvae. These boxes hang from the inside sidewall of the tank and have an air curtain in front of the screen to prevent larvae from getting impinged on the screen.
