The Hubbs-SeaWorld Research Institute is normally about rearing marine food fish. This year, they have a project to see how well they can use their skills and knowledge to rear tropical marine ornamental species.

They recently completed the installation of eight 250L tanks supplied by a heated and sterilized flow thru water supply. Flame angelfish (Centropyge loricula) and bicolor angelfish (Centropyge bicolor) were stocked into the tanks and the broodstock are setting up homes. While they wait, three Southern CA display aquariums are collecting eggs for larval rearing discovery.

The effort is expected to create a cascade of unique challenges at HSWRI related to feed requirements and optimizing rearing conditions. Fortunately, many general husbandry practices are transferable among species and the Rising Tide Conservation community of researchers operates in a very collaborative fashion.


Special Projects Manager


Federico José Rotman has been working in the field of marine fish culture for over 20 years. In 2001, he completed a master’s degree from the University of Miami’s Rosenstiel School of Marine and Atmospheric Sciences and has been involved with commercial and research marine fish aquaculture since. His experience with ornamental fish includes working with various species of pygmy angelfish and yellow tang. Between 2001 and 2003, while employed at Black Pearls Inc, (Kona Blue Water Farms), he was an integral member of a team that successfully spawned and produced flame angelfish (Centropyge loriculus) utilizing the marine calanoid copepod (Parvocalanus crassirostris) as a primary life feed. Beyond his work with ornamental fish, he has extensive experience with the culture of other marine species including Yellowfin tuna (Thunnus albacares), almaco jack (Seriola rivoliana), California halibut (Paralichthys californicus), California yellowtail (Seriola lalandi), cobia (Rachycentron canadum), white seabass (Atractoscion nobilis), Pacific red snapper (Lutjanus guttatus) and giant grouper (Epinephelus lanceolatus). Federico has been a commercial hatchery manager, a researcher and is currently the Special Projects Manager at Hubbs-SeaWorld Research Institute.

Kevin Stuart


HSWRI Research Scientist


Kevin Stuart has a broad background and successful history of spawning and rearing various marine finfishes on the east and west coasts of the United States.  Kevin obtained his master’s degree in aquaculture, fisheries and wildlife from Clemson University.  After leaving Clemson, he began working the South Carolina Department of Natural Resources (SCDNR) in Charleston, SC as a research biologist.  While at the SCDNR, Kevin was part of the red drum (Sciaenops ocellatus) stock enhancement program, helped to initiate the black sea bass (Centropristis striata) and cobia (Rachycentron canadum) larval and juvenile rearing projects, and assisted with summer flounder (Paralichthys lethostigma) rearing.  In 2003, he came to Hubbs-SeaWorld Research Institute and has since been focused on improving larval and juvenile rearing for multiple species including: California yellowtail (Seriola lalandi), California halibut (Paralichthys californicus), white seabass (Atractoscion nobilis), yellowfin tuna (Thunnus albacares) and California sheephead (Semicossyphus pulcher).
