#2483, "Hubb's WSB Hatchery"
|
A couple weeks ago I went on a tour with allcoast, of the Hubb's Sea World Research Institute, where they raise the white seabass for the tagging program and release from the growout pens. It was really awesome. They had four huge tanks in the back of the "warehouse" each one with 50 big old broodstock seabass. Some of em were 60, 70lbs. The had another tank of the same size with a couple black seabass of like 70, 80lbs. Those things were soooo cool. They were like big old labradors. They'd come up to the glass and look at you and just look out of the window. It was cool. The wsb in the tanks are triggered to breed by controlling the amount of light on the tank (lenght of days) and temperature of the water to create a spring time. That way one of the four tanks is always in spring and they always have eggs. Once the eggs are fertilized, they float to the top of the water (and only the fertilized eggs float) and are sucked into a pipe which dumps into a separate container with a canvas "strainer". The water soaks throgh and is re-circulated, while the eggs stay in the canvas bag. From there they're collected, put into test tubes, made sure they're fertilized and transfered into separate tanks where they hatch. When they are born, and develop mouths, they are fed brine shrimp larvae and when they reach a couple inches long are separated by size and placed into tanks with other fish of the exact same size to discriminate cannibalism. Then, they are fed pellets with all the necessary vitamins and minerals until they reach 8" long at which time they are implanted with the tags and put into growout pens, up and down the coast, where they are released. So, here's some pix-
Here's a couple shots of the baby seabass larvae. They looked like little pollywogs or pond creatures rather than seabass-

Here's some bigger ones. 6-8"

These are the broodstock. I put my hand on the glass in some of the shots for size reference. Keep in mind the fish are about 4-5ft. behind the glass, too. BTW, it wasn't that dark in the tanks, just the way the pix came out.
