(Red) Abalone Fishing Regs -- Ready for Revision?A news item in the latest issue of California Diving News mentioned that the Calif. Dept. of Fish and Game is considering reducing the daily limit of abalone to two per day (it is currently four per day). According to a Fish and Game biologist that replied to Jean Lundeen's inquiry about the proposal: "The number of small (sub-legal) abalone is greatly
reduced from previous years. At the same time, there has been a concentration
of fishery effort in Sonoma and Mendocino Counties during the past decade.
The scarcity of juveniles and increased fishing effort could lead to significant
population declines in the future if immediate action is not taken." Send your comments to: RAACSuggestions@abcamp.com White Abalone Listed as an Endangered SpeciesHip hip hooray! White abalone were declared an endangered species on May 29 by the National Marine Fisheries Service. Don't worry, you won't accidentally collect one while diving for reds. White abalone live at depths of 100 or more feet, and due to overfishing they are few and far between. The ruling makes any harvest of white abalone a federal offense--harvesting whites was already against state law--and it makes federal money available for programs to save the species. White Abalone Sex a SuccessOn April 23, scientists succeeded in coaxing white abalone to mate in the first white abalone captive breeding in 30 years. At UC Santa Barbara, the scientists set the abalone in individual containers, dimmed the lights and added hydrogen peroxide, an abalone aphrodisiac developed for spawning red abalone. A couple of hours later, two of the females had spawned about 3 million eggs each. Shortly after, one of the males released sperm. The scientists added sperm from the male to the two batches of eggs and watched as more than 95 percent of the eggs were fertilized and developed normally, the next day, into free-swimming larvae. Next, scientists will settle the larvae onto plates with red algae and then attempt to raise a fraction of them to adults.
