On a weekday morning, Johnnie Heal caught four largemouth bass from a pier in Clearlake Oaks, but tossed three back in the water.
“I don’t eat anything out of this lake,” said Heal, 32, who likes fishing for sport. “They say you can eat so many a month. But if you have to put a limit on it, I’m not going eat it.”
But the fourth bass he gave to an elderly woman who wanted it for her meal.
Because of high mercury levels in Clear Lake fish, women older than 45 and all men should eat only one serving per week of largemouth bass, according to guidelines issued by California’s Office of Environmental Assessment.
Warnings and guidelines, which are posted at public boat ramps, are less restrictive for other species such as carp, crappie, bluegill and catfish, allowing for several servings per week.
But women of child-bearing age and children are advised not to eat any largemouth bass at all out of Clear Lake and to limit consumption of other fish to only one serving per week.
There are similar warnings for many of the state’s other lakes and streams.
