Not to be confused with "ocean vegetation", this is a code-word for marijuana --- i.e., "c" weed, with "c" standing for "cannabis".
It's widely known that many commercial fishermen bring in "something other than fish" during many of their offshore hauls; to both avoid arousing suspicion among the authorities AND secretly convey to their cohorts that they "have the goods", they claim to be hauling "c-weed" as a side-business to their regular Pisces/crustacean-based harvesting.
