> ‘[f]ish’ means a wild fish, mollusk, crustacean, invertebrate, amphibian, or part, spawn, or ovum of any of those animals.” (Stats. 2015, ch. 154, § 5.)
Ordinarily, you read statutory terms in a list in the context, including in the context of the other terms. See: https://www.law.cornell.edu/wex/ejusdem_generis
> Ejusdem generis (ee-joose-dem gen-ris) is a Latin phrase that means “of the same kind.” The statutory and constitutional construction principle of “ejusdem generis” states that where general words or phrases follow a number of specific words or phrases, the general words are specifically construed as limited and apply only to persons or things of the same kind or class as those expressly mentioned. For example, if a law refers to automobiles, trucks, tractors, motorcycles, and other motor-powered vehicles, a court might use ejusdem generis to hold that such vehicles would not include airplanes, because the list included only land-based transportation.
While “invertebrate” can be a more general term, in the surrounding context it’s clearly meant to refer to marine invertebrates, not invertebrates in general.
