Are fish considered illegal contraband

Fish can be considered illegal contraband if they are caught or sold in violation of laws and regulations governing fishing, such as overfishing, fishing without a license, or trade of endangered species. Many countries have strict regulations to protect certain fish populations and ensure sustainable practices. Additionally, species like certain types of sharks or sturgeon are often subject to international trade bans under agreements like CITES. Thus, while fish are not inherently illegal, specific circumstances can render them contraband.
