Answer Details
The question is asking for a by-product of fish that is NOT listed among the options.
The correct answer is "leather", as it is not typically considered a by-product of fish.
Fish by-products are often obtained from processing fish for food or other uses. Fish meal, fish silage, glue, and oil are all examples of common by-products of fish. Fish meal is a high-protein supplement used in animal feed, while fish silage is used as a fertilizer or soil conditioner. Fish glue can be used as a wood adhesive or in the manufacture of paper, and fish oil is commonly used as a nutritional supplement for humans and animals. However, leather is not typically produced from fish, making it the correct answer to the question.
