What is the maximum number of quarts of smelts that can be kept alive in a day?

The correct answer is based on the regulations regarding the possession of live smelts. In Maine, the legal limit allows an individual to keep up to 2 quarts of live smelts in a day. This limit is put in place to manage and conserve fish populations, ensuring that fishing practices remain sustainable and that smelts can continue to thrive in their natural habitat.

By allowing a maximum of 2 quarts, regulations help regulate the fishing activity and prevent overharvesting, which can negatively impact ecosystems. This limit is applicable for recreational purposes, reflecting the importance of responsible resource management. Maintaining such limits is key in preserving the fishery for future generations, as well as ensuring that current fishing practices do not disrupt the balance of aquatic life.

Other options either underestimate or overestimate the amount that can be typically kept, as well as not acknowledging the specific limits set within Maine's regulations for smelts.
