In addition, grass carp should not be stocked when water temperatures drop below 50°F, because most vegetation growth has stopped and the plant has started dying back. Status: Grass Carp have been recorded from 45 states; there are no reports of introductions in Alaska, Maine, Montana, Rhode Island, and Vermont. Their low consumption rate and reduced assimilation efficiency, coupled with elevated metabolic costs, leave little energy available for somatic growth.

Fish in the … Grass carp suppliers will often quit sell grass crap in summer months due to the problems with hauling the fish in high temperatures. High rates of growth of diploid and triploid grass carp are attributed to their “low efficiency‐high volume” energetic strategy, which is quite successful as long as food supplies allow them to feed ad libitum. High survival (86–100%) and satisfactory grass carp growth (47–56 mg) were obtained in the outdoor tanks and cages during the 10–day experiment.
