Sixty experiments were conducted with postlarval and juvenile brown (Penaeus aztecus), white (P. setiferus) and pink (P. duorarum) shrimp at the Marine Fisheries Research Station, Palacios, Texas, from 1969 to 1971. Postlarval and juvenile shrimp were obtained from several sources, stocked at different rates, stocked in various salinity ranges, and fed several types of feeds. The most efficient feeding rates were 7.5% and 10% of the projected body weight of the shrimp disregarding possible mortalities. Growth and survival of juvenile brown and white shrimp was comparable at all salinity ranges,but postlarval brown shrimp exhibited better growth and survival as salinities increased. Production ranged from 2 to 576 pounds per acre in brown shrimp and from 122 to 6l5 pounds per acre in white shrimp. Food conversions ranged from 1.7 to 14. Attempts to "overwinter" sub-adult brown and white shrimp were unsuccessful. Juvenile pink shrimp were able to withstand temperatures as low as 3°C without significant mortalities. Postlarval brown shrimp stocked in early winter survived temperatures of 3 to 4C.
