A diet of newly hatched Artemia (five nauplii/L/day) and dry postlarval feed (50% protein) is fed at 10 to 25 percent of the total body weight per day (bw/d) for the first 5 days after stocking. Then the feed rate is reduced to 7.5 percent bw/d and the feed is changed to a 40% . . . → Read More: Intensive pond production For Bait Shrimp

Post-larvae are removed from larval- rearing tanks and concentrated for counting, packing and shipping. Shrimp PL are shipped at densities of 1,000 to 2,000 per L in polyethylene bags containing seawater (30 to 35 ppt) that is saturated with oxygen and cooled to 18 °C (64.4 °F) before packing. The bags are usually packed . . . → Read More: Zero Exchange Intensive Nurseries For Bait Shrimp The live bait shrimp industry in the southeastern U.S. is dependent on three shrimp species: the Atlantic white shrimp (Litopenaeus setiferus), the Gulf brown shrimp (Farfantepenaeus aztecus) and the Gulf pink shrimp (F. duorarum). All three species occur along the southern and eastern U.S. coasts from Texas through North Carolina. The live bait . . . → Read More: Bait Shrimp Culture Annual yields in small experimental ponds have consistently been 1,800 to 2,300 pounds per acre (2,017 to 2,578 kg/hectare), although some lower and higher yields have been recorded. Recent results from large commercial ponds verify that these yields can be expected. The monthly proportional distribution of annual yield is presented in Table 3. Individual . . . → Read More: Expected Annual Yields From Semi-Intensive Production of Red Swamp Crawfish Harvest generally begins in late March or early April of the year following initial stocking. Trapping is the principal harvest method, but seining can be done when conditions warrant. In deep ponds, boats are needed for efficient trapping. Boats should be able to maneuver among substrate (see section on substrate). Commonly used traps . . . → Read More: Harvesting Red Swamp Crawfish Grown In Semi-Intensive Ponds Existing ponds do not need to have a food source added before stocking because natural foods should be sufficient to sustain the population until the first young of the year (those hatched during successive spawnings of a calendar year) are produced in mid-fall. However, new ponds should be organically fertilized (with cracked corn, cotton . . . → Read More: Feeding Strategies For Semi-Intensive Production Of Red Swamp Crawfish |
