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
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.

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
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
Methods of emptying traps vary within the industry. Producers with ponds smaller than a few acres do not use motorized boats because of the added expense.
If ponds are shallow, traps can be emptied by harvesters who walk along while pulling a small boat. One person can empty about 400 traps per day.

Red claw eggs go through several identifiable stages during development. The length of development varies depending on water temperature. The stages are identified by colour changes and appearance of body structures in the developing embryo.
The sequence of development stages and approximate timing at 82o F is:
