Print Pin Rate. Crayfish breed like crazy! Producers should weigh all of the factors in their given situation and adjust stocking rates accordingly. Figure 2. Adequate water sources should be available. In addition, when stocking occurs during summer, at least some portion of the mature females should show signs of ovarian development. Lengthy exposure to elevated temperatures, direct sunlight or wind will kill or severely stress broodstock, as will rough handling or contamination with foreign substances such as fuel or chemicals (Figure 1). Then it will start again. To achieve maximum results, stocked crawfish must survive and, if necessary, complete maturity, increase their energy reserves, mate and then burrow successfully. It is easy to obtain them; however you need to be cautious. Breached levees from flood waters can disperse crawfish out of the pond and introduce unwanted fish into the pond. Crayfish (astacoidea) are a favorite food of both largemouth and smallmouth bass and can aid in growing bass to trophy size.They should be stocked at a rate of forty pounds per acre for establishment in ponds with existing bass populations; an ideal strategy is to stock them simultaneously with other supplemental forage species such as golden shiners or threadfin shad, as this spreads out … Stock all sections of the pond and place crawfish directly in the water, not on dry ground. To achieve maximum results, stocked crawfish must survive and, if necessary, complete maturity, increase their energy reserves, mate and then burrow successfully. The crayfish is the largest invertebrate in the pond. A full, fatty and bright yellow or orange hepatopancreas (digestive gland) inside the body of a mature female prior to burrowing indicates the much needed energy reserves for reproduction (left), whereas a small, watery, amber hepatopancreas indicates a less desirable body condition (right). (I might save some for the pot ) My question is there anything I should be carefull about introducing them into their new home? Note, the dark eggs in the ovary of the crawfish on the left – indicating advanced reproductive development. Water replacement and/or flushing may be necessary.

Restocking is often needed following major levee renovation because the most productive broodstock are usually burrowed into the levees in open ponds, and earth moving will often destroy broodstock within their burrows or prevent reemergence in the fall. Stock healthy crawfish (sacrificed individuals generally have bright yellow fat). Levees can also act to keep flood waters out of a crawfish pond at times. There, crayfish can be a liability because they injure minnows when ponds are seined or harvested. In New York and other northern areas, paper shell crayfish are probably the best species of crayfish to stock for pond culture. Harvest Rice in July. Younger crayfish need a different food source than adults. Increased water depth, vegetative cover and shade, or water exchanges are all options for buffering the effects of high water temperatures at stocking. New stockings should occur between April and July. Nitrates are best removed using live plants, which use the chemical as a fertilizer. Good luck! If the owner does not plan to fish for catfish or remove most of them by the time they reach 2 pounds, they should not stock catfish in their pond and focus more on bass, bluegill, and redear sunfish. -Mike, im looking for live brown crawfish that build mud towers for sale I tried looking up pond suppy and biological but did not have any luck please help as I want them for my garden before bad weather comes thanking you in advance katherine, Hello Katherine, I can recommend trying a Louisiana crawfish supplier.

Will crayfish damage the liner? small crayfish, and occasionally small fish. Properly stocked sportfish ponds seldom have burrowing crayfish problems. Generally, ponds which are roughly 25 percent full are suitable for stocking. In established ponds, however, where production occurs in the same location each year, crawfish populations are usually self-sustaining with no need for supplemental stockings, short of some major catastrophe that interrupts the normal life cycle, such as a major die-off (from pesticides or other contaminates) prior to successful burrowing. Successful burrowing depends on critical moisture levels in the soil. To set up a freshwater crayfish farm, start by digging a pond to house your crayfish in and connecting a drainage system to it. Catching crayfish using a rod can sometimes be as much a sport as angling for fish.

But i got some crawfish traps and was gonna try them there. Since crawfish populations tend to be self-sustaining, stocking is usually only needed in new ponds, when a pond has been idle for a season or longer or after extensive levee renovation or other events that disrupt the reproductive process in permanent ponds. 00. To provide crawfish every opportunity to burrow successfully and in optimal conditions, water should remain on the field as long as possible, or feasible, after stocking. Figure 1. -Mike. Conversely, if new ponds have optimal temperatures and oxygen levels, contain sufficient cover to minimise predation and can maintain these conditions for an extended period after stocking, it may be desirable to stock with younger crawfish that are not closely synchronised in their state of maturity. Good luck! The individuals we stock in a pond are intended to be consumed themselves. Suitable broodstock can be obtained from any type of pond or natural habitat as long as the crawfish are in good health and not under undue stress. 30-90 lbs. It is not a spring fed pond.

At least 50 per cent of the crawfish used as stockers should be females (Figure 3). Therefore, stocking during the cooler hours of the day/night or during cloudy/rainy weather is one way to minimise this difference and maximise survival. Although not well documented, it is possible that effective stocking rates may be lowered somewhat when stocking occurs in ponds with permanent levees that already have many old or existing burrows. By mid-summer, the water should have drained from the rice field and the crawfish are in burrows underneath. Crayfish are very hardy and can handle a very wide range of water quality and temperature extremes pretty well. If levee surfaces are completely bare and devoid of cover, artificial cover, such as cardboard, plywood, clumps of hay or corrugated roofing material strategically placed along the perimeter near the water’s edge will enhance successful burrowing. While crawdads are hearty creatures, they can become stressed and refuse to eat if they aren’t in a habitat that makes them feel comfortable. Contrary to rumor, crawfish should always be emptied directly into the water and not onto dry ground adjacent to the water (Figure 2). See Why We're Different. Thanks for checking out the blog!! Be sure at least 50 per cent of females are mature (sacrificed individuals will have yellow to brown eggs). Amount and type of cover, such as vegetation in the pond and at the water’s edge often will affect the number of crawfish surviving and successfully burrowing after stocking. For the most part, population control is one of the most difficult aspects of crawfish production due to, in part, factors that are not under the producer’s control. Hey Mike, You should aim for about 1500 crayfish per hectare or 2.5 acres. I have a 3500 gallon Koi pond with plastic liner. Harvest crawfish May or June Drain pond and repeat cycle (without restocking crawfish) In some locations, ponds cannot be drained and planted with vegetation. Best results are achieved when water temperatures do not differ greatly from the temperature of the crawfish themselves at the time of stocking. Crop rotational systems that employ the field rotation approach are usually stocked in late May, in June or July, when rice plants are large enough to withstand the crawfish without damage and when most needs for harmful pesticide applications have passed – about 45 days post-planting. Cook Time: 4 hours. Pond levels should remain mostly constant, at near normal depths, until a week or so before draining, when water level can be dropped substantially and held at that level until final draining to trigger last-minute burrowing. ...
