The most important of these are soil type, water quality, species cultured and the type, application method and rate of fertilizers used and all must be carefully considered. Compost is an effective fertilizer for small ponds. not require fertilization. Monitor water chemistry of culture ponds. Pond fertilization should continue until an object cannot be seen 18 inches under the water. Consider the long-term use of ponds before starting a fertilization program. Increasing the growth of microscopic plants (phytoplankton) is the key to increasing fish growth. Typically, infertile ponds still support 40 to 200 pounds of fish per acre, more than most people can use. ... A pond’s nutrient levels influenced by culture history as well as nutrient inputs. Ponds are often fertilized to increase yields of bass and sunfish (bream). Also fish will be in better condition, and the quality of catch by fishermen usually improves. However, not all ponds need added fertilizer or lime. ment, pond fertilization; other considerations include pond renovation, elimination of ex-isting fish populations and re-stocking. General Guide for Pond Fertilization Based on Pond Ecology and Farm Economics The central theme of this book has been the relationship between pond ecology and making cost-effective, intelligent decisions regarding pond fertilization strategies. Application rates for some common grades of fertilizer. When both forms of plankton sink to the bottom, they create an organic ooze which feeds aquatic insects. Aquaculture Pond Fertilization PDF Download. Pond fertilization should begin in March and early April initially or when water temperatures reach 60 °F in South Carolina. Nutrients provided from fertilizer increase production of microscopic plants (phytoplankton) that serve as food for microscopic animals (zooplankton) and aquatic insects. It is generally sold in 5 gal cans. Ponds receiving adequate amounts of fertilizer typically contain 300 to 400 pounds of fish per surface acre. Grant Science Center, Mansfield University, Mansfield, PA, USA. Plankton abundance can serve as a measure of fertilization. After the initial application of fertilizer, managers should wait 10 days to two weeks before establishing whether or not another application of fertilizer is needed. Similarly, pond fertilization can increase fish yields three to four times. A plankton bloom may not develop quickly in the spring in some ponds which receive only phosphate fertilizer. 8. In extreme south Florida, this may translate into a year-round fertilization schedule. Pond Fertilization BMP No. Pond fertilization strategies are locality dependent. POND FERTILIZATION Joe T.

Secchi disc- A pond fertilization tool Visibility Comments < 20 cm Danger of DO problems every night 20-30 cm Plankton becoming too abundant 30-45 cm Ideal 45-60 cm Plankton becoming too scarce > 60 cm Water too clear, inadequate plankton and danger of aquatic weed problem Initiating a fertilization program is recommended only when the pond owner desires more and bigger fish, the pond is not already fertile, and the pond has been properly stocked, Dr. Stone said. One-time or haphazard fertilization is uneconomi-cal and often causes aquatic weed problems. It is also fairly easy to apply. We can provide food for our fish in two different ways: We can give them “artificial” feeds that are prepared either commercially i.e. FERTILIZATION Fertilization increases the capacity of a pond to produce fish.

Place compost material into corrals built of bamboo or wood measuring at least two meters long by one meter wide. Pond fertilization Introduction Just as fish need good water quality conditions to thrive, they also need an abundant supply of food to grow. Unless a pond will be fished more heavi-ly, fertilization to increase fish production is of little value. The size of pond that can be effectively fertilized depends upon the quantity of compost available. Choose a fertilizer high in phosphorus, as it is the most important nutrient in ponds. Pond owners should be committed to a long-term management program before fertilization begins. Microscopic crustaceans (zooplankton) feed on the phytoplankton. Pond owners who want clear water should not fertilize either. Farm Pond Fertilization and Liming Figure 1. nium polyphosphate (10-34-4 or a similar formu-lation) has gained in popularity among pond managers and it is comparable to granular formu-lations in price ($4-$6/gal). The required number of applications during the growing season will vary from one to 10 or more, depending upon the pond’s response to fertilization. in "Introduction to Fish Pond Fertilization" determines how much compost is actually applied. While most individual algal cells can only be viewed using an instrument such as a microscope, algal blooms give color to the pond water. Table 1. Fertilizing catfish ponds Practices Fertilizers may be applied at weekly intervals ifOnly apply fertilizers when necessary to promote phytoplankton blooms. Avoid excessive fertilization by using moderate doses and relying on the Secchi disk visibility to determine if fertilization is needed. In addition, information is provided concerning the economics of different fingerling and grow -out farming practices in … Pond Fertilization and Liming Proper fertilization and liming can increase three to four times the pounds of a pond will support. Figure !.Fertilization increases the abundance of natural food. Fertilizer comes in three forms: liquid, powdered and granular. Monitor growth of larval yellow perch & determine diet selection. RESEARCH work on various phases of pond fertilization and management was begun by this Station in 1934. A fanner measures the effect of fertilization by the abundance of phytoplankton. Deep green color indicates excessive plankton occuJTence. Water sources influence Use of wild water may have both additional nutrients as well as invertebrates.
