  1. Frog Production Aquaculture Unit 6 Lesson 2

  2. Objectives • List problems associated with frog production • Describe the requirements of frog products. • Compare diets of tadpoles to those of frogs

  3. Questions?

  4. Species that are used in production • Bullfrog most popular species for commercial production • Adults may be 8 inches long and weigh as much as 2 lbs

  5. Habitat of frogs • Native to the US east of the Rocky Mountains • Shorelines of marshes, swamps, creeks, rivers, lakes and ponds.

  6. Seedstock and breeding • Tadpole ponds can be stocked with wild-caught or commercial frogs • Bullfrogs lay eggs in shallow water during March and June • Eggs hatch in 4 days up to 3 weeks depending on temperature • Under cultural operations, tadpoles need constant aeration

  7. Culture Method • Metamorphosis from tadpole to frog, 5 months-2 years. • see life-cycle chart in text. • Adult bullfrogs only eat live, moving food • 1/4 to 1/2 pound market weight may require a year • Need separate ponds for tadpoles and adults

  8. Culture Methods cont. • Ponds should be shallow, but provide food, shelter and hibernation areas • Tadpole ponds should have high algal production • Carnivorous fish must be removed from pond • Ponds must be fenced with a top to reduce predators

  9. Stocking Rate • 1 inch frog length per gallon of water

  10. Feeding • Tadpoles fed indirectly by algae growth through pond fertilization • Adult frogs must have moving food, such as earthworms, flies, crickets and other living frogs • Some producers feed artificial diets

  11. Diseases • Hot weather increases chance of diseases • Producers must regularly inspect, disinfect facilities and cull sick frogs

  12. Harvesting • Frogs are harvested by hand, hook, net or spear

  13. Processing and Marketing • Whole live frogs can be sold for research • Hind legs are marketed to restaurants
