Description
You?ll learn strategies and tactics that can be used to improve production and efficiency in the propagation of fingerlings in fertilized hatchery ponds. This book covers the production of a variety of fish, as well as shrimp, and provides a framework for a systems approach to management decisionmaking. Chapters present information that can be used to improve ecological efficiencies and the economics of production. Strategies and Tactics for Management of Fertilized Hatchery Ponds explains the systems approach to management. In the future, the most effective hatchery managers will base management decisions on information that is site- and pond-specific. This book provides you with needed information on organic and inorganic fertilizer materials; dynamics of water quality; pond filling schedules; biological control of problem organisms; fingerling production of walleye, striped bass, paddlefish, largemouth bass, and others. Readers find solutions to several common problems and learn about the processes needed to solve others.Chapters help answer questions important to the success and effectiveness of management of fertilized hatchery ponds such as:
- What kinds or sources of nutrients should be purchased?
- How much time and water are needed before larvae are stocked?
- What density and age of fish should be stocked?
- How can a satisfactory quality of larvae and environmental variables be achieved so that fish survive stocking and initiate normal feeding and growth?
- Has the initial survival and growth been satisfactory, or should the pond be drawn down and restocked?
- What kind and how much fertilizer should be added to a given pond?This book provides you with information essential for making hatchery ponds as effective and efficient as possible. Whether you?re a fish hatchery manager, student of aquaculture, or agency or academic researcher involved in hatchery management, you will find Strategies and Tactics for Management of Fertilized Hatchery Ponds an indispensable guide for your daily work and studies.
