Book Description
"Closed shedding systems have a place within North Carolina's blue crab fishery if fishers work to understand how to maintain water quality. The advantage of moving away from waterfront property without sacrificing shedding success makes this system design attractive. Key points to remember if you decide to construct a system are: [1] Design the system for the maximum number of tanks to be used. Consider not only current, but also future growth plans. Tanks can always be added, but purchasing larger pumps and/or filters later will substantially reduce profits. [2] Retain additional water in the system. More is better when it comes to water. Oversize the sump to increase overall water quality. [3] Water chemistry must be understood to operate any closed crab shedding system, however designed. Monitor dissolved oxygen, nitrite and ammonia levels more aggressively during the active season. Keep a log for water quality maintenance records to help identify problems before and after they occur. [4] Stock the system slowly. New shedding systems require a lead time of four to six weeks before adding crabs. "Shock loading" of peeler crabs almost certainly causes unnecessary crab deaths."--Summary.
Design and Operating Guide for Aquaculture Seawater Systems

Book Description
This book provides, in one place, basic information and considerations necessary to plan, build and operate seawater systems for culturing purposes. It provides design, construction and operations guidance for seawater (salinities from freshwater to brine) systems with flow rates of 10-1,000 gallons (40-4,000 liters) per minute. While the book concentrates on general circumstances, situations and concepts, comprehensive referencing of text and annotated bibliographies are provided in critical technical areas to allow readers to pursue specialized areas of interest. This upgraded and expanded Second Edition contains a considerably increased number of numerical examples relative to the first edition to demonstrate practical applications of the concepts and presented data.
