Stocking Strategies For Production Of Litopenaeus Vannamei (Boone) In Amended Freshwater In Inland Ponds, Bartholomew W. Green Jan 2008

Stocking Strategies For Production Of Litopenaeus Vannamei (Boone) In Amended Freshwater In Inland Ponds, Bartholomew W. Green

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The performance of the Pacific white shrimp Litopenaeus vannamei (Boone) under various stocking strategies was evaluated in earthen ponds filled with freshwater amended with major ions. Six 0.1-ha earthen ponds located in Pine Bluff, Arkansas, USA, were filled with freshwater in 2003 and 2004, and potassium magnesium sulfate added to provide 50 mg K+ L-1 and stock salt added to provide 0.5 g L-1 salinity. In 2003, three ponds either were stocked with PL15 shrimp (39 PL m-2) for 125 d of grow out or with PL25 shrimp for a 55-d (23 PL …

Evaluation Of Aerial Cluster Sampling Of Double-Crested Cormorants On Aquaculture Ponds In Mississippi, Brian S. Dorr, Loren W. Burger Jr., Scott C. Barras Jan 2008

Evaluation Of Aerial Cluster Sampling Of Double-Crested Cormorants On Aquaculture Ponds In Mississippi, Brian S. Dorr, Loren W. Burger Jr., Scott C. Barras

USDA Wildlife Services: Staff Publications

Concern over increasing numbers of double-crested cormorants (Phalacrocorax auritus) and their impacts on channel catfish (Ictalurus punctatus) aquaculture has resulted in increased need for quantitative information to develop and evaluate depredation management efforts. We evaluated aerial surveys in a stratified cluster sampling (SCS) design to estimate and monitor abundance of cormorants on catfish aquaculture ponds in the Yazoo River Basin of Mississippi, USA (hereafter Yazoo Basin). Twice monthly abundance estimates and coefficient of variation during winter averaged 8,128 (n = 29, SE = 1,233) and 33% (n = 29, SE = 0.02), respectively. Counts of cormorants …
