The paper develops a model of world frozen shrimp market using data from 1980 to 2004. There is a structural change in the world shrimp market that shifts the market volume from traditional to the non-traditional markets. Market structural change affects shrimp price significantly. Shrimp price has a trend and...
Limited resource catfish producers are seeking ways to enhance economic and financial profitability of their aquaculture enterprises. One of the recommended methods to increase profitability is to sell value added smoked catfish at niche markets. Development of value-added smoked catfish is a potential cottage industry for limited resource catfish farmers...
Chromosomal rearrangements may complicate construction of Arabidopsis with multiple TDNA-insertion mutations. Here, crossing two lines homozygous for insertions in AtREV3 and AtPOLH (chromosomes I and V, respectively) and selfing F1 plants yielded non-Mendelian F2 genotype distributions: frequencies of +/++/+ and 1/1 2/2 progeny were only 0.42 and 0.25%. However, the...
A high prevalence of vertebral deformities has been observed in various fishes, especially cyprinids, from certain regions of the Willamette River for many years. One proposed source of these deformities is exposure to toxicants. Histological evaluation of affected chiselmouth Acrocheilus alutaceus revealed that all lesions associated with vertebrae were associated...
A spectrum-matching and look-up-table (LUT) methodology has been developed and evaluated to extract environmental information from remotely sensed hyperspectral imagery. The LUT methodology works as follows. First, a database of remote-sensing reflectance (R[subscript]rs) spectra corresponding to various water depths, bottom reflectance spectra, and water-column inherent optical properties (IOPs) is constructed...
