Variability In Estimating Abundance Of Postlarval Brown Shrimp, Farfantepenaeus Aztecus (Ives), Migrating Into Galveston Bay, Texas, Geoffrey A. Matthews
Variability In Estimating Abundance Of Postlarval Brown Shrimp, Farfantepenaeus Aztecus (Ives), Migrating Into Galveston Bay, Texas, Geoffrey A. Matthews
Gulf and Caribbean Research
Three sets of monitoring data were used to examine the variability associated with abundance estimation of postlarval brown shrimp, Farfantepenaeus aztecus (Ives) in Bolivar Roads, Texas—the main connection between the Gulf of Mexico and Galveston Bay. Abundance of postlarvae (PL) caught with Renfro beam trawl varied greatly in different years on the same dates. A “spring peak” of brown shrimp PL migrating into Galveston Bay was found for 2 April with a quadratic regression fit to 6-day moving averages of daily mean abundance from 22 yrs of monitoring data: Ln(PL+1) = 0.8736 + 0.09037Day - 0.0004934Day2 (adj-R2 = …
Ex-Vessel Value And Size Composition Of Reported May - August Catches Of Brown Shrimp And White Shrimp From 1960 To 1981 As Related To The Texas Closure, Charles Wax Caillouet Jr., Dennis Brian Koi
Ex-Vessel Value And Size Composition Of Reported May - August Catches Of Brown Shrimp And White Shrimp From 1960 To 1981 As Related To The Texas Closure, Charles Wax Caillouet Jr., Dennis Brian Koi
Gulf and Caribbean Research
Indices were used to test for trends in ex-vessel price spread (value per shrimp by size category), size composition, and ex-vessel value composition of the reported May-August catches (inshore and offshore combined) of brown shrimp (Penaeus aztecus) and white shrimp (P. setiferus) from the Texas coast, the Mississippi River to Texas, and Pensacola to the Mississippi River, from 1960 to 1981. Levels of reported May-August catch and ex-vessel value of the catch also were examined for the same period. Statistical tests were conducted to determine if 1981 was an outlier as compared to other years, in …
Trends In Ex-Vessel Value And Size Composition Of Reported May - August Catches Of Brown Shrimp And White Shrimp From The Texas, Louisiana, Mississippi, And Alabama Coasts, 1960-1978, Charles Wax Caillouet, Dennis Brian Koi
Trends In Ex-Vessel Value And Size Composition Of Reported May - August Catches Of Brown Shrimp And White Shrimp From The Texas, Louisiana, Mississippi, And Alabama Coasts, 1960-1978, Charles Wax Caillouet, Dennis Brian Koi
Gulf and Caribbean Research
Exponential models were used to characterize (1) ex-vessel value (in dollars) per shrimp by size category (count; i.e., number of shrimp per pound, heads off); (2) size composition (expressed as cumulative weight of the catch in pounds, heads off, by size category); and (3) ex-vessel value composition (expressed as cumulative ex-vessel value, in dollars, of the catch by size category) for reported May-August catches (inshore and offshore combined) of brown shrimp (Penaeus aztecus) and white shrimp (P. setiferus) from the Texas, Louisiana, Mississippi, and Alabama coasts (statistical areas 10-21) from 1960 to 1978. Exponents of the …
Technique For Estimating Trawl Efficiency In Catching Brown Shrimp (Penaeus Aztecus), Atlantic Croaker (Micropogon Undulatus) And Spot (Leiostomus Xanthurus), Harold Loesch, James Bishop, Arthur Crowe, Robin Kuckyr, Paul Wagner
Technique For Estimating Trawl Efficiency In Catching Brown Shrimp (Penaeus Aztecus), Atlantic Croaker (Micropogon Undulatus) And Spot (Leiostomus Xanthurus), Harold Loesch, James Bishop, Arthur Crowe, Robin Kuckyr, Paul Wagner
Gulf and Caribbean Research
Mark-recapture experiments conducted in a small 17.5 ha lake in Barataria Bay, Louisiana, were used to estimate the efficiency of a 4.9-m (16-foot) otter trawl in capturing brown shrimp, Atlantic croaker, and spot in water 1.5 m deep. The trawl was observed to sweep an area 2.5 m in width. Trawl efficiency was determined to be approximately one-third to one-half for brown shrimp, one-fourth for Atlantic croaker, and only 6 percent for spot.
A Study On The Growth Rate Of Brown Shrimp (Penaeus Aztecus Aztecus Ives, 1891) From The Coasts Of Veracruz And Tamaulipas, Mexico, Ernesto A. Chávez
A Study On The Growth Rate Of Brown Shrimp (Penaeus Aztecus Aztecus Ives, 1891) From The Coasts Of Veracruz And Tamaulipas, Mexico, Ernesto A. Chávez
Gulf and Caribbean Research
The present study was undertaken with the purpose of getting the proper basis for exploiting brown shrimp resources in a rational manner, by introducing control regulations of fishing activities. The growth rate models are necessary for the other parameters of population dynamics of the stocks of this species, whose annual catch, Osborn, Maghan and Drummond (1969), averages 54 million pounds of tail weight, representing 52% of the total shrimp caught in the Gulf of Mexico. This shows that Penaeus aztecus aztecus is the most important of shrimp species exploited in this region. Nevertheless, the brown shrimp is the least well …
