Characterization of Effluent from an Inland, Low- Salinity Shrimp Farm
Aquacultural Engineering 27 (2003) 147Á/156 www.elsevier.com/locate/aqua-online Characterization of effluent from an inland, low- salinity shrimp farm: what contribution could this water make if used for irrigation Dennis McIntosh ,Kevin Fitzsimmons Environmental Research Lab, University of Arizona, 2601 East Airport Drive, Tucson, AZ 85706, USA Received 7 July 2002; accepted 7 October 2002 Abstract Coastal aquaculture can contribute to eutrophication of receiving waters. New technologies and improved management practices allow the aquaculture industry to be more sustainable and economically viable. Current practices, however, do not provide an additional use for effluent water. Nitrogen, phosphorus and other effluent compounds could be valuable plant nutrients. Inflow and effluent water from an inland, low-salinity shrimp farm, were monitored. Bi-weekly analysis included total nitrogen, ammonia-nitrogen, nitrite-nitrogen, nitrate- nitrogen, total phosphorus, reactive phosphorus, alkalinity, chemical oxygen demand (COD), biochemical oxygen demand (BOD), total suspended solids (TSS) and volatile suspended solids (VSS), as well as temperature, salinity, dissolved oxygen and pH. Alkalinity and total nitrogen decreased during the in-pond residency. The other parameters increased while in the ponds. The potential benefit of having nutrient enriched wastewater to irrigate field crops was substantial, supplying between 20 and 31% of the necessary nitrogen fertilizer for wheat production. # 2002 Elsevier Science B.V.

Burbot Management Plan
BURBOT MANAGEMENT PLAN DEPARTMENT OF INLAND FISHERIES AND WILDLIFE DIVISION OF FISHERIES AND HATCHERIES PREPARED BY SCOTT A. ROY ASSISTANT REGIONAL FISHERIES BIOLOGIST REGION E MARCH 2001 BURBOT LIFE HISTORY The burbot, Lota lota (Linnaeus), is a unique member of the cod family. It is the only species in the family, which spends its entire life in fresh water. However, the burbot is similar to its marine relatives in that its distribution is circumpolar. It can be found in cool, fresh waters throughout northern Europe, Asia and North America. In North America its range extends as far south as the northern tier of States across the United States. In Maine, the burbot is commonly known as the cusk, although in other areas it is also called the ling, eelpout, loche and lawyer. Unlike the salmonids and Maine’s other coldwater species, the burbot is not noted for its grace and beauty. The body is elongate, almost eel-shaped, with long, soft-rayed dorsal and anal fins that meet a rounded tail. Although it is smooth and slimy to the touch, the skin is embedded with very small, cycloid scales. The head of the burbot is broad and somewhat flattened. It has a large mouth containing several rows of small teeth on the jaws. A single, whisker-like barbell protrudes from the tip of the chin. There are no obvious external differences between males and females. In general, adults are olive brown to dark brown on the back and sides. This background is overlaid with distinctive patterns of dark brown or black markings and spots. -
Do Some Atlantic Bluefin Tuna Skip Spawning?
SCRS/2006/088 Col. Vol. Sci. Pap. ICCAT, 60(4): 1141-1153 (2007) DO SOME ATLANTIC BLUEFIN TUNA SKIP SPAWNING? David H. Secor1 SUMMARY During the spawning season for Atlantic bluefin tuna, some adults occur outside known spawning centers, suggesting either unknown spawning regions, or fundamental errors in our current understanding of bluefin tuna reproductive schedules. Based upon recent scientific perspectives, skipped spawning (delayed maturation and non-annual spawning) is possibly prevalent in moderately long-lived marine species like bluefin tuna. In principle, skipped spawning represents a trade-off between current and future reproduction. By foregoing reproduction, an individual can incur survival and growth benefits that accrue in deferred reproduction. Across a range of species, skipped reproduction was positively correlated with longevity, but for non-sturgeon species, adults spawned at intervals at least once every two years. A range of types of skipped spawning (constant, younger, older, event skipping; and delays in first maturation) was modeled for the western Atlantic bluefin tuna population to test for their effects on the egg-production-per-recruit biological reference point (stipulated at 20% and 40%). With the exception of extreme delays in maturation, skipped spawning had relatively small effect in depressing fishing mortality (F) threshold values. This was particularly true in comparison to scenarios of a juvenile fishery (ages 4-7), which substantially depressed threshold F values. Indeed, recent F estimates for 1990-2002 western Atlantic bluefin tuna stock assessments were in excess of threshold F values when juvenile size classes were exploited. If western bluefin tuna are currently maturing at an older age than is currently assessed (i.e., 10 v. -

Pinkney U.S. Fish and Wildlife Service Chesapeake Bay Field Office Annapolis, MD and Elgin S. Perry Statistical Consultant Colonial Beach, VA Prepared for Dev Murali Government of the District of Columbia Department of Energy and Environment Washington, DC June 2020 ABSTRACT In 2018 and 2019, the U.S. Fish and Wildlife Service Chesapeake Bay Field Office (CBFO) monitored polychlorinated biphenyl (PCB) and organochlorine (OC) pesticide concentrations in whole body samples of forage fish. Fish were collected along the mainstem Anacostia River, Kingman Lake, five major tributaries, and (as a reference) a section of the Potomac River. Mummichog (Fundulus heteroclitus; referred to as MC in this report) and banded killifish (F. diaphanus BK) were chosen because of their high site fidelity and widespread presence in the watersheds. The objectives are to: 1) establish a pre-remedial baseline of these contaminants in fish from the Anacostia mainstem and major tributaries, Kingman Lake, and the Potomac River; 2) compare total PCB, total chlordane, and total DDT among sampling locations; and 3) interpret patterns in PCB homologs. -
Food Habits of the Southern Channel Catfish (Ictalurus Lacustris Punctatus)

BAILEY 2 Muse•,l, of Zoology, U•ffversity of Michigan,, Ann Arbor M•chigan AND H•u•¾ M. H•umso•, J•. Iowa State Co•servcttion(•ommissio,•, Des Moit•cs, Iowa .•BSTRACT The stmnaeh contents of 912 channel catfish (769 containing food) taken iu a short section of the Des Moines River from September, 1940, to October, 1911, are analyzed. The physical and biotic elmraeteristies of the study area are described; a partial list of the fishes present together xvith comments on their importance and relative abundance is included. The ehanuet eatfish is omnivorous, as is revealed by a review of the pertinent literature and by this study. A wide wtriety of organisms is eaten (some 50 families of insects alone are represented--these are listed). Insects and fish serve as staple foods, plant seeds are taken i• season, and various other items are eaten in limited numbers. The principal groups of foods (insects, fish, plants, and miscellaneous) are anMyzed volumetrically, by œrequeney of occurrence, and numerically. In the area studied, catfish grow at a rate of about 4 inches a year during the first 3 years of life (determined by length-frequency analysis). These natural size groups are utilized to establish the relationship between size and food habits. Young fish feed ahnost exclusively on aquatic insect larvae--chiefly midges, blackflies, mayflies, and enddis flies. In fish frmn 4 to 12 inches lo•g insects continue to make up the bulk of the food, but at progressively greater size larger insects (mayflies and caddis flies) are eaten with increasing frequency and dipterans are of less importonce than in the smaller size group; snmll fish and plant seeds become significant items of diet. -
Invasive Catfish Management Strategy August 2020
Invasive Catfish Management Strategy August 2020 A team from the Virginia Department of Game and Inland Fisheries uses electrofishing to monitor invasive blue catfish in the James River in 2011. (Photo by Matt Rath/Chesapeake Bay Program) I. Introduction This management strategy portrays the outcomes of an interactive workshop (2020 Invasive Catfish Workshop) held by the Invasive Catfish Workgroup at the Virginia Commonwealth University (VCU) Rice Rivers Center in Charles City, Virginia on January 29-30, 2020. The workshop convened a diverse group of stakeholders to share the current scientific understanding and priority issues associated with invasive catfishes in Chesapeake Bay. The perspectives shared and insights gained from the workshop were used to develop practical, synergistic recommendations that will improve management and mitigate impacts of these species across jurisdictions within the watershed. Blue catfish (Ictalurus furcatus) and flathead catfish (Pylodictis olivaris) are native to the Ohio, Missouri, Mississippi, and Rio Grande river basins, and were introduced into the Virginia tributaries of Chesapeake Bay in the 1960s and 1970s to establish a recreational fishery. These non-native species have since spread, inhabiting nearly all major tributaries of the Bay watershed. Rapid range expansion and population growth, particularly of blue catfish, have led to increasing concerns about impacts on the ecology of the Chesapeake Bay ecosystem. 1 Chesapeake Bay Management Strategy Invasive Catfish Blue and flathead catfishes are long-lived species that can negatively impact native species in Chesapeake Bay through predation and resource competition. Blue catfish are generalist feeders that prey on a wide variety of species that are locally abundant, including those of economic importance and conservation concern, such as blue crabs, alosines, Atlantic menhaden, American eels, and bay anchovy.
