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.

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. -

Know Your Cod and Pollock Products
School of Fish - Explores frozen processing methods, Exposes deceptive processing practices, Educates on common species and Equips the sales professional with an arsenal of tools designed to combat the issues vulnerable to deception. KNOW YOUR COD AND POLLOCK PRODUCTS Raw material handling determines product quality: • Top quality cod and pollock products come from a variety of gear types and freezing methods. • Line-based gear such as longline submits fish to less potential damage, resulting in better quality. • At-sea freezing, heading and gutting is even more important for cod and pollock than for other species due to the problems of belly burning and gall bladder staining. • Belly burning may occur if the viscera are not removed promptly after catch. Hydrochloric acid may escape from the stomach and burn the meat, resulting in reduced recoveries. • Gall bladder staining may occur if the fish is not frozen soon after catch. If left unfrozen, the gall bladder may burst within one or two days of catch. Bile stains result in reduced recoveries. • The following matrix plots quality between gear types and freezing methods: Shore frozen Freezing Frozen at sea (FAS) Longline of Good quality Excellent quality Pot catch Average quality Good quality Method Trawl Check that the fish was properly bled: • A pinkish hue in the flesh suggests poor bleeding and is a mark of inferior product. • An orange hue suggests that the fish was poorly bled and then frozen twice. Learn to recognize inferior quality products: • It is important for seafood buyers to distinguish between superior and inferior quality product. • Differentiate superior products from inferior by one or a number of the following characteristics. -
