Distribution is restricted to institutions or individuals located in particular regions of Canada. However, no restriction is placed on subject matter, and the series reflects the broad interests and policies ofthe Department ofFisheries and Oceans, namely, fisheries and aquatic sciences. Manuscript reports may be cited as full publications. The correct citation appears above the abstract of each report. Each report is abstracted in Aquatic Sciences and Fisheries Abstracts and indexed in the Department's annual index to scientific and technical publications. Numbers 1-900 in this series were issued as Manuscript Reports (Biological Series) of the Biological Board ofCanada, and subsequent to 1937 when the name ofthe Board was changed byAct of Parliament, as Manuscript Reports (Biological Series) of the Fisheries Research Board of Canada. Numbers 1426 - 1550 were issued as Department ofFisheries and the Environment, Fisheries and Marine Service Manuscript Reports. The current series name was changed with report number 1551. Manuscript reports are produced regionally but are numbered nationally. Requests for individual reports will be filled by the issuing establishment listed on the front cover and title page. Out-of-stock reports will be supplied for a fee by commercial agents.

  • 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.

It does not represent a decision by the U.S. Fish and Wildlife Service (Service) on whether this taxon should be designated as a candidate species for listing as threatened or endangered under the Federal Endangered Species Act. That decision will be made by the Service after reviewing this document; other relevant biological and threat data not included herein; and all relevant laws, regulations, and policies. The result of the decision will be posted on the Service's Region 3 Web site (refer to: http://midwest.fws.gov/eco_serv/endangrd/lists/concern.html). If designated as a candidate species, the taxon will subsequently be added to the Service's candidate species list that is periodically published in the Federal Register and posted on the World Wide Web (refer to: http://endangered.fws.gov/wildlife.html).

    NEW YORK Freshwater FISHING2015–16 OFFICIAL REGULATIONS GUIDE VOLUME 7, ISSUE NO. 1, APRIL 2015 Fishing for Muskie www.dec.ny.gov Most regulations are in effect April 1, 2015 through March 31, 2016 MESSAGE FROM THE GOVERNOR New York: A State of Angling Opportunity When it comes to freshwater fishing, no state in the nation can compare to New York. Our Great Lakes consistently deliver outstanding fishing for salmon and steelhead and it doesn’t stop there. In fact, New York is home to four of the Bassmaster’s top 50 bass lakes, drawing anglers from around the globe to come and experience great smallmouth and largemouth bass fishing. The crystal clear lakes and streams of the Adirondack and Catskill parks make New York home to the very best fly fishing east of the Rockies. Add abundant walleye, panfish, trout and trophy muskellunge and northern pike to the mix, and New York is clearly a state of angling opportunity. Fishing is a wonderful way to reconnect with the outdoors. Here in New York, we are working hard to make the sport more accessible and affordable to all. Over the past five years, we have invested more than $6 million, renovating existing boat launches and developing new ones across the state. This is in addition to the 50 new projects begun in 2014 that will make it easier for all outdoors enthusiasts to access the woods and waters of New York. Our 12 DEC fish hatcheries produce 900,000 pounds of fish each year to increase fish populations and expand and improve angling opportunities.

Abstract In this paper the major description, epidemiology, pathogenesis and clinical sign, diagnosis, treatment and control of parasitic crustaceans in fish has been reviewed. The major crustaceans parasites commonly encountered in cultured and wild fish are: copepods (ergasilidea and lernaeidae), branchiura (argulidae) and isopods). Members of the branchiura and isopod are relatively large and both sexes are parasitic, while copepods are the most common crustacean parasites are generally small to microscopic with both free-living and parasitic stages in their life cycle. These parasitic crustaceans are numerous and have worldwide distribution in fresh, brackish and salt water. Most of them can be seen with naked eyes as they attach to the gills, bodies and fins of the host.
