Previously, the  website consisted of only one page and lacked details of the fish diagnostics  conducted at the laboratory. There are now 67 pages which highlight the many  aspects of fish health operations in Region 3. Julie Teskie has been working on the site to  increase public awareness on the issues of fish health, and improve the  intra-agency flow of information.  A  major addition to the website is the section on fish bacterial, viral, fungal  and parasitic diseases. It includes descriptions of the disease signs and  pathology of significant fish diseases, as well as species affected and  commonly applied treatments. Another new feature is the National Wild Fish  Health Survey section that highlights the history and statistics of the survey  and includes links that detail the species surveyed and the agencies involved. Other sections include pages  with information on our staff, current news, and the Fish Health Short Course.  There is also a photo album and a “contact us” page. Most pages are illustrated  with photos of employees engaged in fish health activities.  I encourage everyone to view the new website  at: http://www.fws.gov/midwest/LaCrosseFishHealthCenter/  Modern Air' Aerators AREA has been a global leader in providing water quality solutions for   industries including Aquaculture, Public Aquariums/Zoos, Wastewater, Golf   Courses, Ponds/Lakes and more.

We have termed this new form of information dissemination the "Aquaculture Drug Update."  Unlike our Newsletter and Website, each Aquaculture Drug Update will be a highly focused, concise encapsulation of an important event relating to a specific aquaculture drug or aquaculture drugs in general.  Updates will target end-user aquaculturists and will include such information as: a notice of a new drug approval, notification of important regulatory changes and a new source of aquaculture drug-related information. Each Update will be offered in a variety of file formats (i.e., pdf, MS Word, MS Publisher and xps).  We encourage you to freely transmit any Update (or the content of any Update) to anyone.  If you choose to extract the information from an Update and, as an example, insert it into a newsletter, please be sure to include the entire content, including reference to the source of the information and a link to the actual Update. Below is the content of the first Aquaculture Drug Update (dated 22 December 2008) published by AADAP.  This, and all future Updates, will always be available at the following page on our website: http://www.fws.gov/fisheries/aadap/Aquaculture_Drug_Update.htm **American Fisheries Society – Aquatic Animal Drug Approval Partnership (AADAP) 
      Newly Updated “Aquaculture Drug-use Guidance” Poster** The U.S. Fish and Wildlife Service’s AADAP Program and the American Fisheries Society’s Fish Health and Fish Culture Sections recently published, in limited quantities and for limited distribution, an “Aquaculture Drug-use Guidance” poster.  The poster was developed to better facilitate the dissemination of information regarding aquaculture drugs and their approved uses.  The large-format laminated poster outlined all aquaculture drugs currently approved by FDA for use in the USA, and described permitted aquatic species, diseases or conditions, treatment regimens, and withdrawal periods. Interest in the poster was overwhelming and in very short order we ran out of copies to distribute.  But help has arrived - FDA’s Center for Veterinary Medicine has assisted us in publishing a new batch of posters, which are now available free of charge.  This new printing has been updated to include a couple of very recent new approvals or label expansions, and will be printed with a different background color to allow one to quickly distinguish it from the earlier version.

The database, called "Animal Drugs @ FDA," is a  publicly-accessible web-based application available through the CVM home page. "Animal Drugs @ FDA" replaces the "Database of  Approved Animal Drug Products," or ―Green Book, a database that was previously  developed and managed by the Virginia-Maryland Regional College of Veterinary  Medicine Drug Information Laboratory at Virginia Tech   University. This new application allows users to search for detailed  descriptions of all FDA-approved new animal drugs. The search tool not only  allows users to conduct simple word searches, but is also capable of more  complex searches through the following eight specific search criteria:  NADA/ANADA, Sponsor, Ingredients, Proprietary, Dose Form, Route, Species, and  Indication. Under the Generic Animal Drug and Patent Term Restoration Act,  CVM will continue to make available electronic files of listed drugs previously  provided through the Green Book on its web site.

Time to Fertilize Those Ponds Part 1: Submitted by: Greg Fischer, Northern Aquaculture Demonstration Facility I have attached a basic recipe that we have been following the last  few years. It seems to be working and producing some really good  plankton blooms. I would also mention that periodically the ponds need to be  scraped (due to the alfalfa meal), or weeds can become a problem. We  also physically remove any weeds we see in the ponds as soon as possible to prevent  them from spreading. **Initial  fertilization** (approx. April 20, depending on weather) 400       pds Alfalfa meal or Soybean meal
      18       lbs/1.7 gal  liquid Urea (28-0-0       nitrogen)
      1.0 lb       phosphate(0-45-0 liquefied)
      Spread       organic fertilizer before filling, spray liquid inorganic fertilizer into       water  **Standard  fertilization** (approx. every week or as needed)(verify with seechi disk  readings and plankton sample tows). 100       lbs alfalfa meal or soybean meal
      3.0       lbs Urea
      0.5       lbs phosphate
      applied       through June, as long as plankton bloom is needed  Part 2: Submitted by: Paul Christel, Lac Courte Oreilles Band of Lake Superior Chippewa Our pond fertilization is on the dynamic end of the  spectrum.  Some reasons for this include  the following: We       draw surface water from a lake and water conditions vary.
      Ponds       are earthen.  If a slow drawdown is       used in the fall, we probably get a boost from “bugs” that went dormant.
      Plankton       is collected and put out into the ponds. This is done somewhat on an “as       needed” basis, but also depends on how much time we have to collect.
      We do       not stock fry at a high density.        Since 2004, we have reduced fry stocking by 50%.  This has not affected production and       seems to make the plankton last longer. These factors tend to reduce our dependence on  fertilization.  Producers using well  water with lined ponds, for example, need to use far more supplementation.  All the variables aside though, there is a  basic schedule we tend to not stray too far from.  Variability is addressed more with  supplemental plankton stocking than fertilization.  Our base fertilization plan uses alfalfa meal  and torula yeast (no inorganic fertilizers) as follows: At        pond filling, 100 pounds alfalfa meal and 50 pounds yeast per acre.
        Weekly        thereafter, 50 pounds alfalfa meal and 25 pounds yeast per acre.  We tend to reduce the yeast amount as        the weeks pass. This simple approach has been working quite well.  Remember though, we “cheat” by stocking  plankton.  This is about the simplest  fertilization plan I’ve heard of.  **Evaluation of Yellow Perch Grow Out in a** **19°C Water Recirculating System** Submitted by: Greg J. Fischer, Northern Aquaculture Demonstration Facility **Abstract**
        Yellow  Perch (*Perca flavescens*) is an  important commercially raised coolwater species in Wisconsin  and the Midwest. Yellow perch, of various  strains, are raised for food markets and stocking uses utilizing outdoor ponds  and recirculating water systems.  Growing  yellow perch to a market size in 10-12 months is critical for the aquaculture  market in the Midwest.  A pilot study to evaluate the effectiveness  of combining early pond rearing and utilizing RAS systems for grow-out to meet  this market was undertaken by researchers at the University of  Wisconsin-Stevens Point Northern Aquaculture Demonstration Facility (NADF).  NADF acquired Lake Mendota  strain, pond raised, fingerling (127 mm avg.) yellow perch (monosex female and  mixed sex fish) to evaluate hatchery production attributes (i.e., husbandry,  growth, physiological condition, feed efficiency, survival, water chemistry  requirements and body condition factor) in an elevated temperature (19° C)  recycle aquaculture system.  The monosex female  fish outperformed the mixed sex fish during 190 days of rearing in the  system.  Specific growth rates of Lake Mendota  monosex female fish in the RAS averaged 0.53mm/day and 0.58g/day and the mixed  sex fish averaged 0.25mm/day and 0.33g/day.   Tank densities in the RAS at harvest were 26 kg/m3 for the mixed sex  fish tank and 44 kg/m3 for the monosex fish tank. Average feed conversion for  the monosex fish was 1.5 and 2.7 for the mixed sex fish.   Measured total ammonia nitrogen (NH3+NH4)  and nitrite nitrogen (NO2-N) levels ranged from 0.0 - 0.26mg/L.  Calculated unionized ammonia (NH3-N) levels did not exceed the  published “safe” level of 0.05 - 0 .1 mg/L.   Measured tank temperatures averaged 19oC  and ranged from 9.0-22.0o C.  Measured dissolved oxygen concentration in  RAS tanks averaged 7.8mg/L and ranged from 1.9 -12.0mg/L.  Baseline alkalinity averaged 120mg/L, pH  averaged 7.7 and ranged from 6.5-8.2.  Carbon  dioxide concentration averaged 35mg/L and ranged from 20-63mg/L.
      It does appear from this initial research project that Lake Mendota  monosex female yellow perch can outperform Lake Mendota  mixed sex yellow perch in an elevated temperature water (19oC) recirculating system  and that 127mm (TL) fall pond fingerlings can be reared successfully indoors  for market in 190 days.  **Return
