This parasitic round worm, Philometra incognita, was discovered and named only recently (2015) by FWRI biologists and their colleagues. It is commonly found in the gonads of gag grouper. It occurs on both the Florida Atlantic and Gulf coasts, and probably reaches sexual maturity at about the same time that the host fish is spawning. Parasitic nematodes of the family Philometridae can cause significant damage to the gonads of wild and cultured marine fish, and FWC researchers are studying how P. incognita may be affecting the reproductive success of gag grouper in the Gulf.
Because fish parasites can react in a number of different ways to environmental conditions or changes, scientists are also hoping to learn whether these worms can be used as an indicator of ecosystem health. This can be accomplished, in part, by comparing the prevalence of P. incognita and its effects on host fish both inside and outside of the Madison-Swanson Marine Protected Area in the northeast Gulf waters. If the parasites can help to indicate ecosystem health, then they may be useful in identifying regions in the Gulf that could use more attention.
FWRI scientists in the Marine Fisheries Biology group who study fish reproductive dynamics are conducting a three-year Marine Fisheries Initiative (MARFIN) study assessing male abundance and the factors affecting the reproductive potential of gag grouper in the eastern Gulf. Researchers need to capture these fish in order to study them, which provided a unique opportunity for our fish health team to obtain and examine samples from adult female gag for a specific parasite found in the ovaries.
Gag grouper are caught on hook-and-line from a charter boat in the Gulf. The gonads of female gag are brought back to the lab in St. Petersburg for analysis.

Escaped or stocked grass carp and black carp can negatively affect native fish and mussel species and their habitats. The LaCrosse Fish Health Center (WI) works with states and USGS and university researchers to determine potential for establishment of self-sustaining populations of grass carp and black carp.
The gag grouper (Mycteroperca microlepis) is a popular reef fish in Florida, and it is the most widely distributed of all Florida grouper species. Given the popularity and importance of this fishery within the state, the FWC is dedicated to learning more about gag and the factors affecting this important fishery.
The National Wild Fish Health Survey (NWFHS) was initiated by Congress in 1997 to stem the depletion of wild fish populations. Wild fish populations were being devastated by diseases like Salmonid Whirling Disease, and at the time very little information was available about the extent of the problem or ways to control or manage fish diseases in the wild. The U.S. Fish and Wildlife Service was the first agency to develop a standardized approach and set up a collaborative network to collect and share information. Network collaboration includes partnerships between federal and state agencies, tribes, private industry, and academia. (Credit: USFWS)
Learning more about the host-parasite relationship and understanding the effects of P. incognita on gag grouper reproduction will be beneficial for the long-term health and productivity of this important fishery. To learn more about our Fish and Wildlife Health program, visit our website.

Dexter NFHTC (Southwestern Native Aquatic Resources & Recovery Center) maintains bonytail and razorback sucker broodstock and produces larval and sub-adult fish for distribution to partners participating in fish augmentation activities of the Lower Colorado River Multi-Species Conservation Program (LCR MSCP). Annually, Dexter cultures 4,000-6,000 juvenile bonytail and 500-1000 sub-adult razorback sucker for stocking into Reach 2 and Reach 3 of the lower Colorado River. Fish transported from Dexter to the lower Colorado River remain in the hauling truck for 12 to 14 hours, subjecting the fish to various stressors such as handling, confinement, and water quality changes. Understanding the severity and duration of the physiological stress response of bonytail and razorback sucker produced by current hauling protocols is critical for effective management and successful conservation of these species. Blood samples were collected from fish at each handling stress event and at designated recovery periods. Plasma will be analyzed for cortisol, glucose, lactate, chloride ions and osmolality.

On Wednesday morning Feb. 25, 2015, Administrator for Animal and Plant Health Inspection Services Kevin Shea and Deputy Assistant Secretary of Policy and International Affairs at the Interior Lori Faeth officially launched National Invasive Species Awareness Week 2015 at an awards ceremony and information fair hosted by the Department of Agriculture. Partnerships are crucial to successfully prevent and control invasive species. The awards ceremony recognizes nine individuals and organizations for their leadership, volunteerism, lifetime achievement and outreach and education. National Invasive Species Awareness Week highlights efforts to prevent or slow the spread of invasive species—species that are both non-native to an ecosystem of concern and harmful to the environment, the economy and animal or human health. Verified RHP.

Southwestern Fish Health Unit staff collect health testing samples from non-native fishes removed from the San Juan River while monitoring for native species, like the razorback sucker depicted in this photo, is conducted. Twenty-four wild fish health surveys were conducted by Southwestern Fish Health Unit staff as part of the USFWS National Wild Fish Health Survey in FY14. Four field surveys were conducted by the staff with the remaining sites conducted by partners collecting samples for shipment to the Unit for testing. In total, 16 sites were sampled. The majority of species tested were surrogates for T&E species to provide a site health baseline prior to transferring fish into culture facilities as refugia.

The National Fisheries Friends Partnership (NFFP) brings together leading fishing, conservation, water-based recreation, industry and business groups in a unique coalition to conserve and restore the fish, wildlife and plants living in our local waters. By working in partnership with leading state and federal agencies, businesses and other non-governmental organizations, the Partnership promote volunteerism, education and opportunities for the stewardship and conservation of our fisheries and other aquatic resources.

The Idaho Fish Health Center provides the opportunity for volunteers to get laboratory and field experience and learn about fish health sampling and testing protocols. This helps the Service by getting extra assistance for projects but also gives the volunteer a better understanding of the Service, our mission, and activities performed at a USFWS fish health center.

I had to euthanize Fish this evening. He'd gotten very sick, quite possibly with Fish Tuberculosis, and wasn't responding to any medicines.
Thanks, Fish, for the good times and the laughter.
I can't believe a $3 fish made me cry.

Annual Health Condition Profiles are performed on 20 to 30 fisher per lot at Ouray National Fish Hatchery - Randlett Unit to assess aquaculture practices and ensure optimal production. This helps increase post-stocking survival of hatchery-reared fish.
