PRIMITIVE FISHES
Here’s the schedule for the Ancient Fishes Symposium at the 2016 American Fisheries Society Annual Meeting in Kansas City! We will provide updates accordingly. For those of you not attending, you can follow the symposium on Twitter with the hashtag #AncientSportFish!We’ll follow up with recap posts in the future; if you have any questions, email solomonrdavid@gmail.com.INTRODUCTION
Welcome to PrimitiveFishes.com! This site is dedicated to the ecology, natural history, and conservation of "primitive" bony fishes: the lungfishes, bichirs, sturgeons, paddlefishes, gars, and bowfin. Thanks for visiting! ~Solomon R. David, Ph.D. Introduction to Primitive Fishes Generally speaking, non-teleost fishes that are the living representatives of ancient lineages are considered to be OTHER PRIMITIVE FISHES African bonytongue (Heterotis niloticus) Less-derived teleost fishes are also sometimes considered "primitive", such as members of Osteoglossiformes (bony-tongues), which include old-world knife fishes (Notopteridae), arowanas (Osteoglossidae), arapaima and African bonytongue (Arapaimidae), African butterflyfish (Pantodontidae), and aba-aba (Gymnarchidae). REFERENCES | PRIMITIVE FISHES Primary and current references on various aspects of primitive fishes will be listed here. If you have a reference you think should be listed, please email me at solomonrdavid@gmail.com. References should be listed in the format of the American Fisheries Society to maintain consistency. Publications (updated 11.2.2012) 2012 Clement, A.M. 2012. POLYPTERUS | PRIMITIVE FISHES The family Polypteridae (larger group Cladistia, Polypteriformes) consists of the most primitive Actinopterygians (ray-finned fishes), the bichirs and ropefish. All members of Polypteridae are found in Africa. Members of this group are characterized by numerous dorsal finlets (number varies with species), lobe-supported pectoral fins, and ganoid scales (similar in appearance to those of the LUNGFISHES | PRIMITIVE FISHES Lungfishes (Sarcopterygii, Dipnoi) are considered to be among the most primitive living fishes. More specifically, they are the oldest extant lineage of jawed, bony fishes. There are three families and six extant species of these ancient fishes. Four species are found in the family Protopteridae (African lungfishes) and one species each in Ceratodontidae (Australian lungfish) BOWFIN | PRIMITIVE FISHES The bowfin Amia calva is the only living member of the family Amiidae, and part of the larger group Holostei which includes the gars. Bowfin are easily identified by their elongate dorsal fin, which undulates when swimming. Bowfin also possess nostril tubercles and a gular plate. Juveniles have a yellow-ringed ocellus located in the upper GARS | PRIMITIVE FISHES Gars (Ginglymodi, Lepisosteiformes) belong to the family Lepisosteidae and are among the most primitive of predatory fishes. Together with their closest relatives the bowfins, they make the group Holostei.

The tropical gar is one of two tropical members of the family Lepisosteidae (gars), and ranges from Mexico to Costa Rica. These fish are aquacultured in much of their range both as food fish and to restock dwindling wild populations. You can see these fish on exhibit in the “Islands & Lakes” gallery of Shedd Aquarium as well as atthe Belle

ALLIGATOR GAR NEED YOUR HELP! Posted on January 27, 2019by Solomon R David

Please help support science-based conservation of Alligator Gar populations in Texas by signing our petition!
The implications of these proposed regulations are important to conservation of all gar species, as well as other fishes; YOUR SIGNATURE IS VALUABLE EVEN IF YOU’RE NOT FROM TEXAS! PETITION: Stand with Texas to Protect Alligator Gar from OverharvestPETITION DETAILS:
The Texas Parks and Wildlife Department (TPWD) is concerned about potential overharvest of the Alligator Gar (_Atractosteus spatula_). Recent scientific research suggests that the species’ stronghold could be threatened if stronger harvest regulations are not established to protect AlligatorGar populations.
TPWD has proposed new rule changes that affect the size and method of how Alligator Gar can be harvested. These rule changes, if put into law, would include a maximum size limit of four feet in length for Alligator Gar from the Trinity River between the I-30 Bridge in Dallas County to the I-10 Bridge in Chambers County. Additionally, bowfishing would be limited to only daylight hours statewide. Current Texas law allows the harvest of one Alligator Gar per day per person. Based on scientific data, feedback from a recent survey conducted by TPWD, and the growing popularity of the bowfishing sport,the Texas trophy fishery for Alligator Gar may be at risk. Please sign the petition and show your support to help protect Texas Alligator Gar for future generations; we also appreciate your sharing this petition to garner additional support!Advertisements

Fish are the most diverse group of vertebrates on earth – almost 28,000 species — more than half of all living vertebrate species. So, perhaps, it isn’t surprising that fish have the record for both the shortest and longest vertebrate lifespan. While a pet Goldfish (_Carassius auratus_) has a typical lifespan of 6-7 years, they have been reported to live as long as 30 years (Lorenzoni et al. 2007).
Still your average aquarium fish cannot compare to these short-lived and long-lived species!SHORTEST-LIVED
The record for shortest recorded vertebrate lifespan goes to the Coral Reef Pygmy Goby (_Eviota sigillata_). This little Indo-West Pacific reef fish, less than an inch long, has a lifetime which isn’t much longer. It spends three weeks as larvae, quickly metamorphoses within one to two weeks, and settles…View original post

CONSERVATION OF ANCIENT FISHES, AND THAT “ALLIGATOR GAR VS. ASIAN CARP” QUESTION… Posted on August 9, 2016by Solomon R David
Reply
Alligator Gars (_Atractosteus spatula_) have been getting a lot of attention in the media recently, from headlines that they are “a weapon against Asian Carp”
to the hunt for a single gator gar in small-town New York to “they’re not weapons against Asian Carp.”
We had the opportunity to provide insight and additional background information on the Illinois Alligator Gar Reintroduction,
conservation of ancient fishes, and
what current science suggests regarding Asian Carp control. Please read and share , more to come!SHARE THIS:

ANGLING FOR DINOSAURS! Posted on January 25, 2016by
Solomon R David

We are planning a new symposium focusing on the ecology, conservation, and management of Holostean Fishes (Gars and Bowfin) for the 2016 American Fisheries Society conference in Kansas City, Missouri! Please share with those who may be interested, and see contact info below if you have questions/comments. More information coming soon! ANGLING FOR DINOSAURS: STATUS AND FUTURE STUDY OF THE ECOLOGY, CONSERVATION AND MANAGEMENT OF ANCIENT FISHES A special symposium is planned for the 146th annual meeting of the American Fisheries Society in Kansas City, Missouri in August 2016. This symposium will focus on the biology, ecology, life history, conservation and management of Holostean Fishes (Bowfin and gar species). As anglers’ perceptions of these ancient fishes begin to transform from “rough fish” to “sport fish,” the need for a better understanding of the ecology and conservation status of these species is fundamental to effective management. We intend to highlight past and current research by including presentations related to: * Biology/ecology/life history * Age and growth evaluations * Population genetics & evolutionary perspectives * Sampling methodologies * Management evaluations* Hybridization
* Human dimensions
If you manage or are conducting research related to Holostean fisheries, please consider participating in this special symposium. The organizers are planning some type of proceedings or special journal issue where presenters can publish their work if they wish, but the final decision will be based on input from participants. If you have information you’d like to share that would advance our understanding of Ancient Fishes, please contact the organizers formore information.
The organizers are also seeking potential sponsors for this event. If you or your organization is interested in sponsoring the symposium, please contact the organizers.Organizers:

GAR WARS! CONSERVE NATIVE BIODIVERSITY! JOIN THE DISCUSSION 7/8/2015NOON EST
Posted on July 4, 2015by Solomon R David
Reply
There’s been a lot of recent discussion reGARding bowfin, gars, and other “rough fish” in the context of bowfishing (often wasteful harvest of native species),
management (regulated harvest), and conservation. All three of these activities need not exist in conflict with each other (except wasteful harvest). We are raising awareness as to the value of these species in some cases, but there’s still much work to be done! With conservation and managed harvest (including bowfishing) in mind, we are pleased to bring you the “GAR WARS” Twitter chat via The Nature Conservancy! We invite ALL interested individuals, groups, etc to join the discussion on July 8, at noon EST. http://www.nature.org/ourinitiatives/regions/northamerica/areas/greatlakes/explore/talknature-twitter-chat.xml Please share with others who may be interested, and we hope to further raise awareness as to the conservation value of these oft-maligned ancient native species!SHARE THIS:

PERPETUATING THE MYTH OF “TRASH FISH” AND WASTEFUL KILLING OFNATIVE SPECIES
Posted on May 21, 2015by Solomon R David
1
Photo Credit: Matt Nager/Outdoor Life Magazine We will comment further soon, but in short, Outdoor Life Magazine has posted a recent article on a bowfishing tournament.
The story exemplifies a continuing systemic problem of wasteful killing and eradication of native species such as gar, buffalo, and bowfin. Using bowfishing to remove invasive carps is one thing, or if bowfishers are eating the native fishes they shoot (there’s no catch-and-release in bowfishing), more power to them. But wasteful killing of native species, often top predators and important components of native food webs and ecosystems, is unnecessary and unacceptable. Take a look at all the photos; if these were piles of dead bass, trout, walleye or muskie, there would be an outrage. Not the same for gar, bowfin, and suckers. It’s unfortunately legal (and often encouraged) in many areas, as there is money to be made. If you’d like to see a change, please contact your state’s Department of Natural Resources, Fish & Wildlife Office, and/or other conservation agencies. More to come.SHARE THIS:

WARNING: GRAPHIC (but educational) – A throwback to our research on Spotted Gar (_Lepisosteus oculatus_) ecology in 2011, here’s an impromptu video on sex determination of the species. In order to better understand species’ population and life history characteristics (and inform conservation and management), we need to know its size and age structure, as well as variation of that structure between males and females. In general, the sex of gars cannot be determined externally, therefore a population sample is dissected for internal examination. We used other structures of the fish (otoliths, rays, bones, etc) for additional analyses.references:
