SOME RECOLLECTIONS OF NATIVE FISH IN THE MURRAY-DARLING SYSTEM WITH SPECIAL REFERENCE TO THE TROUT COD Maccullochella macquariensis Summary & Source Material from the Draft Publication Bluenose: The Lost World of the Trout Cod W. T. TRUEMAN Electronic Version June 2007 Prepared as an Interim Report for Native Fish Australia (Victoria) Incorporated 1 Preface & Errata (Electronic Version) The electronic version of this report has been prepared in response to the requests received by Native Fish Australia (Victoria) Inc. and myself for copies. Due to the financial constraints of what is a volunteer non-profit organisation only a limited number of hard copies were prepared. Funds are currently being sought to have another run printed so that they can be more widely dispersed to government and educational institutions. In preparing the electronic version I have taken the opportunity to correct a number of errors present in the original document. Most of these were of a minor nature and do not alter the content. Several sources cited in the text were omitted in the references section. An error was made in the writing of the spreadsheet for the bar graph in Figure 2 representing potential spawning seasons at Hinnomunjie for trout cod. The graph has been corrected in this version and the relevant text amended. For these errors I apologise but ask the reader to understand that the original document was prepared at fairly short notice to meet a deadline. There are errors in syntax in sections but I have left these unchanged to preserve the document in as close to possible as original form. While I have collected additional information and photographs other than those previously presented I have for the most part elected not to include them. In the original version due to space constraints I omitted Bert McKenzie’s recollections for the middle Murray, Buffalo and Lachlan Rivers. While they have previously been published in angling publications I have included them in the relevant sections in this document to make them more readily available to the scientific community. A number of people have sought more information on David Stead’s work with the trout cod. I have included an addendum containing additional information related to Stead, the naming of the ‘trout cod’, translocation activities and references to artificial propagation trials with the species around the time of the First World War. Also included is an additional reference for the upper Mitta Mitta River. In my original introduction I alluded to the loss of detail in the printing of the photographs. Compression of the photographs to reduce file size has resulted in a further reduction in resolution. The full size versions are reasonable but enlargement results in a significant loss of detail. In some cases what were fine dashes on trout cod images become blobs, making them look like Murray cod. I have elected to present a few photographs in their original colour version. Several people have requested access to the original images and as it is the wishes of the owners that they be put to worthwhile and appropriate use I can make most of them available for scientific and government publications. Dr. Andrew Boulton has made me acutely aware of the value of the old photographs as a record not only of the fish but as a historical reference for the condition of rivers. A number of people have suggested that I should put aside the preparation of a book and for the time being concentrate on saving as many photographs and recording the oral history before they are lost to us. This suggestion has merit and I will investigate the production of a more comprehensive oral history of the fish and rivers of the Murray-Darling system. Part of such a project could entail the production of a CD preserving early images of the fish and their habitat. My current collection is somewhere between two and three hundred. If people seek more information or access to records and photographs I can be contacted through Native Fish Australia (Victoria) Inc or by either: [email protected] or [email protected] Will Trueman June 2007 2 SOME RECOLLECTIONS OF NATIVE FISH IN THE MURRAY-DARLING SYSTEM WITH SPECIAL REFERENCE TO THE TROUT COD Maccullochella macquariensis Photo: Two unknown anglers fish the Goulburn River at Prospect Hill near Molesworth for bluenose (trout cod), bream (Macquarie perch) and Murray cod, January 16 1927. Not only do photographs exist as a record of the fish once present in the rivers they also provide us with evocative images of a world lost to us. We are fortunate to gain an insight into this world through the efforts of amateur photographers such as Sadie Bryan, daughter of one of the pioneers of the Molesworth district Thomas Bryan, who captured this moment in time.

Front cover: Lithograph of Gristes macquariensis the holotype for the bluenose or trout cod published in Iconographie de regne animal de G. Cuvier, Vol 1, in 1836. The La Cochille, under the command of Louis Duperry, left France in 1822 on a voyage of discovery with the ship’s surgeon, Prosper Garnot, and assistant surgeon Rene Lesson being responsible for the collection of biological specimens. While based in Sydney from January 17 to March 25 1824 an expedition to the Bathurst area occurred during which the holotypes for the trout cod and Macquarie perch (Macquaria australasica) were collected it is believed from the Macquarie River. After his return to France Lesson in 1825 named the species Gryptes brisbanii and no formal description survives though a later document implies its existence. In 1829 the same specimen was named Grystes macquariensis and described by the French naturalists Georges Cuvier and Achille Valenciennes.

Becker perished shortly afterwards on the Bourke and Wills expedition. The fish was reported to have been three feet four and a half inches in length. This illustration was subsequently used in the preparation of Plate 85 in Frederick McCoy’s Prodromus of the Natural History of Victoria, 1884. Berra & Weatherly (1972) considered the illustration to be of a trout cod though others have doubted it, mainly because trout cod have not been previously reported to grow to the size of the specimen illustrated. Certain identification of the fish as a trout cod is not possible with the mouth open. Sketchings and notes by Becker lend weight to the fish being a trout cod. The lithograph published in McCoy’s work has a distinctly grey-green background colour. In this lithograph held by Museum Victoria the fish is distinctly blue in colour.

The figure was ultimately used to prepare Plate 85 of Frederick McCoy’s Prodromous of the Natural History of Victoria, published posthumously in 1884. The sketch may depict a fish known to anglers as a ‘bluenose’, ‘rock cod’ or ‘trout cod’. If so the drawing provides the earliest reference to what was to become a trademark feature of an enigmatic fish.

Above all the many anglers who shared their memories are the principal contributors and provide all of us an insight to the world they once knew. They are acknowledged throughout but a number stand out for special mention. Roy Grant of Burrowye not only shared his stories but his beautiful photographs as did Tom Jarvis of Tintaldra and Len Lebner of Corryong. For the Goulburn River Frank Moore and Russell Stillman recalled their stories as well as providing photographs of historic significance. At Seymour Jim Hanley rounded up for me the senior anglers of the district and their photographs. Similarly Lance White of the Whorally Angling Club and Ray Hopkins of the Yea Angling Club organized interviews with senior anglers in their districts. Two people who are non-anglers also made major photographic contributions. Muriel Perry of Molesworth shared her priceless photos of catches of cod from the Goulburn which were a great source of satisfaction in that they verified the stories of the late Bert McKenzie. Margaret Pendergast of Benambra provided a photograph of a trout cod which, while not visually the best in my collection, is one of the most significant. Members of many local historical societies provided assistance in the research though sadly in most cases very little material exists in their files. Heather Rendell of the Echuca Historical Society has been tireless in her endeavors on my behalf while Madeleine Forgie of the Cowra Historical Society provided important contacts for me in the upper Lachlan. Max Dyer and Coral Kracke have provided key information on the Omeo district as well as background information which my research has benefited from. Julie Whateley of the Swan Hill Historical society is still hard at work for me searching and copying old photographs.
