Hunting in Archerfish – an Ecological Perspective on a Remarkable Combination of Skills Stefan Schuster*

The South China Sea is a major water body containing a large and diverse fish fauna. However, many areas of the South China Sea, particularly in Malaysia and Vietnam, have been poorly studied in terms of fish taxonomy and diversity. Local fish scientists and students have frequently faced difficulty when try- ing to identify fishes in their home countries.

The Biology and Ecology of Samson Fish Seriola Hippos
The biology of Samson Fish Seriola hippos with emphasis on the sportfishery in Western Australia. By Andrew Jay Rowland This thesis is presented for the degree of Doctor of Philosophy at Murdoch University 2009 DECLARATION I declare that the information contained in this thesis is the result of my own research unless otherwise cited. ……………………………………………………. Andrew Jay Rowland 2 Abstract This thesis had two overriding aims. The first was to describe the biology of Samson Fish Seriola hippos and therefore extend the knowledge and understanding of the genus Seriola. The second was to uses these data to develop strategies to better manage the fishery and, if appropriate, develop catch-and-release protocols for the S. hippos sportfishery. Trends exhibited by marginal increment analysis in the opaque zones of sectioned S. hippos otoliths, together with an otolith of a recaptured calcein injected fish, demonstrated that these opaque zones represent annual features. Thus, as with some other members of the genus, the number of opaque zones in sectioned otoliths of S. hippos are appropriate for determining age and growth parameters of this species. Seriola hippos displayed similar growth trajectories to other members of the genus. Early growth in S. hippos is rapid with this species reaching minimum legal length for retention (MML) of 600mm TL within the second year of life. After the first 5 years of life growth rates of each sex differ, with females growing faster and reaching a larger size at age than males. Thus, by 10, 15 and 20 years of age, the predicted fork lengths (and weights) for females were 1088 (17 kg), 1221 (24 kg) and 1311 mm (30 kg), respectively, compared with 1035 (15 kg), 1124 (19 kg) and 1167 mm (21 kg), respectively for males. -

Family Toxotidae)
Rec. West. Aust. Mus., 1978,6 (4) A REVIEW OF THE ARCHERFISHES (FAMILY TOXOTIDAE) GERALD R. ALLEN* [Received 16 July 1977. Aceepted 27 September 1977. Published 31 December 1978.J ABSTRACT The six species of Toxotes which constitute the fish family Toxotidae are reviewed. This group, commonly known as archerfishes, is renowned for its ability to knock down insects from overhanging vegetation with squirts of water ejected from the mouth. The habitat consists of mangrove-lined estuaries and freshwater streams of southeast Asia, northern Australia and the islands of the western Pacific in the Indonesia-New Guinea-Philippines region. A brief diagnosis, illustrations, and tables of counts are presented for each of the following species (approximate distributions indicated in parentheses): blythi (Burma), chatareus (widespread from India eastward to northern Australia and New Guinea), jaculator (widespread from India to the New Hebrides), lorentzi (northern Australia and New Guinea), microlepis (Thailand, Sumatra, and Borneo), oligolepis (eastern Indonesia, New Guinea, and northern Australia). A generic diagnosis and key to the species are also provided. INTRODUCfION The perciform family Toxotidae is comprised of a single genus, Toxotes, which contains six species: T. blythi Boulenger, T. chatareus (Hamilton), T. jaculator (Pallas), T. lorentzi Weber, T. microlepis Gunther, and T. oligolepis Bleeker. These fishes exhibit one of nature's most remarkable feeding adaptations which has been the subject of papers by Zolotnisky (1902), Gill (1909), Smith (1936 and 1945), and AlIen (1973). When suitable prey, usually a small insect, is sighted the fish rises to the surface and ejects an aqueous 'bullet' by forcefully compressing the gill covers, thus propelling a jet of water from the mouth. -

Published by The Company of Biologists Ltd | Journal of Experimental Biology (2017) 220, 1019-1025 doi:10.1242/jeb.146936 RESEARCH ARTICLE Archerfish use their shooting technique to produce adaptive underwater jets Jana Dewenter*, Peggy Gerullis*, Alexander Hecker and Stefan Schuster‡ ABSTRACT related to the fish using their mouth as an ‘active muzzle’, i.e. a Archerfish are renowned for dislodging aerial prey using well-aimed muzzle of continuously changing cross-section that opens slowly shots of water. Recently it has been shown that these fish can shape (compared with the duration of the shot) and starts closing as the their aerial jets by adjusting the dynamics of their mouth opening and jet is just being formed. By adjusting the dynamics of the opening closing. This allows the fish to adjust their jet to target distance so that and closing phases, the fish modify lifetime and time of focus of they can forcefully hit prey over considerable distances. Here, we their water jets to adjust them to the target distance. The suggest that archerfish use the same technique to also actively relationship between the effective target range and the timing control jets under water. Fired from close range, the underwater jets precision required to adjust the opening and closing maneuvers are are powerful enough to lift up buried food particles, which the fish then remarkably similar to that in human throwing. In this celebrated ‘ ’ can pick up. We trained fish so that we could monitor their mouth uniquely human maneuver, precise temporal control of the opening and closing maneuvers during underwater shooting and release of the projectile is the key to the ability to forcefully hit compare them with those employed in aerial shooting. -

Accepted 16 February, 2011 Spitting success and accuracy of two congeneric archer fishes Toxotes chatareus and Toxotes jaculatrix were studied to determine whether spitting success and accuracy rate varied with height and/ or group size. Overall, individuals of both species exhibited greater spitting success rate when alone than in a group. Greatest spitting success was observed in T. jaculatrix (29.87%) when alone followed by T. chatareus (27.55%), while lowest spitting success (14.88%) was observed for the average of all individuals in a group of two T. chatareus and two T. jaculatrix. Based on spitting accuracy categories right side high (RH), right side low (RL) and left side high (LH) showed no significant differences among the test groups.

Toxotes Kimberleyensis, a New Species of Archerfish (Pisces: Toxotidae) from Fresh Waters of Western Australia
© Copyright Australian Museum, 2004 Records of the Australian Museum (2004) Vol. 56: 225–230. ISSN 0067-1975 Toxotes kimberleyensis, a New Species of Archerfish (Pisces: Toxotidae) from Fresh Waters of Western Australia GERALD R. ALLEN Department of Aquatic Vertebrates, Western Australian Museum, Francis Street, Perth WA 6000, Australia Conservation International, 1919 M Street, NW, Suite 600, Washington, DC 20036, United States of America [email protected] ABSTRACT. Toxotes kimberleyensis n.sp. is described from 22 specimens, 52.5–126.3 mm SL, collected from freshwater streams in the Kimberley region of northwestern Australia. It was previously identified as Toxotes oligolepis Bleeker, a poorly known species from Indonesia. However, re-examination of Bleeker’s type specimen indicates significant differences between the two species relating to the length of the dorsal spines, and lateral-line scale count. A key to the seven species of Toxotes is provided. ALLEN, GERALD R., 2004. Toxotes kimberleyensis, a new species of archerfish (Pisces: Toxotidae) from fresh waters of Western Australia.

The perciform family Toxotidae is well known for its ability the Western Australia in 2001 revealed additional significant to shoot down insects from overhanging vegetation with a differences. Therefore, it is concluded that the population jet of water squirted from the mouth. The family contains a from Western Australia is a distinct new species, which is single genus, Toxotes, which ranges from India to Vanuatu, described herein. and northern Australia to the Philippines. These fishes are common inhabitants of mangrove-lined estuaries and Materials and methods freshwater streams.
