A: Because he was a little shellfish! Synopsis The overall aim of this project was to consider several freshwater invertebrates that are restricted both geographically and climatically to determine their population genetic structure, population distribution and population viability. The study was set in a framework of genetic analysis as genetics can be used to answer a whole suite of conservation focused questions. Specifically, the study concentrated on the population dynamics of three freshwater crayfish from the genus Euastacus: E. hystricosus, E. urospinosus and E. robertsi. Also, in this study I explored the role of two commensal flatworms as proxy species, to aid in disentangling the population structure of their crayfish hosts. These flatworms were Temnosewellia batiola, which is specific to E. hystricosus and Temnosewellia albata, which is specific to E.

The study is based on the analysis of 12 samplings, from October 2001 to May 2002, in which 668 organisms were collected. The size range recorded was 2.1 to 41.5 mm total length. The males had smaller sizes than females, and were classified as juveniles, form I and form II. The constant presence of form I males and ovigerous females, together with the presence of small sized individuals in most of the samples suggest that there is a continuous reproduction during the study period. The growth estimates, based on a modal progression analysis of length-frequency data, resulted in a mean daily growth rate of 0.084 mm, or a mean monthly rate of 2.535 mm. The sizes at first reproduction were 24 mm total length for females and 21 mm for males, attained between 248 and 284 days of age. The mortality estimate, computed as Z (instantaneous mortality rate), shows that there is a high mortality during the first two months of life and that only 4% of the population is reaching reproductive sizes. No relation was found between number of C.

(;ommonwealth Scientific and Industrial l~csearch Organization - Divhdon of Entomology, Canberra, A.C.T. (Figures 1-13.) Freshwater crayfish occur in almost every body of fresh water from artificial damfl and natural billabongs (I>tanding water) to headwater creeks and large rivers (flowing water). Generally the species are of considerable size and therefore easily collected, but even so many of the larger forms are unknown scientifically. This paper deals with all the species that have been collected from Queensland. It also includes a few species from New South Wales and other States. No doubt additional species will be found and some of the mOre variable series, at present included under the one specific namc, will be further subdivided. From Queensland nine species are described as new, making a total of seventeen species (of three genera) recorded from that State. The type localities of all but two of these species are in Queensland but some are not restricted to the State. Clark's 1936 and subsequent papers have been used as the basis for further taxonomic studies of the Australian freshwater crayfish.

    © Copyright Australian Museum, 2005 Records of the Australian Museum (2005) Vol. 57: 361–374. ISSN 0067-1975 New Crayfishes (Decapoda: Parastacidae: Euastacus) from Northeastern New South Wales, Australia JASON COUGHRAN School of Environmental Science and Management, Southern Cross University, Lismore NSW 2480, Australia [email protected] ABSTRACT. Routine astacological surveys in northeastern New South Wales have revealed four new species of crayfish. Three species are allied to the “setosus complex”, a group of small and poorly spinose Euastacus previously recorded only from Queensland: E. girurmulayn n.sp. from the Nightcap Range, E. guruhgi n.sp. from the Tweed volcanic plug and E. jagabar n.sp. from the Border Ranges. These three species are differentiated chiefly on features of the sternal keel, spination and antennal squame. Euastacus dalagarbe n.sp., recorded from the Border Ranges, has affinities with a growing group of crayfish displaying morphological traits intermediary between the setosus complex and more characteristically spinose Euastacus. It differs markedly in spination of the chelae, and in the nature of the lateral processes of the pereiopods. All of these taxa occur in association with the much larger and more spinose E. sulcatus. An unusual crayfish specimen of uncertain status is also discussed. COUGHRAN, JASON, 2005. New crayfishes (Decapoda: Parastacidae: Euastacus) from northeastern New South Wales, Australia. Records of the Australian Museum 57(3): 361–374. Recent taxonomic revision of the genus Euastacus (Morgan, distinct from the setosus complex, being medium to large in 1986, 1988, 1997) resulted in both the description of several size and of moderate to strong spination. Recently, increased new species and synonymies of others, including the sampling in the region extended the distribution of E.

Crayfish surveys were undertaken at 245 regional sites between 2001 and 2005, and the species was recorded at 27 sites in the Clarence, Richmond and Tweed River drainages of New South Wales, including the only three historic sites of record in the state, Brindle Creek, Mount Warning and Richmond Range. The species was restricted to highland, forested sites (220–890 m above sea level), primarily in national park and state forest reserves. Adult crayfish disappear from the observable population during the cooler months, re-emerging in October when the reproductive season commences. Females mature at approximately 50mm OCL, and all mature females engage in breeding during a mass spawning season in spring, carrying 45–600 eggs. Eggs take six to seven weeks to develop, and the hatched juveniles remain within the clutch for a further 2.5 weeks. This reproductive cycle is relatively short, and represents a more protracted and later breeding season than has been inferred for the species in Queensland. A combination of infrequent moulting and small moult increments indicated an exceptionally slow growth rate; large animals could feasibly be 40–50 years old.
