In order to determine the biological parameters of the burrowing crayfish (Parastacus pugnax), we fenced in 900 m2 of a humid, low-lying sector in Tiuquilemu, Bío-Bío Region, Chile. Monthly samples were taken from August 2007 to August 2008, and 3,512 specimens were caught. Records were made of their carapace length (CL), total weight (TW), sex, and number of eggs (for females). The monthly size-structures showed few juveniles between 20 and 30 mm CL in nearly all months.

    Wild Species 2010 THE GENERAL STATUS OF SPECIES IN CANADA Canadian Endangered Species Conservation Council National General Status Working Group This report is a product from the collaboration of all provincial and territorial governments in Canada, and of the federal government. Canadian Endangered Species Conservation Council (CESCC). 2011. Wild Species 2010: The General Status of Species in Canada. National General Status Working Group: 302 pp. Available in French under title: Espèces sauvages 2010: La situation générale des espèces au Canada. ii Abstract Wild Species 2010 is the third report of the series after 2000 and 2005. The aim of the Wild Species series is to provide an overview on which species occur in Canada, in which provinces, territories or ocean regions they occur, and what is their status. Each species assessed in this report received a rank among the following categories: Extinct (0.2), Extirpated (0.1), At Risk (1), May Be At Risk (2), Sensitive (3), Secure (4), Undetermined (5), Not Assessed (6), Exotic (7) or Accidental (8). In the 2010 report, 11 950 species were assessed. Many taxonomic groups that were first assessed in the previous Wild Species reports were reassessed, such as vascular plants, freshwater mussels, odonates, butterflies, crayfishes, amphibians, reptiles, birds and mammals. Other taxonomic groups are assessed for the first time in the Wild Species 2010 report, namely lichens, mosses, spiders, predaceous diving beetles, ground beetles (including the reassessment of tiger beetles), lady beetles, bumblebees, black flies, horse flies, mosquitoes, and some selected macromoths. The overall results of this report show that the majority of Canada’s wild species are ranked Secure.

  • Guide to Crustacea
    46 Guide to Crustacea. Order 2.—Decapoda. (Table-cases Nos. 9-16.) The gills are arranged typically in three series—podo- branchiae, arthrobranchiae, and pleurobranchiae. Only in the aberrant genus Leucifer are the gills entirely absent. The first three pairs of thoracic limbs are more or less completely modified to act as jaws (maxillipeds), while the last five form the legs. This very extensive and varied Order includes all the larger and more familiar Crustacea, such as Crabs, Lobsters, Crayfish, FIG. 30. Penaeus caramote, from the side, about half natural size. [Table-case No. 9.] Prawns, and Shrimps. From their greater size and more general interest, it is both possible and desirable to exhibit a much larger series than in the other groups of Crustacea, and in Table-cases Nos. 9 to 16 will be found representatives of all the Tribes and of the more important families composing the Order. On the system of classification adopted here, these tribes are grouped under three Sub-orders :— Sub-order 1.—Macrura. „ 2.—Anomura. ,, 3.—Brachyura. Eucarida—Decapoda. 47 SUB-ORDER I.— MACRURA. (Table-cases Nos. 9-11.) The Macrura are generally distinguished by the large size of the abdomen, which is symmetrical and not folded under the body. The front, or rostrum, is not united with the " epistome." The sixth pair of abdominal appendages (uropods) are always present, generally broad and flattened, forming with the telson, a " tail-fan." The first Tribe of the Macrura, the PENAEIDEA, consists of prawn-like animals having the first three pairs of legs usually chelate or pincer-like, and not differing greatly in size.

  • Checklist of the Crayfish and Freshwater Shrimp (Decapoda) of Indiana
    2001. Proceedings of the Indiana Academy of Science 110:104-110 CHECKLIST OF THE CRAYFISH AND FRESHWATER SHRIMP (DECAPODA) OF INDIANA Thomas P. Simon: U.S. Fish and Wildlife Service, 620 South Walker Street, Bloomington, Indiana 47401 ABSTRACT. Crayfish and freshwater shrimp are members of the order Decapoda. All crayfish in In- diana are members of the family Cambaridae, while the freshwater shrimp belong to Palaemonidae. Two genera of freshwater shrimps, each represented by a single species, occur in Indiana. Palaemonetes ka- diakensis and Macrobrachium ohione are lowland forms. Macrobrachium ohione occurs in the Ohio River drainage, while P. kadiakensis occurs statewide in wetlands and lowland areas including inland lakes. Currently, 21 crayfish taxa, including an undescribed form of Cambarus diogenes, are found in Indiana. Another two species are considered hypothetical in occurrence. Conservation status is recommended for the Ohio shrimp Macrobrachium ohione, Indiana crayfish Orconectes indianensis, and both forms of the cave crayfish Orconectes biennis inennis and O. i. testii.

Licensed under Creative Commons Attribution-NonCommercial- ShareAlike License. Available: http://tolweb.org/Cambarellus_(Pandicambarus)_texanus. (October 2016). 1 Native Range and Status in the United States Native Range From Fetzner (2016): “East of the Lavaca River and Bay to the Brazos River drainage system, Texas.” Status in the United States From Alvarez et al. (2010): “This species was first found in a ditch near Bay City in Matagorda County, Texas. It has since been found in the Colorado River, Fort Bend County, and Waller County. It is thought that the range is bound by the Lavaca River and Bay on the west, though the northward and eastward range limits are not known (Albaugh and Black 1973).” “This species has been collected from 31 sites and is believed to be common at most sites (D. Johnson pers. comm. 2009).” 1 Means of Introductions in the United States This species has not been reported as introduced outside of its native range in the United States. Remarks From NatureServe (2015): “It is found only in Texas in a small range near the central Texas coast (Johnson and Johnson, 2008). It has a larger range than Cambarellus ninae, but does occur in an area that is experiencing urban growth; however populations appear stable and there is no evidence of decline.” 2 Biology and Ecology Taxonomic Hierarchy and Taxonomic Standing From ITIS

  • Taxonomy, Biology and Distribution of Lobsters
    Taxonomy, Biology and Distribution of Lobsters 15 Rekha Devi Chakraborty and E.V.Radhakrishnan Crustacean Fisheries Division, Central Marine Fisheries Research Institute, Kochi-682 018 Lobsters are among the most prized of fisheries resources and of significant commercial interest in many countries. Because of their high value and esteemed culinary worth, much attention has been paid to lobsters in biological, fisheries, and systematic literature. They have a great demand in the domestic market as a delicacy and is a foreign exchange earner for the country. Taxonomic status Phylum: Arthropoda Subphylum: Crustacea Class: Malacostraca Subclass: Eumalacostraca Superorder: Eucarida Order: Decapoda Suborder: Macrura Reptantia The suborder Macrura Reptantia consists of three infraorders: Astacidea (Marine lobsters and freshwater crayfishes), Palinuridea (Spiny lobsters and slipper lobsters) and Thalassinidea (mud lobsters). The infraorder Astacidea Summer School on Recent Advances in Marine Biodiversity Conservation and Management 100 Rekha Devi Chakraborty and E.V.Radhakrishnan contains three superfamilies of which only one (the Infraorder Palinuridea, Superfamily Eryonoidea, Family Nephropoidea) is considered here.
