Estimating growth of the Spiny Lobsters Panulirus cygnus, P.argus and P. ornatus

Abstract

Growth in three species of spiny lobster-Panulirus cygnus in Western Australia, P. argus in Cuba, and P. ornatus in Torres Strait, Australia-was modelled by using nonlinear random-coefficient models. Approximate confidence intervals about the mean growth curve for carapace length, to include 95% of the population at any age, have been estimated for these models. For both P. ornatus and P. cygnus, similar estimates of growth rate were obtained from both laboratory and field studies. Growth of the two tropical species, P. ornatus and P. argus, was much faster than that of the temperate species P. cygnus. All three species showed high variability in the growth rates of individuals. Microtagging of first-moult post-puerulus juveniles of P. cygnus with 1 mm long × 0.25 mm stainless-steel tags provides the first published field data on the growth of spiny lobsters from the beginning of the benthic period. These data suggest that tagging or handling can decrease the growth rates of spiny lobsters.

Life History of the Red Spiny Lobster, Panulirus penicillatus (Decapoda: Palinuridae), in the Galápagos Marine Reserve, Ecuador1

“…This is consistent with other populations of the same species (e.g., Juinio 1987, Plaut andFishelson 1991) and in other lobster species (Morgan 1980, Phillips et al 1992. The lower K values estimated for P. penicillatus in the Red Sea (K ¼ 0.0497 and 0.1066 for males and females, respectively) were explained by Plaut and Fishelson (1991) to be the result of the extreme northern location within the distribution range for the species.…”

Use of neurolipofuscin to determine age structure and growth rates of Caribbean spiny lobsterPanulirus argusin Florida, United States

“…our determination of Cl for lobsters from the dry Tortugas was consistent with the lower estimates of Cl from the region, but our estimates for Cl at the Florida Keys were considerably lower. our estimates of k were substantially higher than most estimates (FAo 1998), although our estimates of growth were within the upper range for P. argus in Cuba (Phillips et al 1992). The high Ses for k for Florida Keys lobsters were likely caused by the high variability in size for age-1 and age-2 lobsters.…”

“…The same microwire-tag study also reported some individuals growing to 55 mm Cl in less than 1 year and some individuals that were recaptured before 1 year had projected growth rates to 75 mm Cl in 1 year. Phillips et al (1992) also reported individual P. argus with projected growth rates of over 75 mm Cl at 1 year. Growth rates estimated from recaptured lobsters tagged with the more invasive spaghetti tag (hallprint T M) generally included many lobsters that did not moult (warner et al 1977;davis 1981;lyons et al 1981;Forcucci et al 1994;Muller et al 1997).…”

“…Hasil penelitian oleh Fatah (2004) di Kabupaten Kebumen dan sekitarnya menunjukkan bahwa nilai K sebesar 0,6 per tahun dan panjang karapas asimtotiknya (L  ) sebesar 107 mm. diperairan Great Barrier Reef Australia sebesar K sebesar 0,27 per tahun dengan panjang karapas infinitif (CL  ) sebesar 144,7 mmCL (Frisch, 2007), kisaran panjang karapas asimtotik (L  ) sekitar 118-164 mm; K, 0,27-0,54 tahun-1 (Phillips et al, 1992;Pitcher, 1993;Skewes et al, 1997), sedangkan lobster mutiara (Panulirus ornatus) di Torres Strait Australia nilai K sebesar 0,157 per tahun dengan panjang karapas infinitif (CL  ) sebesar 150,7 mmCL (Philips et al, 1992).…”
