Morphological characters from a total of 164 sampled phyllosomata were ascribed to EDI_HeadC=EDI_HeadD=EDI_HeadC=EDI_HeadD/HeadC nine distinct developmental stages (stages I-IX), and described and illustrated. Although no final stage phyllosomata (stage X) were obtained, the BL in the final stage was extrapolated at ERR_HeadA=ERR_HeadB=ERR_HeadA=ERR_HeadB/HeadA 39.6 mm using a Gompertz function, expressing the relationship between phyllosoma stages ERR_HeadB=ERR_HeadC=ERR_HeadB=ERR_HeadC/HeadB and BL.

While a single performance measure may give some insight, it may not be enough to ac - curately predict outcomes. Here, we used multiple measures of performance to explore potential mech- anisms behind species range shifts. We examined the thermal pattern for multiple measures of performance, including measures of aerobic metabolism and multi- ple as pects of escape speed, using the final larval stage (puerulus) of eastern rock lobster Sagmariasus verreauxi as a model species. We found that aerobic scope and escape speed had different thermal per- Single thermal performance measures for eastern rock lob- formances and optimal temperatures.

  • 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.

  • Large Spiny Lobsters Reduce the Catchability of Small Conspecifics
    Vol. 666: 99–113, 2021 MARINE ECOLOGY PROGRESS SERIES Published May 20 https://doi.org/10.3354/meps13695 Mar Ecol Prog Ser OPEN ACCESS Size matters: large spiny lobsters reduce the catchability of small conspecifics Emma-Jade Tuffley1,2,3,*, Simon de Lestang2, Jason How2, Tim Langlois1,3 1School of Biological Sciences, The University of Western Australia, 35 Stirling Highway, Crawley, WA 6009, Australia 2Aquatic Science and Assessment, Department of Primary Industries and Regional Development, 39 Northside Drive, Hillarys, WA 6025, Australia 3The UWA Oceans Institute, Indian Ocean Marine Research Centre, Cnr. of Fairway and Service Road 4, Crawley, WA 6009, Australia ABSTRACT: Indices of lobster abundance and population demography are often derived from pot catch rate data and rely upon constant catchability. However, there is evidence in clawed lobsters, and some spiny lobsters, that catchability is affected by conspecifics present in pots, and that this effect is sex- and size-dependent. For the first time, this study investigated this effect in Panulirus cyg nus, an economically important spiny lobster species endemic to Western Australia. Three studies: (1) aquaria trials, (2) pot seeding experiments, and (3) field surveys, were used to investi- gate how the presence of large male and female conspecifics influence catchability in smaller, immature P. cygnus. Large P. cygnus generally reduced the catchability of small conspecifics; large males by 26−33% and large females by 14−27%. The effect of large females was complex and varied seasonally, dependent on the sex of the small lobster. Conspecific-related catchability should be a vital consideration when interpreting the results of pot-based surveys, especially if population demo graphy changes.

The fishery as a \^iiole inqjroved over the years reaching a record level of 0.39 miUicn tcones in 1991. Brawn landings, which accounted for about 72% of the crustacean fishery, showed a reaunkable leap since 1988 as a result of extended fishing by shrimp trawlers over time and ^ace. and the innovative fishing in the traditional sectcr. The changed fishing pattern in the mechanized as well as aitisanal sectors, and its intact en catch and ^ecies conq)osition are outlined. The average production of 0.225 millioo tcnnes of prawns realized at present is very close to the estimated catdiable potential of the 0-50 m depth zone. Stock assessments of in:;>ortant species also reveals that the coastal >shrinq> resource of India is fiilly e;q>loited at present. Some species like Metapenaeus dohsoni, Penaeus indicus and P. semisulcatus ate overfished in their respective areas of fishery. The lobster fishery, on the whole, is in a state of decline. On the north-west coast, stock assessment of the princ^al ^ecies Panulirus polyphagus has shown that to reach the MSY level trawling e£foit would have to be considerably reduced which may not be feasible as this fishing e£foit is targeted for other resources.

To improve our understanding of the status of Gulf of Mannar marine aquariumtrade in India, information on harvested species and their volume was gathered at the major IUCN Red List collection hubs (Tuticorin, Kilakarai and Mandapam) in the Gulf of Mannar region, and compared to the export Market discrepancy data. During one year, 87 species of fish (51% belonging to the family Pomacentridae) and 21 species of invertebrates were harvested for the trade. The conservation status of exploited species revealed that nearly 50% (n=43) have not been assessed for their extinction risk by the IUCN, while of the 44 species assessed, 41 were Least Concern (LC), and one each was in the Data Deficient (DD), Near Threatened (NT) and Endangered (EN) categories.
