Studies based on CalCOFI sampling in the 1950s indicated that the abun- dance of phyllosoma larvae may be sensitive to ocean- ographic conditions such as El Niño events. To further study the potential influence of environmental variabil- ity and the fishery on lobster productivity, we developed a 60-year time series of the abundance of lobster phyl- losoma from the historical CalCOFI sample collection. Phyllosoma were removed from the midsummer cruises when the early-stage larvae are most abundant in the plankton nearshore. We found that the abundance of the early-stage phyllosoma displayed considerable inter- annual variability but was significantly positively corre- Figure 1.

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. -
A New Pathogenic Virus in the Caribbean Spiny Lobster Panulirus Argus from the Florida Keys
DISEASES OF AQUATIC ORGANISMS Vol. 59: 109–118, 2004 Published May 5 Dis Aquat Org A new pathogenic virus in the Caribbean spiny lobster Panulirus argus from the Florida Keys Jeffrey D. Shields1,*, Donald C. Behringer Jr2 1Virginia Institute of Marine Science, The College of William & Mary, Gloucester Point, Virginia 23062, USA 2Department of Biological Sciences, Old Dominion University, Norfolk, Virginia 23529, USA ABSTRACT: A pathogenic virus was diagnosed from juvenile Caribbean spiny lobsters Panulirus argus from the Florida Keys. Moribund lobsters had characteristically milky hemolymph that did not clot. Altered hyalinocytes and semigranulocytes, but not granulocytes, were observed with light microscopy. Infected hemocytes had emarginated, condensed chromatin, hypertrophied nuclei and faint eosinophilic Cowdry-type-A inclusions. In some cases, infected cells were observed in soft con- nective tissues. With electron microscopy, unenveloped, nonoccluded, icosahedral virions (182 ± 9 nm SD) were diffusely spread around the inner periphery of the nuclear envelope. Virions also occurred in loose aggregates in the cytoplasm or were free in the hemolymph. Assembly of the nucleocapsid occurred entirely within the nucleus of the infected cells. Within the virogenic stroma, blunt rod-like structures or whorls of electron-dense granular material were apparently associated with viral assembly. The prevalence of overt infections, defined as lethargic animals with milky hemolymph, ranged from 6 to 8% with certain foci reaching prevalences of 37%. The disease was transmissible to uninfected lobsters using inoculations of raw hemolymph from infected animals. Inoculated animals became moribund 5 to 7 d before dying and they began dying after 30 to 80 d post-exposure. -

California Spiny Lobster Scientific Name: Panulirus Interruptus Range
Fishery-at-a-Glance: California Spiny Lobster Scientific Name: Panulirus interruptus Range: Spiny Lobster range from Monterey, California southward to at least as far as Magdalena Bay, Baja California. The physical center of the range is within Mexico, and population density and fishery productivity is highest in this area. Habitat: As juveniles (less than 3 years of age), Spiny Lobster live in coastal rubble beds, but as adults, they are found on hard bottomed or rocky-reef habitat kelp forests. Size (length and weight): Adult Spiny Lobsters average 2 pounds in weight and about 12 inches total length, with males slightly larger than females. Adults more than 5 pounds are currently considered trophy individuals, although records exist from a century ago of 26 pound, 3 foot long lobsters. Life span: Spiny Lobsters can live up to 30 to 50 years. Reproduction: Spiny Lobsters mature at about 5 years of age, or 2.5-inch carapace length. They have a complex, 2-year reproductive cycle from mating to the settlement of juvenile lobsters. Fecundity increases with size, and females produce one brood of eggs per year. Prey: Spiny Lobsters are omnivorous, and act as important keystone predators within the southern California nearshore ecosystem. Adults forage at night for algae, fish, and many marine invertebrates. Predators: Predators of juvenile Spiny Lobsters include California Sheephead, Cabezon, rockfishes, Kelp Bass, Giant Sea Bass, and octopus. Predators of adult lobsters tend to be the larger individuals such as male California Sheephead and Giant Sea Bass. Fishery: The commercial fishery accounted for approximately 312 metric tons (688,000 lb) in ex- vessel landings and $12.7 million in ex-vessel value during the 2017-2018 fishing season. -

Fitzgibbon Standard metabolic rate of spiny lobster (Sagmariasus verreauxi) pueruli determined by intermittent flow-through respirometry Q. P. Fitzgibbon Marine Research Laboratories, Tasmanian Aquaculture and Fisheries Institute, University of Tasmania, Hobart, Australia, 7001. E-mail: [email protected] Abstract An improved understanding of the metabolic physiology of larval spiny lobsters will aid the development of spiny lobster propagation. The study describes an intermittent flow-through respirometer system for larval crustaceans and discusses its benefits over typical static respirometry methods. The technique is used to determine the standard metabolic rate of the nektonic puerulus stage of the spiny lobster, Sagmariasus verreauxi. Respiration rates of intermoult pueruli (n=5) were determined every 20 min for 16 h. Pueruli metabolism was elevated for 2 h after introduction to the respirometer chamber due to the effects of transfer stress. Thereafter, metabolic rates fluctuated due to spontaneous activity. S. verreauxi pueruli mean standard metabolic rate, determined as the lowest 10% of metabolic recordings, was 0.39 ±0.03 mg h-1 gDW-1. This is substantially lower than previous recordings of Panulirus cygnus pueruli metabolism using static methodologies. The lower recorded metabolism of S. verreauxi appears due to the use of improved methods which allowed the exclusion of measurements elevated by stress or activity. The results of the current study demonstrate that the standard metabolism of pueruli is substantially reduced to previous recordings of pueruli routine metabolism. Pueruli may have reduced metabolism due to lower maintenance costs associated with lecithotrophy which may be a mechanism of preserving energy during the non-feeding stage.
