Le Bris), http://umaine.edu/wahlelab/current-projects/american-lobster-settlement-index/ Several months now into the COVID-19 pandemic, we can only look back to the 2019 fishing year with some nostalgia. In calendar year 2019, Canadian lobster landings continued to boast near all-time highs. And while US landings have slipped a bit from their own historic highs, much of those losses have been offset by continued high value. That is, until now. All that changed almost overnight with the onset of the pandemic, as demand for lobster plummeted with shuttered restaurants and overseas commerce, dragging down the price of lobster, much to the distress of fishing communities up and down the coast. As we enter the 2020 summer fishing season, the lobster industry grapples to find a new normal as it accommodates health protocols, readjusts markets and scales back revenue expectations. In kind, state and federal marine resource monitoring programs are equally rethinking sampling programs under shrinking tax revenues and new safety standards. Last year’s Update examined how well ALSI predicted trends in the fishery from Fundy to Rhode Island. -
Metanephrops Challengeri)
Population genetics of New Zealand Scampi (Metanephrops challengeri) Alexander Verry A thesis submitted to Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity. Victoria University of Wellington 2017 Page | I Abstract A fundamental goal of fisheries management is sustainable harvesting and the preservation of properly functioning populations. Therefore, an important aspect of management is the identification of demographically independent populations (stocks), which is achieved by estimating the movement of individuals between areas. A range of methods have been developed to determine the level of connectivity among populations; some measure this directly (e.g. mark- recapture) while others use indirect measures (e.g. population genetics). Each species presents a different set of challenges for methods that estimate levels of connectivity. Metanephrops challengeri is a species of nephropid lobster that supports a commercial fishery and inhabits the continental shelf and slope of New Zealand. Very little research on population structure has been reported for this species and it presents a unique set of challenges compared to finfish species. M. challengeri have a short pelagic larval duration lasting up to five days which limits the dispersal potential of larvae, potentially leading to low levels of connectivity among populations. The aim of this study was to examine the genetic population structure of the New Zealand M. challengeri fishery. DNA was extracted from M. challengeri samples collected from the eastern coast of the North Island (from the Bay of Plenty to the Wairarapa), the Chatham Rise, and near the Auckland Islands. DNA from the mitochondrial CO1 gene and nuclear ITS-1 region was amplified and sequenced. -

Factors Affecting Growth of the Spiny Lobsters Panulirus Gracilis and Panulirus Inflatus (Decapoda: Palinuridae) in Guerrero, México

Abstract: The effects of sex, injuries, season and site on the growth of the spiny lobsters Panulirus gracilis, and P. inflatus, were studied through mark-recapture techniques in two sites with different ecological characteristics on the coast of Guerrero, México. Panulirus gracilis occurred in both sites, whereas P. inflatus occurred only in one site. All recaptured individuals were adults. Both species had similar intermolt periods, but P. gracilis had significantly higher growth rates (mm carapace length week-1) than P. inflatus as a result of a larger molt incre- ment. Growth rates of males were higher than those of females in both species owing to larger molt increments and shorter intermolt periods in males. Injuries had no effect on growth rates in either species. Individuals of P. gracilis grew faster in site 1 than in site 2. Therefore, the effect of season on growth of P. gracilis was analyzed separately in each site. In site 2, growth rates of P. gracilis were similar in summer and in winter, whereas in site 1 both species had higher growth rates in winter than in summer. -

San Diego, CA 92123 ph: (858) 534-7284 Bodega Bay, CA 94923-0247 [email protected] ABSTRACT The California spiny lobster (Panulirus interruptus) population is the basis for a valuable commercial and recreational fishery off southern California, yet little is known about its population dynamics. 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.

This paper examines past knowledge of shell disease, supplements this with the new knowledge generated through a special New Eng- land Lobster Shell Disease Initiative completed in 2011, and suggests how epidemiological tools can be used to elucidate the interactions between fisheries management and disease.

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Condrey KEY WORDS: Gulf of Mexico, Ship Shoal, Trinity Shoal, Tiger Shoal, Louisiana, sand mining, blue crab, white shrimp, brown shrimp, spotted seatrout, condition factor, fecundity, spawning grounds, coastal restoration BACKGROUND: The Minerals Management Service (MMS) is addressing the recent demand for U.S. continental shelf sand resources for coastal erosion management, a critical challenge to Louisiana’s ecosystems and economies. Louisiana considers barrier island restoration as a promising way to combat wetland loss, with sand mined from Ship Shoal as the most feasible sediment source. Additional sand resources on Trinity and Tiger Shoals are also being considered. Since this area supports major demersal fisheries on white and brown shrimp (Litopenaeus setiferus and Farfantepenaeus aztecus), the present study was conducted as part of a larger effort to understand the sand-mining ecology of the Ship/Trinity/Tiger Shoal Complex (STTSC). -
Behavioural Effects of Hypersaline Exposure on the Lobster Homarus Gammarus (L) and the Crab Cancer Pagurus (L)

E-mail address: [email protected] (K. Smyth). Suggested citation: Smyth, K., Mazik, K., and Elliott, M., 2014. Behavioural effects of hypersaline exposure on the lobster Homarus gammarus (L) and the crab Cancer pagurus (L). Journal of Experimental Marine Biology and Ecology 457: 208- 214 Abstract There is scarce existing information in the literature regarding the responses of any marine species, especially commercially valuable decapod crustaceans, to hypersalinity. Hypersaline discharges due to solute mining and desalination are increasing in temperate areas, hence the behavioural responses of the edible brown crab, Cancer pagurus, and the European lobster, Homarus gammarus, were studied in relation to a marine discharge of highly saline brine using a series of preference tests. Both species had a significant behavioural response to highly saline brine, being able to detect and avoid areas of hypersalinity once their particular threshold salinity was reached (salinity 50 for C. pagurus and salinity 45 for H. gammarus). The presence of shelters had no effect on this response and both species avoided hypersaline areas, even when shelters were provided there. If the salinity of commercial effluent into the marine environment exceeds the behavioural thresholds found here, it is likely that adults of these species will relocate to areas of more favourable salinity.
