“…Lobsters exposed to control conditions and concentrations <0.82 µg/L displayed specific growth rate and moult increment within the expected range (Cobb and Castro 2006;Daoud et al 2014). Exposure to 0.82 µg/L chlorpyrifos significantly affected growth by decreasing specific growth rate and moult increment as well as increasing intermoult period when compared to control lobsters, decreasing the amount of growth while increasing the time to reach moult.…”

The organophosphate pesticide chlorpyrifos has been introduced to the marine environment via adsorption to agricultural soil runoff or as spray drift. Chlorpyrifos affects the survival of some larval decapod crustaceans, but no data exist on the impacts to the American lobster, Homarus americanus. The purpose of the present study was to assess the levels at which chlorpyrifos affects the survival of postlarval H. americanus. Using acute saltwater exposures, the 24‐ and 48‐h median lethal concentrations were established for stage IV H. americanus (1.56 and 1.33 µg/L, respectively). Movement, acetylcholinesterase activity, intermoult period, specific growth rate, and moult increment were measured during exposure to sublethal concentrations. Movement patterns were assessed to establish a 48‐h median inhibition concentration for cessation of normal movement (0.66 µg/L). Acetylcholinesterase activity was found to be inhibited immediately post‐exposure to 0.50, 0.57, and 0.82 µg/L chlorpyrifos but could be recovered within a period (9–15 d) in clean seawater. Sublethal growth effects of increased intermoult period, decreased specific growth rate, and decreased moult increment were observed during exposure to an environmentally relevant concentration (0.82 µg/L). The present study suggests that H. americanus stage IV larvae were marginally less sensitive to chlorpyrifos compared with other decapods and that acute lethality of H. americanus postlarvae is not likely to occur with chlorpyrifos concentrations previously reported from aquatic environments.

“…In our review of the literature we could only find one other spiny lobster fishery regulated with a legal maximum length, that being the western Australian fishery for Panulirus cygnus (Phillips & Melville-Smith 2006). Legal maximum lengths are regulated for several hommarus fisheries (Cobb & Castro 2006). Some lobster fisheries are managed with other (or as well as in the case of P. cygnus) management measures to protect spawning stock including seasonal closures; for example, the Australian fisheries for P. cygnus (Brown & Phillips 1994) and J. edwardsii (Linnane et al 2010), the Bahama fishery for P. argus (Phillips & Melville-Smith 2006), the fishery for Homarus americanus in Nova Scotia (Miller & Breen 2010) and protection of ovigerous females (Jasus edwardsii : Miller & Breen 2010;Punt et al 2012;P.…”

“…Legal minimum lengths have been set in lobster fisheries at around the size at which 50% of females are first mature so that most animals have a chance to spawn at least once before being susceptible to capture (e.g. Booth 2006;Cobb & Castro 2006;Groeneveld et al 2006;Phillips & Melville-Smith 2006). In contrast, the legal minimum length for S. verreauxi was introduced in 1902 for marketing reasons at a length which was considered to be a 'plate-sized' lobster.…”

Catch per unit effort in the fishery for eastern rock lobsters peaked in 1971Á72 and then declined until 1992Á93. In response to this pattern, a management package consisting of individual catch quotas, restricted entry and a legal maximum length was imposed upon the fishery. The effectiveness of these management measures to rebuild the eastern rock lobster population has been monitored annually through data collected from surveys of puerulus larvae abundance, fishery independent surveys, a compulsory logbook, observer surveys and biological studies. The total allowable commercial catch (TACC) is set annually by the TAC Committee after considering submissions from the public and industry and an annual report for the lobster fishery. The annual report prepared by government consists of an appraisal of the performance of the fishery against the objectives of the share management plan and goals of the fishery management strategy for the rock lobster fishery and includes a formal stock assessment. The trigger points behind the objectives and goals relating to the status of the stock have not been activated in the 2010Á11 year. Total biomass and exploitable biomass have increased, spawner biomass has increased to now be above 25% of the pre-exploited biomass and the relative abundance of recruits (puerulus larvae) to the population is increasing. The stock is considered to be rebuilding and the resource now supports a viable fishery with an increasing share price.

“…The American lobster is widely distributed over the continental shelf of the western North Atlantic ocean, ranging from Labrador to North Carolina (ASFMC 2012; Cobb and Castro 2006). They are considered one of the most valuable commercial fisheries along the U.S. Atlantic coast, particularly in New England waters (ASFMC 2012; Steneck and Wilson 2001).…”

Effects of Electromagnetic Fields on Fish and Invertebrates Task 2.1.3: Effects on Aquatic Organisms Fiscal Year 2012 Progress Report Environmental Effects of Marine and Hydrokinetic Energy

Energy generated by the world's oceans and rivers offers the potential to make substantial contributions to the domestic and global renewable energy supply. However, the marine and hydrokinetic (MHK) energy industry faces challenges related to siting, permitting, construction, and operation of pilotand commercial-scale facilities. One of the challenges is to understand the potential effects to marine organisms from electromagnetic fields, which are produced as a by-product of transmitting power from offshore to onshore locations through underwater transmission cables. This report documents the progress of the third year of research (fiscal year 2012) to investigate environmental issues associated with marine and hydrokinetic energy (MHK) generation. This work was conducted by Pacific Northwest National Laboratory (PNNL) for the U.S. Department of Energy's (DOE's) Office of Energy Efficiency and Renewable Energy (EERE) Wind and Water Technologies Office. The report addresses the effects of electromagnetic fields (EMFs) on selected marine species where significant knowledge gaps exist. The species studied this fiscal year included one fish and two crustacean species: the Atlantic halibut (Hippoglossus hippoglossus), Dungeness crab (Metacarcinus magister), and American lobster (Homarus americanus).

We thank Dr. Ralph Elston with AquaTechnics Inc. for providing the health and pathology report of the American lobsters prior to experimental work, and Dr. Carl Wilson with the Maine Department of Natural Resources for providing advice and support in securing a source of live lobsters for experimental purposes. We also thank PNNL staff for their review and comments (Jeff Ward, Dr. Charles Brandt, and Simon Geerlofs), editorial support (Susan Ennor) and technical staff who participated in these studies, including
