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.

  • Lobster (Homarus Omericanus) Abundance in the Canadian
    NOT TO BE CITED WITHOUT PRIOR REFERENCE TO THE AUTHOR(S) Northwest Atlantic Fisheries Organization NAFO SCR Doc. 89/82 Serial No. NI666.... SCIENTIFIC COUNCIL MEETING — SEPTEMBER 1989 Lobster (Homarus omericanus) Abundance in the Canadian Maritimes Over the Last 30 Years, an Example of Extremes by D. S. Pezzack Benthic Fisheries and Aquaculture Division, Dept. of Fisheries and Oceans P. 0. Box 550, Halifax, Nova Scotia, Canada B3J 257 Abstract Lobster is one of the most important fisheries in inshore fishing communities of eastern Canada. During the last 30 years the fishery has experienced its lowest and highest landings in the 100 years of recorded landings. Landings in many parts of the coast reached record or near record lows in the late 1960's and early 1970's, then rose to high levels not experienced since 1900. Total Canadian lobster landings doubled between 1977 and 1986 and in some areas landings increased tenfold. The increase in landings during the last 10 years appears to be the result of increased recruitment. The recent increase in lobster landings have occurred in different stocks and management regimes, suggesting a wide spread environmental factor(s) as the primary cause. z Introduction Lobster is one of the most important fisheries in inshore fishing communities of eastern Canada (Fig.1), • representing 28% of the total landed value of Atlantic Canada fish in 1985.

  • Lobster Homarus Americanus
    MARINE ECOLOGY PROGRESS SERIES Vol. 85: 83-91.1992 Published August 27 Mar. Ecol. Prog. Ser. I l Natural diet and feeding habits of the postlarval lobster Homarus americanus Marie Antonette R. Juinio*,J. Stanley Cobb Department of Zoology, University of Rhode Island. Kingston, Rhode Island 02881, USA ABSTRACT: Postlarval Homarus arnericanus were collected from Block Island Sound, Rhode Island, USA, during 5 die1 neuston sampling periods in summer 1988 and 1989. The foregut contents of the postlarvae were determined and compared with the relative abundances of potential prey groups in the plankton. Nine taxonomic prey groups were identified in the gut contents (N = 802). The composi- tion of the prey groups and their relative frequencies of occurrence in the guts did not differ with time of day or sampling period. The frequent occurrence of copepods, decapod larvae, fish eggs and insect parts indicates a predominantly carnivorous feeding habit. Furthermore, the disproportionate fre- quency of occurrence of large copepod species and decapod larvae in the guts relative to their densities in the plankton suggests a preference for larger sized prey. Contrary to expectations, the mean gut fullness and condition of gut contents of individuals at different molt stages were not significantly different. Likewise, there was no significant difference in the incidence of guts with newly ingested prey between postlarvae in the premolt stages and those in the post and intermolt stages. Completely empty guts were rare. In addition, the variability in gut fullness and the condition of gut contents among individuals was high during all sampling periods. These indicate that postlarvae in the field forage successfully throughout the day.

We made predictions about where and under what temperature conditions small (< size at 50% maturity) versus large (> size at 50% maturity) lobsters would brood. We found that although small female lobsters were abundant in Muscongus Bay, most were not ovigerous. Small ovigerous lobsters tended to spawn and remain inside the bay where they brooded at lower winter, but higher spring and summer temperatures than large ovigerous lobsters. In contrast, large ovigerous lobsters (>size at 50% maturity) were relatively rare, but most were ovigerous. They tended to spawn at greater distances from shore and while many stayed near where they spawned, others achieved a maximum displacement of up to 240 km. Large ovigerous lobsters were at more moderate temperatures throughout the year regardless of how far they traveled. Both small and large ovigerous lobsters experienced (1) sufficiently low winter temperatures for successful ovarian maturation, and (2) approximately the same number of degree days for egg development.

The pest risk assessment scheme constructed by the European and Mediterranean Plant Protection Organisation (EPPO, 1997 and in prep.) provided the basis for the Great Britain NonNative Organism Risk Assessment scheme. The EPPO scheme closely follows the international standard for phytosanitary measures (ISPM 11) on pest risk analysis produced by the International Plant Protection Convention (IPPC) (FAO, 2003). IPPC standards are recognised by the Sanitary and Phytosanitary Agreement of the World Trade Organization (WTO, 1994). More information on the scheme is provided at www.nonnativespecies.org/downloadDocument.cfm?id=158.

The specimen was identified https://doi.org/10.3391/bir.2021.10.1.18 by both morphological and molecular means. This is the species’ first record from Received: 7 June 2020 the eastern Mediterranean Sea and Greece, and only the second for the whole basin.
