INTRODUCTION the Peruvian "Lead Snail"
RADIATION DECONTAMINATION OF PERUVIAN MARINE "LEAD SNAIL" (THAIS CHOCOLATA) INOCULATED WITH VIBRIO CHOLERAE Ol EL TOR Z. TORRES Instituto Peruano de Energia Nuclear XA0100965 F. ARIAS Universidad Nacional del Centro del Peru Peru Abstract In vivo studies were conducted using marine snails (Thais chocolatd) artificially contaminated in a tank containing sea water inoculated with a pure culture of Vibrio cholerae, such that 105 colony forming units per gram (CFU/g) were uptaken by the mollusks in 1.5 h. A radiation Di0 value of 0.12 kGy was determined for V. cholerae upon subsequent irradiation of the live snails at doses in the range 0.0-4.0 kGy. A second series of tests were conducted using naturally contaminated, non-inoculated snails, shelled and packaged simulating commercial procedures, irradiated at 0.0-3.0 kGy, and stored at 2-4°C. These tests indicated that a dose of 2.0 kGy was optimal to extend the microbiological shelf- life of the snails to 21 days without inducing significant adverse sensory or chemical effects. Non- irradiated snails similarly treated and stored spoiled after only seven days. INTRODUCTION The Peruvian "lead snail" (Thais chocolatd) is a mollusk having a single, heavy, large and wide valve, uniformly brown in color, from which an orange internal columnella and bluish interior can be observed. Its average size is 88-mm long by 35-mm dia. (Rosales, 1988). This snail is typically found in marine rocky beds, where it forms banks at a depth of some 30 m, affixing itself to rocks in temperate waters (15-17°C). -

Life in the Fast Lane – from Hunted to Hunter Middle School Version
Life in the Fast Lane: From Hunted to Hunter Lab Activity: Dissection of a Squid-A Cephalopod Middle School Version Lesson by Kevin Goff Squid and octopi are cephalopods [say “SEFF-uh-luh-pods”]. The name means “head-foot,” because these animals have VIDEOS TO WATCH gripping, grasping arms that emerge straight from their heads. Watch this short clip on the Shape of Life At first glance, they seem totally different from every other website to become familiar with basic mollusc anatomy: creature on Earth. But in fact, they are molluscs, closely related • “Mollusc Animation: Abalone Body to snails, slugs, clams, oysters, mussels, and scallops. Like all Plan” (under Animation; 1.5 min) modern day molluscs, cephalopods descended from simple, Note the abalone’s foot, radula, and shell- snail-like ancestors. These ancient snails crept sluggishly on making mantle. These were present in the seafloor over 500 million years ago. Their shells resembled the snail-like ancestor of all molluscs an umbrella, probably to shield them from the sun’s intense ultraviolet radiation. When all sorts of new predators appeared on the scene, with powerful jaws or crushing claws, a thin shell was no match for such weapons. Over time, some snails evolved thicker shells, often coiled and spiky. These heavy shells did a better job of fending off predators, but they came with a price: They were costly to build and a burden to lug around. These snails sacrificed speed for safety. This lifestyle worked fine for many molluscs. And, still today, nearly 90% of all molluscs are heavily armored gastropods that crawl around at a snail’s pace. -
Impact of the the COVID-19 Pandemic on a Queen Conch (Aliger Gigas) Fishery in the Bahamas
Impact of the the COVID-19 pandemic on a queen conch (Aliger gigas) fishery in The Bahamas Nicholas D. Higgs Cape Eleuthera Institute, Rock Sound, Eleuthera, Bahamas ABSTRACT The onset of the coronavirus (COVID-19) pandemic in early 2020 led to a dramatic rise in unemployment and fears about food-security throughout the Caribbean region. Subsistence fisheries were one of the few activities permitted during emergency lockdown in The Bahamas, leading many to turn to the sea for food. Detailed monitoring of a small-scale subsistence fishery for queen conch was undertaken during the implementation of coronavirus emergency control measures over a period of twelve weeks. Weekly landings data showed a surge in fishing during the first three weeks where landings were 3.4 times higher than subsequent weeks. Overall 90% of the catch was below the minimum legal-size threshold and individual yield declined by 22% during the lockdown period. This study highlights the role of small-scale fisheries as a `natural insurance' against socio-economic shocks and a source of resilience for small island communities at times of crisis. It also underscores the risks to food security and long- term sustainability of fishery stocks posed by overexploitation of natural resources.

Sustainable Shellfishshellfish Recommendations for Responsible Aquaculture
SustainableSustainable ShellfishShellfish Recommendations for responsible aquaculture By Heather Deal, M.Sc. As Sustainable Shellfish went to press, the B.C. Ministry of Agriculture, Food and Fisheries (MAFF) pulled their draft Code of Practice for Shellfish Aquaculture from circulation. This document, upon which much of Sustainable Shellfish is based, was one component in guiding, monitoring, and reg- ulating B.C.’s rapidly growing shellfish industry. The Code was by no means exhaustive – Sustainable Shellfish aims to address its gaps and limitations, including its lack of con- sideration for stringent environmental safeguards on the expanding industry. Now that the Code of Practice has been abandoned by gov- ernment, the shellfish industry is managed via complaints to the Farm Industry Review Board. This board uses "normal farm practices" as a standard, but does not and, according to MAFF, will not define what "normal farm practices" are with regard to aquaculture. In other words, although there is leg- islation in place, there are no longer governmental stan- dards or guidelines specific to this industry. The BC Shellfish Growers Association (BCSGA) does have an Environmental Management System and Code of Practice, which is very similar to that which MAFF pro- duced. The BCSGA Code is not available on their website, so please contact the association directly to request a copy: #7 - 140 Wallace Street Nanaimo, BC V9R 5B1 Tel: (250) 714-0804 Fax: (250) 714-0805 Email: [email protected] The draft government Code of Practice is still available on the David Suzuki Foundation website, www.davidsuzuki.org/oceans. Sustainable Shellfish, used in conjunction with the non- operational Code offers a way forward towards a low impact industry with minimal harmful effects on B.C.’s marine environment and coastal communities. -
Opinion Why Do Fish School?
Current Zoology 58 (1): 116128, 2012 Opinion Why do fish school? Matz LARSSON1, 2* 1 The Cardiology Clinic, Örebro University Hospital, SE -701 85 Örebro, Sweden 2 The Institute of Environmental Medicine, Karolinska Institute, SE-171 77 Stockholm, Sweden Abstract Synchronized movements (schooling) emit complex and overlapping sound and pressure curves that might confuse the inner ear and lateral line organ (LLO) of a predator. Moreover, prey-fish moving close to each other may blur the elec- tro-sensory perception of predators. The aim of this review is to explore mechanisms associated with synchronous swimming that may have contributed to increased adaptation and as a consequence may have influenced the evolution of schooling. The evolu- tionary development of the inner ear and the LLO increased the capacity to detect potential prey, possibly leading to an increased potential for cannibalism in the shoal, but also helped small fish to avoid joining larger fish, resulting in size homogeneity and, accordingly, an increased capacity for moving in synchrony. Water-movements and incidental sound produced as by-product of locomotion (ISOL) may provide fish with potentially useful information during swimming, such as neighbour body-size, speed, and location. When many fish move close to one another ISOL will be energetic and complex. Quiet intervals will be few. Fish moving in synchrony will have the capacity to discontinue movements simultaneously, providing relatively quiet intervals to al- low the reception of potentially critical environmental signals. Besides, synchronized movements may facilitate auditory grouping of ISOL. Turning preference bias, well-functioning sense organs, good health, and skillful motor performance might be important to achieving an appropriate distance to school neighbors and aid the individual fish in reducing time spent in the comparatively less safe school periphery. -

Appeldoorn Appeldoom, R. S. 1995. Potential depensatory mechanisms operating on repro ductive output in gonochoristic molluscs, with particular reference to strombid gastro pods. - ICES mar. Sei. Symp., 199: 13-18. Molluscs are typically sessile or slow moving, yet successful reproduction requires close proximity to potential mates. Three mechanisms are identified whereby repro ductive potential of a population can be limited under conditions of low density. The first is the reduction in numbers of spawners as abundance decreases. The second reflects the difficulty in finding mates, and takes the form of either (1) search time for slow but motile species, or (2) wasted spawning (or non-spawning) for sessile species, where gametes are not fertilized. The third mechanism is a breakdown of a positive feedback loop between contact with males (either direct or through chemical cues) and rate of gametogenesis and spawning in females, i.e., sexual facilitation. The second and third mechanisms are functions of local density, rather than overall abundance. Literature review and present studies on strombid gastropods indicate the potential for these mechanisms to occur. Many species are characterized by behaviours, such as aggregative settlement, that serve to overcome this problem. Intensive fishing prac tices may invoke these depensatory mechanisms as local density and abundance are reduced, thereby increasing the chance of recruitment failure. Richard S.
