Stormwater Best Management Practices for MarinasOHSU-POST-1516 ABSTRACT:In 2008, the Ohio EPA implemented the National Pollutant Discharge Elimination System (NPDES) General Permit for Industrial Activity from Marinas. The permit covers any marinas in Ohio that conduct industrial boat maintenance activities including rehabilitation, repair, painting and certain equipment cleaning operations. The Ohio Clean Marinas Program is a proactive partnership designed to encourage marinas to use simple, innovative solutions to keep Ohio’s coastal and inland waterway resources clean. The basic goal of the program is environmental stewardship by making marina operators more aware of environmental laws, rules and jurisdictions. The Best Management Practices (BMP) Guidebook discusses specific practices that marinas should voluntarily implement to control impacts to water quality and habitat from marina operation and maintenance activities. A case study of Piedmont Marina in Freeport, Ohio was developed to highlight successful stormwater BMPs and provide guidance for retrofitting existing marinas to comply with NPDES requirements or to improve water quality.

To Eat or Not to Eat? Feeding and Growth Strategies in Neonatal Lake Erie WatersnakesOHSU-POST-1512 ABSTRACT:Early growth has major impacts on life characteristics such as survival and reproduction in vertebrate taxa. Consequently, most New World natricine snakes begin feeding and growing immediately after birth and can reach sexual maturity by their second year. Previous studies of the demography, diet, and behavior of the Lake Erie Watersnake (Nerodia sipedon insularum) have shown that this natricine differs by growing more slowly and delaying maturity until the third or fourth year. A plot of snout-vent-length vs. day of year for the youngest age class suggests there is no growth in the period preceding the snakes’ first hibernation, and prey has never been recovered from a neonate in the field. This suggests that in contrast to other natricines, Lake Erie Watersnakes delay feeding and growth until after emergence from their first hibernation. I investigated this delayed feeding in three parts by performing feeding trials with pre- and post-hibernation neonates, continuing field prey studies, and quantifying energy reserves available to young snakes in the form of yolks and fat bodies. For the feeding trials, binary logistic regression analysis detected a significant positive relationship between age of neonate and probability of feeding. This was reinforced by a sharp increase in field prey consumption by post-hibernation neonates. Comparison of fat reserves revealed that Lake Erie Watersnakes have significantly larger combined yolks and fat bodies than other neonatal natricines, suggesting a possible mechanism for delaying growth and feeding until after the first hibernation.

Gene Diversification of an Emerging Pathogen: A Decade of Mutation in a novel Fish Viral Hemorrhagic Septicemia (VHS) substrain since its first appearance in the Laurentian Great LakesOHSU-POST-1511 ABSTRACT:“Viral Hemorrhagic Septicemia virus (VHSv) is an RNA rhabdovirus that causes one of the world’s most serious fish diseases, infecting >80 species across the Northern Hemisphere. A novel and virulent substrain, IVb, first appeared in the Laurentian Great Lakes about a decade ago, resulting in massive fish kills, rapid spread, and genetic diversification. We analyzed temporal and spatial mutational patterns in the non-virion (Nv), glycoprotein (G), phosphoprotein (P), and matrix (M) genes. Our results show the Nv-gene has been evolving the fastest, with the G-gene second fastest. P- and M- genes are evolutionarily conserved and display slower rates of change. Samples from Lakes Erie and Ontario contained the greatest haplotype diversity. Since the 2006 outbreak, variants have increased in number, perhaps in response to fish populations developing resistance. Rapid evolutionary differentiation may allow new variants to evade fish host recognition and immune responses, facilitating persistence along with geographic expansion.” Download (5.29 MB) Full Detail Page |

Copper Concentrations at Lake Erie Marinas: Working together to understand and find solutions for nonpoint source pollutionOHSU-POST-1501Poster presenting the preliminary results of an Ohio Sea Grant research project on copper concentrations in Lake Erie marina sediments. ABSTRACT:One of the recent and challenging topics in the marina industry is managing wastewater from boat bottom washing. After the ban of tributyltin in the 1980s, copper became the primary biocide used in antifouling paints. The effects of copper on aquatic organisms have been well documented in the scientific community, and copper is listed on the Agency for Toxic Substances & Disease Recovery’s Priority List of Hazardous Substances. Copper oxide leaches from the boat bottom surface, often entering the water as a free copper ion and adsorbing suspended particulate matter as it settles and accumulates in the sediment. As a result, copper concentrations in sediment are often two to three orders of magnitude greater than in the water column. Ohio Sea Grant collaborated with Bowling Green State University and Lake Erie marinas to establish preliminary data on copper accumulation in sediment over the course of one boating season, and to quantify the amount of copper contributed by boat bottom washing during that season. Sediment samples were taken at 8 marinas along Lake Erie, at three targeted locations: the boat haul-out area, permanent dockage, and at the mouth of the marina. The project aided scientists, agencies, marina owners, and boaters in obtaining a better picture of the contribution of boat bottom wash wastewater to copper concentrations in Lake Erie nearshore sediments, and in finding sustainable solutions for boat bottom washing.
