Infectious Necrotizing Enteritis And Mortality Caused By Vibrio Carachariae In Summer Flounder Paralichthys Dentatus During Intensive Culture, Bruno Soffientino, Todd Gwaltney, David R. Nelson, Jennifer L. Specker, Michael Mauel, Marta Gomez-Chiarri Apr 2013

Infectious Necrotizing Enteritis And Mortality Caused By Vibrio Carachariae In Summer Flounder Paralichthys Dentatus During Intensive Culture, Bruno Soffientino, Todd Gwaltney, David R. Nelson, Jennifer L. Specker, Michael Mauel, Marta Gomez-Chiarri

An epizootic causing mortality among cultured summer flounder Paralichthys dentatus occurred in summer of 1998 at a land-based facility on Narragansett Bay, Rhode Island, USA. The disease, flounder infectious necrotizing enteritis (FINE), was characterized by reddening around the anal area, distended abdomens filled with opaque serosanguineous fluid, enteritis and necrosis of the posterior intestine. In extreme cases of the disease, the posterior intestine was detached from the anus and was observed coming out the vent. The intestine of individuals that recovered from the dsease ended in a blind-sac; the abdomens of these fish were distended, due to food and water …


Spatial And Temporal Variation In Otolith Chemistry For Tautog (Tautoga Onitis) In Narragansett Bay And Rhode Island Coastal Ponds, Ivan Mateo, Edward G. Durbin, David A. Bengtson, Richard Kingsley, Peter K. Swart, Daisy Durant Apr 2013

Spatial And Temporal Variation In Otolith Chemistry For Tautog (Tautoga Onitis) In Narragansett Bay And Rhode Island Coastal Ponds, Ivan Mateo, Edward G. Durbin, David A. Bengtson, Richard Kingsley, Peter K. Swart, Daisy Durant

The elemental composition of otoliths may provide valuable information for establishing connectivity between fish nursery grounds and adult fish populations. Concentrations of Rb, Mg, Ca, Mn, Sr, Na, K, Sr, Pb, and Ba were determined by using solution-based inductively coupled plasma mass spectrometry in otoliths of young-of-the year tautog (Tautoga onitis) captured in nursery areas along the Rhode Island coast during two consecutive years. Stable oxygen (δ18O) and carbon (δ13C) isotopic ratios in young-of-the year otoliths were also analyzed with isotope ratio mass spectrometry. Chemical sig natures dif fered sig nif icantly among the distinct nurseries within Narragansett Bay and …

Climate change, understood as a statistically significant variation in the mean state of the climate or its variability, is the greatest environmental challenge of this generation (Intergovernmental Panel on Climate Change, 2001). Marshfield is already being affected by changes in the climate that will have a profound effect on the town’s economy, public health, coastal resources, natural features, water systems, and public and private infrastructure. Adaptation strategies have been widely recognized as playing an important role in improving a community’s ability to respond to climate stressors by resisting damage and recovering quickly. Based on review of climate projections for the …


Evaluation Of The In Situ Ichthyoplankton Imaging System (Isiis): Comparison With The Traditional (Bongo Net) Sampler, Robert K. Cowen, Adam T. Greer, Cedric M. Guigand, Jonathan A. Hare, David E. Richardson, Harvey J. Walsh Dec 2012

Plankton and larval fish sampling programs often are limited by a balance between sampling frequency (for precision) and costs. Advancements in sampling techniques hold the potential to add considerable efficiency and, therefore, add sampling frequency to improve precision. We compare a newly developed plankton imaging system, In Situ Ichthyoplankton Imaging System (ISIIS), with a bongo sampler, which is a traditional plankton sampling gear developed in the 1960s. Comparative sampling was conducted along 2 transects ~30–40 km long. Over 2 days, we completed 36 ISIIS tow-yo undulations and 11 bongo oblique tows, each from the surface to within 10 m of …
