The trophic ecology and structure of 5 benthic Antarctic fish communities were studied.Two locations at South Georgia Island, one the Sandwich Islands, two Orkney Islands sampled using a bottom trawl.Specles diversity was low with 13 or fewer species in each community pronounced dominance 3 per community.H' values < 1.3 all cases 0.8 3; e evenness 0.6 0.3 3.The Island had lowest (H' = 0.2), likely due to very limited prey spectrum, geographic isolation, geologically recent formation,...

The fish assemblage using shallow nursery habitats in the Ogeechee River-Ossabaw Sound salt-marsh estuary, Georgia, was investigated during winter and spring of two successive years. High river discharges these periods produced fully freshwater conditions (all tidal stages amplitudes) upper portion study area for up to 4 months.

The ratio of RNA to DNA (RNA:DNA) in white muscle tissue juvenile summer flounder ( Paralichthys dentatus ) and weakfish Cynoscion regalis was used as a proxy for recent growth rate an estuarine nursery. Variability RNA:DNA examined relative temporal changes temperature dissolved oxygen (DO). Initial laboratory experiments indicated (i) strong positive relationship between rate, (ii) rapid response feeding, (iii) no effect hypoxia on the (tested only). Diel cycling DO occurred nursery...
Age-0 Atlantic croakers Micropogonias undulatus overwinter in Mid-Atlantic Bight (MAB) estuaries, where interannual variability year-class strength is pronounced. Previous researchers have hypothesized that this the result of cold-induced winter mortality age-0 within estuarine nurseries. We tested hypothesis by means laboratory experiments designed to (1) estimate effects severity and duration on probability survival fish, (2) determine relationship between body size cold tolerance, (3)...

Areas of low flushing and high nutrient loading in shallow estuaries are susceptible to diel-cycling hypoxia also represent important nursery habitat for juvenile estuary-dependent fishes.

Abstract Application of algicides produced by naturally occurring bacteria is considered an environmentally friendly approach to control harmful algal blooms. However, few studies assess the effects bacterial on non-target species, either independently or with other stressors. Here, we measured sub-lethal dinoflagellate-specific algicide IRI-160AA estuarine fish Fundulus heteroclitus and Menidia menidia in laboratory experiments. Plasma cortisol levels were test whether a neuroendocrine...
