“…However, the effects of other environmental factors, such as oxygen saturation, temperature, turbidity and windspeed, on schooling behaviour have rarely been investigated (see Weetman et al (1998Weetman et al ( , 1999 for the effect of temperature on schooling behaviour). The present results for one of these environmental factors, oxygen, the depletion of which along coastal areas is on the increase (Pihl et al 1991;Breitburg 1992;Cloern 2001), indicate that schooling behaviour may be affected by factors other than those directly related to predator-prey relationships (e.g. the presence of a predator) or sensory systems (e.g.…”

“…Direct and indirect physiological responses to hypoxia in fishes are well documented and the effect of hypoxia may include species-specific impacts on fish distribution, behaviour, feeding rate, competition and vulnerability to predators (Burton et al 1980;Coutant 1985;Kramer 1987;Pihl et al 1991Pihl et al , 1992Breitburg 1992;Breitburg et al 1994). Hypoxic conditions are usually found in coastal areas, and both benthic and pelagic fishes may be subject to hypoxia at some time during their lives.…”

The effect of progressive hypoxia on the structure and dynamics of herring (Clupea harengus) schools in laboratory conditions was investigated. The length, width and depth of schools of about 20 individuals were measured from video recordings to test the hypothesis that during hypoxia fish schools change their shape and volume. School shape (calculated as the ratios of length/depth, width/depth and length/width) did not change significantly during hypoxia. School length, width, depth, area and volume were all significantly increased at 20% oxygen saturation. Volume, area and width were more sensitive to hypoxia; volume and width were also increased at 25% and area at 30% oxygen saturation.The degree of position changing (shuffling) of individuals within the school was also analysed. Shuffling in normoxia was observed to occur largely through 'O-turn' manoeuvres, a 360°turn executed laterally to the school that allowed fishes in the front to move to the back. O-turn frequency during normoxia was 0.69 O-turns fish Ϫ1 min Ϫ1 but significantly decreased with hypoxia to 0.37 O-turns fish Ϫ1 min Ϫ1 at 30% oxygen saturation. Shuffling was also investigated by measuring the persistence time of individual herring in leading positions (i.e. the first half of the school). No significant changes occurred during hypoxia, indicating that the decrease in O-turn frequency does not affect shuffling rate during hypoxia, and that position shuffling in hypoxic conditions is mainly due to overtaking or falling back by individual fishes.School integrity and positional dynamics are the outcome of trade-offs among a number of biotic factors, such as food, predator defence, mating behaviour and various physical factors that may impose certain limits. Among these, our results indicate that oxygen level modulates schooling behaviour. Oxygen alters whole-school parameters at oxygen saturation values that can be encountered by herring in the field, indicating that oxygen availability is an important factor in the trade-offs that determine school volume. An increase in school volume in the wild may increase the oxygen available to each individual. However, shuffling rate is not affected by hypoxia, indicating that the internal dynamics of positioning is the result of the balance of other factors, for example related to the nutritional state of each individual fish as suggested by previous studies.

“…areas with dissolved oxygen concentration < 2 mg l -1 ) on fishes are well docu- mented, often resulting in behavioral avoidance or reduced growth or survival (Pihl et al 1991, Eby & Crowder 2002). We did not observe significant effects of dissolved oxygen concentration on the distribution of either age class of red drum from the gill net survey, but subadult red drum CPUE was positively related to dissolved oxygen levels in Hancock Creek.…”

For migratory fishes that occupy multiple habitats, surveys conducted at different scales may be required to assess habitat use. We used generalized additive models (GAMs) to relate water quality, microhabitat, geographic, and temporal factors to catches of 2 age classes of subadult red drum Sciaenops ocellatus from a 6 yr fishery-independent gill net survey in North Carolina, USA. Age-1 and age-2 red drum were most often caught in shallow, nearshore waters; in some regions, both showed a preference for seagrass. Age-1 red drum were primarily captured at 2 different salinity ranges (0 to 5 and 20 to 30 psu), while age-2 red drum abundance was not related to salinity. A smaller-scale analysis of 36 telemetered age-2 red drum in a small tributary of the Neuse River showed a negative response to salinity, a positive response to dissolved oxygen, a dome-shaped response to prey evenness, and a positive response to total prey. Although subadult red drum can tolerate a wide variety of environmental conditions, our research suggests that they associate with both abiotic and biotic factors in very specific ways. Habitat use patterns of subadult red drum were age-, scale-, and sometimes region-dependent, highlighting the need for examining habitat use patterns of estuarine organisms at multiple life history stages and scales if generalities about how species respond to abiotic and biotic factors are sought.

“…Therefore, groundfish in Saanich Inlet must retreat to shallower regions when the depth at which hypoxia occurs rises, and they return to deeper waters only once hypoxia subsides. Pihl et al (1991) describe similar fish behavior in Chesapeake Bay. In an intermittently anoxic basin such as Saanich Inlet, this groundfish movement would alter the areas of biologically reworked and resuspended seafloor.…”

Resuspension by fish facilitates the transport and redistribution of coastal sediments

Oxygen availability restricts groundfish to the oxygenated, shallow margins of Saanich Inlet, an intermittently anoxic fjord in British Columbia, Canada. New and previously reported 210 Pb measurements in sediment cores compared with flux data from sediment traps indicate major focusing of sediments from the oxygenated margins to the anoxic basin seafloor. We present environmental and experimental evidence that groundfish activity in the margins is the major contributor to this focusing. Fine particles resuspended by groundfish are advected offshore by weak bottom currents, eventually settling in the anoxic basin. Transmittance and sediment trap data from the water column show that this transport process maintains an intermediate nepheloid layer (INL) in the center of the Inlet. This INL is located above the redox interface and is unrelated to water density shifts in the water column. We propose that this INL is shaped by the distribution of groundfish (as resuspension sources) along the slope and hence by oxygen availability to these fish. We support this conclusion with a conceptual model of the resuspension and offshore transport of sediment. This fish-induced transport mechanism for sediments is likely to enhance organic matter decomposition in oxygenated sediments and its sequestration in anoxic seafloors.
