“…Though several fish species are resident in marsh ponds in the Sheepshead Meadows marsh (e.g. F. luciae, Gasterosteus aculeatus, Cyprinodon variegatus, Lucania parva, Menidia beryllina;Szedlmayer & Able 1996, Able et al 2005, the mummichog is the most abundant fish species inhabiting marsh ponds in New Jersey (Able & Szedlmayer 1996). We sampled mummichog populations in 6 marsh ponds adjacent to the Rutgers University Marine Field Station (RUMFS; Fig.…”

“…We speculate that immigration into marsh ponds in the spring may have been driven by adults from other overwintering sites such as other ponds (Smith & Able 1994) or creeks and basins (Able & Fahay 1998). Some of these may have been entering to spawn, as it is known that marsh ponds provide suitable habitat for larval fish (Able et al 2005.…”

Fish respond to habitat and demographic factors that affect growth and survival through migration, reproduction and mortality. However, the importance of migration rates on fish population dynamics and the effects of habitat and demographic factors on movement are not well understood. We used mark-recapture to determine population dynamics (recruitment, mortality, immigration and emigration) of the mummichog Fundulus heteroclitus inhabiting semi-isolated ponds in a New Jersey salt marsh over the spring and summer of 2002. We tested the effects of marsh pond flood frequency, water temperature and fish density on mummichog emigration from marsh ponds. Results show that during the April to July study period, monthly emigration rates averaged 30% and tended to decline from spring to summer in most ponds. Recruitment and immigration were negligible after May and June, respectively. Increasing mortality and decreasing emigration and immigration over the study period suggested that there was a shift in the importance of movement in regulating mummichog population size in marsh ponds. The mean rate of emigration showed a significant negative relationship with the frequency of flooding in a pond. Neither mummichog density nor water temperature was strongly correlated with emigration rate. Our finding of lower emigration from ponds with higher flooding frequency suggests that frequent pond flooding indirectly triggers stationary behaviour in mummichogs because of enhanced water quality and food abundance.

“…Previous writers have indicated the value of natural saltmarsh habitats as fish refuge and feeding areas, particularly in various USA states such as North and South Carolina (Shenker & Dean, 1979;Bozeman & Dean, 1980;Hettler, 1989), Virginia (Weinstein & Brooks, 1983;Rozas & Odum, 1987), Georgia (Kneib & Wagner, 1994), New Jersey (Able et al, 2005) and Delaware Nemerson & Able, 2003); as well as in South Africa (Paterson & Whitfield, 2000), South Australia (Connolly, 1994;Bloomfield & Gillanders, 2005) and Italy (Franco et al, 2006). However, the majority of this work is not directly applicable to UK saltmarshes which have a larger tidal range and where the creeks drain fully on every tide (see Cattrijsse & Hampel, 2006 for a review).…”

Variations in the feeding of 0-group bass Dicentrarchus labrax (L.) in managed realignment areas and saltmarshes in SE England

The diets of 0-group bass Dicentrarchus labrax were investigated in SE England in the Blackwater Estuary: three managed realignment sites at Tollesbury, Abbotts Hall and Orplands; and two established saltmarshes at Tollesbury and Abbotts Hall. In Summer, small 0-group (15-30 mm) bass consumed calanoid and harpacticoid copepods predominantly and left the sites significantly fuller than on entering them (Mann-Whitney, W = 5837, P \ 0.001). In Summer, large 0-group (30-59 mm) bass consumed benthic prey, predominantly Carcinus maenas, Nereis spp. and amphipods. These larger bass left Tollesbury managed realignment site, and the established saltmarshes at Tollesbury and AbbottsHall, significantly fuller than on entry (MannWhitney, W = 1116, 372 and 229, respectively, all P \ 0.05), unlike at the Abbotts Hall and Orplands managed realignment sites where they had less time to feed. Early site access and soft sediments for macroinvertebrates improved bass feeding opportunities. A wider range of prey was exploited by large 0-group bass in Autumn than in Summer (ANOSIM, R = 0.093, P \ 0.05) including organisms associated with the vegetation such as chironomids and fulgoromorphs. Microhabitat differences influence the feeding of this recreationally and commercially important species during one of its most vulnerable life stages, however by Autumn, these site differences are mitigated by the opportunistic feeding of 0-group bass.

“…Tide pools are often subjected to dramatic physical and chemical changes with the ebb and flow of the tide. Salinity, pH and dissolved oxygen can alter rapidly, and temperature can have daily ranges in excess of 15° C (Able et al , 2005). Pool dwelling organisms must accommodate this variable environment if they are to take advantage of this resource.…”

The feeding ecology of two sympatric gobies, Favonigobius lentiginosus and Favonigobius exquisitus, which inhabit soft substrate pools was studied in Moreton Bay, Australia. Favonigobius spp. and sediment cores were collected from three locations within the bay and fish gut contents were analysed to explore potential competition and ontogenetic dietary shifts. The most abundant prey at all sites was nematodes at 6.33 ± 0.38 cm(-3) at Dunwich, 33.58 ± 0.26 cm(-3) at Manly and 6.36 ± 0.849 cm(-3) (mean ± S.E.) at Godwin Beach. Nevertheless, they were not a dominant component of the diets. Volumetric percent contribution of prey showed that copepods and decapod shrimps dominated F. lentiginosus diets at Dunwich (7.8 and 6.6%, respectively) and Godwin Beach (6.5 and 14.3%, respectively) and the diets of F. exquisitus at Manly (9.2 and 9.5%, respectively) and Godwin Beach (10.4 and 11.8%, respectively). Schoener's index of dietary overlap between the two species, when sympatric, was 0.85 indicating a high similarity. An ontogenetic shift towards larger prey items occurred as Favonigobius spp. reached larger sizes. Gut fullness indices showed significant differences between time of day (two-way ANOVA, P < 0.01) and species (two-way ANOVA, P < 0.05) but Bonferroni's multiple comparison test showed that the only significant difference was between F. lentiginosus at Dunwich and F. exquisitus at Godwin Beach at 1800 hours. Food resource competition and temporal resource partitioning did not appear to be a limiting factor between F. lentiginosus and F. exquisitus despite cohabitation in such restricted environments.
