Tidal and diurnal influence on food consumption of a salt marsh killifish Fundulus heteroclitus
TLDR
Feeding patterns during four 24-h periods, sampled at 3-h intervals, were investigated for the mummichog Fundulus heteroclitus, an important link in energy transfers between the marsh surface and subtidal systems, enhancing its own energy supplies by consuming marsh surface prey whenever available.Abstract:
Feeding patterns during four 24-h periods, sampled at 3-h intervals, were investigated for the mummichog Fundulus heteroclitus, in a Delaware, USA tidal marsh. Two factors potentially influencing feeding patterns, time of day and tide height, were examined. On 2 of the sampling periods a low tide occurred in the morning, while on the other 2 sampling periods a high tide occurred in the morning. Results are reported as g-dry wt. of food per g-dry wt. of fish. F. heteroclitus is primarily a daytime feeder that most actively feeds at high tide, regardless of whether or not the high tide inundates marsh surface areas. When tide height was sufficient to inundate the marsh surface, fish invaded these areas and consumed prey characteristic of the marsh surface. F. heteroclitus is an important link in energy transfers between the marsh surface and subtidal systems, enhancing its own energy supplies by consuming marsh surface prey whenever available.read more

Occupation of submerged aquatic vegetation by fishes: testing the roles of food and refuge
TL;DR: Data suggest that foraging profitability is significantly enhanced by feeding in the SAV, and fish consume larger prey and may have higher growth rates, lower mortality, and higher fecundity.

The value of salt marsh edge vs interior as a habitat for fish and decapod crustaceans in a Louisiana tidal marsh
G. W. Peterson,R. E. Turner +1 more
TL;DR: In this article, flume nets of various lengths and a 3m seine were used to sample fishes and macrocrustaceans using a flooded Louisiana salt marsh and the adjacent tidal creek and the experiment allowed for species-specific comparisons of the flooded marsh at the creek edge versus the interior.

Predation risk and use of intertidal habitats by young fishes and shrimp
TL;DR: The experimental results suggest that young killifishes and shrimp remain in the intertidal zone at low tide as an adaptation to avoid a high risk of mortality from concentrations of predatory adults in subtidal marsh habitats.

E. A. Irlandi,M. K. Crawford +1 more
TL;DR: Pinfish used in field experiments provided an important link between habitats, allowing transfer of marsh-derived secondary production to subtidal seagrass beds and vice versa, and to maximize secondary production and utilization of intertidal marshes.

TL;DR: In this paper, structural and functional interactions in a man-made and two natural marshes were compared by integrating substrate characteristics and marsh utilization by organisms of two trophic levels.

TL;DR: The first part of the general report, dealing with the fishes was published in 1925, as Bulletin of the United States Bureau of FisherIes, and subsequent parts describing the plankton of the offshore waters of the Gulf and the physical Characteristics of its waters were published in 1926-27, as Part 2. as discussed by the authors.
