The aim of this study is to a) identify species that can prey on eelgrass seeds, b) assess if seed predation is a major cause of the low seedling establishment observed along the west coast of Sweden, c) assess if seed burial can reduce seed losses and increase seedling establishment.

Mar 5, 2015 Eelgrass beds are important in bays and estuaries throughout the world. This sea slug follows slime trails to track both its prey and mates. 1977). Eelgrass meadows harbor a variety of species of infauna and epifauna that are known prey for many commercially valuable fish and invertebrates ( Irlandi. These results are consistent with the hypothesis that ambush predators reduce the value of seagrass habitat for their prey relative to neighboring bare sediment Oct 15, 2018 digging up native vegetation as they burrow for shelter or dig for prey.

When the test item appears to be toxic to the prey, an increased feeding rate and/or an alternative food source should be considered. När testämnet förefaller

Temperate eelgrass beds are temporally and spatially complex habitats that often provide a transition habitat for many species of juvenile fishes. The feeding habits of young-of-the-year Black Rockfish (Sebastes melanops) and Copper Rockfish (S. caurinus) inhabiting eelgrass (Zostera marina) beds in Humboldt Bay, California, were assessed in 2003 and 2004. A total of 16 prey types were noted
(Photo by Ron Eby) Crabs are a favorite prey item for sea otters in Elkhorn Slough. (Photo by Ron Eby) Both sea slugs and Idotea (the crustacean between the two sea slugs above) feed on algae and increase in numbers when the crab population is controlled by sea otters. Lascara, Joseph, "Fish predator-prey interaction in areas of eelgrass (Zostera marina)" (1981). Dissertations, Theses, and Masters Projects. Eelgrass epifauna suggested a correspondence between diets and invertebrates produced in eelgrass but infauna and neuston results are needed to fully characterize prey availability. Knowing where, when, and how eelgrass benefits salmon is relevant to both salmon and eelgrass restoration.
4. The meadows of eelgrass found in lagoons along the Atlantic seacoast have a long history of providing a habitat for fish and invertebrates of many species. Despite this long history, it has proven difficult to document and quantify the relationships between eelgrass cover and the abundance of fish and crabs on a larger scale. An article in the current issue of the journal Marine Ecology
I found consumption of 94 different prey items, the majority of which are estuary derived, and benthic prey were most frequently consumed.

Migratory waterfowl such as brants, redheads, widgeons, black ducks and Canada geese feed on eelgrass, as do green turtles. Although they do not feed on eelgrass, cownose rays destroy eelgrass beds in many areas as they root through bottom sediments for their prey.
