These have areas of seagrass interspersed with bare sandy/mud.
These areas are subject to much recreational use and provide good opportunities
for hand netting and snorkelling. To avoid disturbing the vegetation hand
netters can walk along the bare sand and net off the side over the seagrass.
Inshore - there are often large amounts of dead seagrass.
Seagrass litter can
limit hand netting but it provides nutrients for large numbers of crustaceans
which are food for inshore fish and larval. The artificial habitats in the corners
of Marinas are great
spots for hand netting and often have exceptionally high populations
of pipefish, and
other
inshore demersal fish.
These high populations could be a result of high food levels provided by
rotting vegetation, combined with low predation due to a small area of
atypical and isolated habitat. In some high energy coastlines marinas will
yield examples of juveniles of deeper water, and consequently rare
species. |
