Evaluating biodegradable alternatives to plastic mesh for small‐scale oyster reef restoration

open access: yesRestoration Ecology, Volume 31, Issue 3, March 2023., 2023
Polyethylene plastic mesh is commonly used for containing oyster shells in small‐scale oyster reef restoration, but environmental and public health concerns have prompted investigations of biodegradable alternatives. Shallow (<0.5 m) and deep (approximately 1 m) oyster reefs (approximately 6 m2) were constructed in the Mission‐Aransas Estuary, Texas, U.

Benthic Macrofauna Associated with Submerged Bottoms of a Tectonic Estuary in Tropical Eastern Pacific

open access: yesJournal of Marine Sciences, Volume 2011, Issue 1, 2011., 2011
The composition and distribution of the main associations of submerged macrobenthos of Bahía Málaga (Colombian pacific coast), were studied in relation to the distribution of hard and soft substrates and some abiotic factors. Eight localities were sampled during six months: three in the external border of the estuary and five in the inner part.
