Moderate recreational oyster harvest has variable impacts on biophysical properties of reefs and reef‐associated fauna

open access: yesEcosphere, Volume 14, Issue 6, June 2023., 2023
Abstract Despite the popularity of recreational fishing, our understanding of the impacts of this type of harvest within marine ecosystems generally lags behind the well‐documented effects of commercial fisheries. Intertidal oysters serve as ecosystem engineers within otherwise soft‐bottom estuaries but may be disproportionately susceptible to harvest ...

Changes in water flow alter community dynamics in oyster reefs

open access: yesEcosphere, Volume 14, Issue 4, April 2023., 2023
Abstract Fluid (air or water) movements are key determinants of living systems from cellular to community levels of organization. Water flow can influence individual fitness and local population dynamics, but less is known about the collective response of natural communities to alteration in water flow because parameter responses to flow may be ...

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.

Epigean and hypogean Palaemonetes sp. (Decapoda, Palaemonidae) from Edwards Aquifer: An examination of trophic structure and metabolism

open access: yesSubterranean Biology, 2014
This study addresses the causes of the metabolic depression observed when examining the metabolism of hypogean versus epigean organisms. We examined the two current hypotheses regarding the cause of metabolic cave adaptation, a paucity of food and low ...

Effect of Stocking Density on Culture Efficiency and Physiological Indicators of Largemouth Bass (Micropterus salmoides) under Recirculating Water Conditions in Land‐Based Round Ponds

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
To identify the optimal stocking rate of Micropterus salmoides culture in a land‐based round pond recirculating aquaculture system, five stocking densities were tested, i.e., D1–D5 with 60, 70, 80, 90, and 100 fish/m2, respectively. The water temperature of the experimental pond was 20.0–26.5°C.
