The role of vegetation, drying, and rewetting on water and sediment phosphorus concentrations in an experimental ditch channel experiment

open access: yesAgrosystems, Geosciences &Environment, Volume 8, Issue 3, September 2025.
Abstract Intermittent drying and rewetting of agricultural drainage ditch networks along with vegetation presence play a significant role in phosphorus (P) fate and transport to the receiving water bodies. To examine how vegetation influences the response of P transport to drying and rewetting, we lined six low‐gradient (0.01% slope) stainless steel ...

Effect of three different feeding strategies on phytoplankton, zooplankton and benthos in pacific brown shrimp Penaeus californiensis (Holmes 1900) farming ponds

open access: yesCiencias Marinas, 1998
 An experimental study was conducted during 23 weeks in Bahia Kino, Sonora (Mexico), to evaluate the effect of three different feeding strategies used in the culture of Pacific brown shrimp, Penaeus californiensis, on the abundance of phytoplankton ...

Navigating Nitrofuran Challenges in Farmed Prawn (Macrobrachium rosenbergii): Strengthening Safety and Export Potentials in Bangladesh

open access: yesReviews in Aquaculture, Volume 17, Issue 4, September 2025.
ABSTRACT Nitrofuran metabolites, including semicarbazide, pose significant risks to food safety, particularly in the aquatic industry. Bangladesh's shrimp industry faced major challenges due to nitrofuran contamination, leading to a voluntary export suspension to the European Union (EU).

Blueprints for Riverine Cod Nest Boxes Draw From Multiple Design Considerations

open access: yesAquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT Designing aquatic nest boxes is rarely afforded detailed scientific account. Here we provide some historical context for nest boxes used in production of large‐bodied fishes of the Australian freshwater cod genus Maccullochella. Our experience with eastern freshwater cod is used as a case study to: (a) convey aspects of the complexity of the ...

Factors Driving Background Choice in Scorpionfish

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
Scorpionfishes are well camouflaged ambush predators. We use behavioural tests in combination with standardised photography and visual modelling to quantify camouflage parameters. We discuss the relevance of chromatic and achromatic cues in the fishes' natural environment for background choice and the potential use of different camouflage strategies ...

Unlocking the Depths: Use of a Trait‐Based Approach to Reveal the Diversity of Foraging Strategies in a Deep‐Pelagic Fish Community

open access: yesEcology and Evolution, Volume 15, Issue 8, August 2025.
The deep‐pelagic fish community showed differences in functional strategies along the depth gradient. Epipelagic species exhibited significant trait convergence with traits adapted to the prey‐tracking strategy, while bathypelagic species exhibited significantly higher functional richness values than expected at random.

Sea otter interactions with mariculture oyster farms

open access: yesThe Journal of Wildlife Management, Volume 89, Issue 6, August 2025.
Despite concerns about sea otter (Enhydra lutris) interactions with oyster farms in Alaska, our study found no significant differences in general activity or prey selection between farm and non‐farm areas. However, sea otter prey intake rates varied spatially, with clams, mussels, and crabs dominating their diet.
