Spatial Distribution Patterns of Clownfish in Recirculating Aquaculture Systems [PDF]

arXiv, 2021
Successful aquaculture systems can reduce the pressure and help secure the most diverse and productive Red Sea coral reef ecosystem to maintain a healthy and functional ecosystem within a sustainable blue economy. Interestingly, recirculating aquaculture systems are currently emerging in fish farm production practices. On the other hand, monitoring and

Chitosan, Gelatine, and Cellulose Based Hydrogels for the Removal of Potentially Toxic Elements from Aquaculture Water: A Comparative Study

Advanced Sustainable Systems, EarlyView.
Hydrogels made of chemically modified biopolymers are easy to prepare and cost‐effective, they have proven to be effective materials for the simultaneous removal of seven potentially toxic elements (PTEs) from ultrapure and real water samples. The cellulose‐based one seems the best for single treatments while the gelatine‐based one seems the most ...

Black Soldier Fly Larvae Meal vs. Soy Protein Concentrate Meal: A Comparative Digestibility Study in Barramundi (Lates calcarifer)

Aquaculture Nutrition
Black soldier fly larvae meal (BSFM) from Hermetia illucens has emerged as a dependable protein source in aquaculture. This study aimed to assess BSFM’s digestibility in barramundi juveniles and compare it to soy protein concentrate meal (SPCM).

Shrimp Virus Regulates ROS Dynamics via the Nrf2 Pathway to Facilitate Viral Replication

Advanced Science, EarlyView.
Viruses manipulate host ROS as a strategy to achieve successful infection. WSSV exploits Nrf2 pathway to maintain ROS homeostasis and establishes a positive feedback loop to facilitate WSSV replication. Wsv220 competitively binds to Keap1 to activate Nrf2. Nrf2 up‐regulates LvG6PDH to produce more NADPH and GSH to eliminate excessive ROS.

Water quality management in aquaculture

Cambridge Prisms: Water
The aquaculture industry requires good water quality for its successful operation but produces wastes that can cause environmental deterioration and pose high risks to the sector. Adequate waste treatment and recycling are necessary to make aquaculture a

An informed thought experiment exploring the potential for a paradigm shift in aquatic food production [PDF]

arXiv, 2021
The Neolithic Revolution began c. 10000 years ago and is characterised by the ultimate, near complete transition from hunting and gathering to agricultural food production on land. The Neolithic Revolution is thought to have been catalysed by a combination of local population pressure, cultural diffusion, property rights and climate change.

Reductive Supramolecular In Situ Construction of Nano‐Platinum Effectively Couples Cathodic Hydrogen Evolution and Anodic Alcohol Oxidation

Advanced Science, EarlyView.
The supramolecular framework reductant is developed to realize the in situ construction of highly dispersed ultrafine nano‐Pt. The nano‐Pt supported on the BCN carrier realizes multi‐scenario electrocatalytic water hydrogen production, and establish a high‐performance cathode hydrogen evolution‐anode methanol oxidation coupling system, presenting a low‐

Fish Fingerprinting: Identifying Crude Oil Pollutants using Bicyclic Sesquiterpanes (Bicyclanes) in the Tissues of Exposed Fish

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 7-18, January 2023., 2023
Abstract In the present study, we investigated the possibility of identifying the source oils of exposed fish using ratios of bicyclic sesquiterpane (bicyclane) chemical biomarkers. In the event of an oil spill, identification of source oil(s) for assessment, or for litigation purposes, typically uses diagnostic ratios of chemical biomarkers to produce

US employment exposure to domestic and foreign tariff changes under NAFTA

Applied Economic Perspectives and Policy, EarlyView.
Abstract Literature examining the effects of changes in trade agreements and import competition on US employment and wages has focused primarily on non‐agricultural industries and changes in US import tariffs. We propose a method for measuring worker exposure to changes in agricultural tariffs using a newly developed county‐level dataset of employment ...

Assessing the Impact of Chemical Algae Management Strategies on Anurans and Aquatic Communities

Environmental Toxicology and Chemistry, Volume 42, Issue 1, Page 213-224, January 2023., 2023
Abstract Pond management with chemical and biological agents that reduce overgrowth of algae is an important means of maintaining water quality in residential ponds, yet the effects on nontarget species are not fully understood. We assessed the impact of Aquashade (a common nontoxic pond dye) and copper sulfate (a toxic algaecide) on American toad ...
