River Damming Impacts on Fish Habitat and Associated Conservation Measures

Reviews of Geophysics, Volume 61, Issue 4, December 2023., 2023
Abstract River damming has brought great benefits to flood mitigation, energy and food production, and will continue to play a significant role in global energy supply, particularly in Asia, Africa, and South America. However, dams have extensively altered global river dynamics, including riverine connectivity, hydrological, thermal, sediment and ...

DNA metabarcoding assessment of Neotropical ichthyoplankton communities is marker‐dependent

Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023
DNA metabarcoding has been applied as a rapid, cost‐effective, and accurate taxonomy tool, allowing the identification of multiple individuals simultaneously. The combined use of the three markers increased the genera detection rates by 25%–87.5%, allowing an increased taxonomic coverage and robust taxonomic identification of complex Neotropical ...

Dynamic Adaptive Environmental Flows (DAE‐Flows) to Reconcile Long‐Term Ecosystem Demands With Hydropower Objectives

Water Resources Research, Volume 59, Issue 7, July 2023., 2023
Abstract This study investigates how environmental flows (e‐flows) can be designed as dynamic operating policies to optimize long‐term economic and ecosystem performance in reservoir systems. The main goal is to provide e‐flow solutions that contribute to better preparedness and flexibility of hydro‐systems to face multiyear stress periods, reducing ...

Isotopic turnover in polar cod (Boreogadus saida) muscle determined through a controlled feeding experiment

Journal of Fish Biology, Volume 102, Issue 6, Page 1442-1454, June 2023., 2023
Abstract Polar cod (Boreogadus saida) is an important trophic link within Arctic marine food webs and is likely to experience diet shifts in response to climate change. One important tool for assessing organism diet is bulk stable isotope analysis. However, key parameters necessary for interpreting the temporal context of stable isotope values are ...

Development of gluten-free fish (Pseudoplatystoma corruscans) patties by response surface methodology [PDF]

Journal of Food Science and Technology, 2018
The goal of this study was to develop a fish-based product suitable for people with celiac disease. Water and gluten-free flours (rice, corn, amaranth or quinoa) were added to improve cooking yield, texture parameters and as an aid in improving quality attributes such as taste and juiciness.

Sustainable management and improvement of genetic resources for aquaculture

Journal of the World Aquaculture Society, Volume 54, Issue 2, Page 364-396, April 2023., 2023
Abstract Effective genetic management of the ~700 aquatic species cultured globally should be addressed for aquaculture to make a significant contribution towards meeting the UN's Sustainable Development Goals. This article aims to identify the current status and challenges relating to the management of farmed aquatic genetic resources (AqGR) and to ...
