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 ...

Protein‐Sparing Effect of α‐Lipoic Acid in Diets with Different Protein/Carbohydrate Ratios for the Oriental River Prawn, Macrobrachium nipponense

Aquaculture Research, Volume 2023, Issue 1, 2023., 2023
Carbohydrates are commonly used in aquaculture feed because they are the cheapest energy source. Promoting carbohydrate catabolism for energy production can increase the dietary protein utilization efficiency (i.e., a protein‐sparing effect). Alpha‐lipoic acid (α‐LA) is a cofactor of some rate‐limiting key enzymes (pyruvate dehydrogenase complex and α ...

Effects of Dietary Lipid Levels on Growth, Digestive Enzyme Activities, Antioxidant Capacity, and Lipid Metabolism in Turbot (Scophthalmus maximus L.) at Three Different Stages

Aquaculture Nutrition, Volume 2022, Issue 1, 2022., 2022
Three 56‐day feeding trials were conducted to evaluate dietary lipid requirements and effects of dietary lipid levels on growth, digestive enzyme activities, antioxidant capacity, and lipid metabolism in turbot (Scophthalmus maximus L.) at three growth stages. The initial mean body weight of turbot was 9.13 ± 0.17 g, 50.10 ± 0.38 g, and 80.05 ± 0.76 g (

Development of Novel Gluten‐Free Sausage Based on Chickpea, Corn Flour, and HPMC

International Journal of Food Science, Volume 2022, Issue 1, 2022., 2022
The present work was carried out to study the effectiveness of substitution of wheat flour with different levels of chickpea flour, corn flour, and hydroxypropyl methylcellulose (HPMC) for the production of gluten‐free sausages. The prepared sausages were subjected to physicochemical, color, texture, thermal, and sensory analyses 24 h after production.

Protein requirement in the diet of Heros severus (Heckel, 1840): An Amazonian ornamental fish

Journal of the World Aquaculture Society, Volume 52, Issue 2, Page 482-495, April 2021., 2021
Abstract Two experiments to determine the crude protein (CP) requirement of Heros severus were performed. Five isocaloric (3,200 kcal kg−1 of digestible energy) diets containing five levels of CP (28, 32, 36, 40, and 44%) were evaluated. In the first, 75 fingerlings were distributed among 15 aquaria (30 L).
