Global consequences of dam-induced river fragmentation on diadromous migrants: a systematic review and meta-analysis. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The global proliferation of dams has altered flow and sediment regimes in rivers, presenting a major threat to freshwater biodiversity. Diadromous species, such as fishes, decapod crustaceans and gastropods, are particularly susceptible to fragmentation because dams obstruct their breeding migrations between coastal waters and rivers. Although

Growth performance and gene expression of FAS, CPT1, G6P, and HK in juveniles of the freshwater prawn, Macrobrachium acanthurus, fed diets with different levels of protein, lipids, and carbohydrates

Journal of the World Aquaculture Society, Volume 54, Issue 6, Page 1644-1658, December 2023., 2023
Abstract A feeding trial with Macrobrachium acanthurus juveniles was performed to determine growth performance and utilization of diets varying in protein, lipid, and carbohydrate level. Twelve diets were formulated with three levels of protein (P) and supplemented with different proportions of lipids (L) and carbohydrates (C): P30‐L20‐C8, P30‐L15‐C19,

Welfare of Decapod Crustaceans with Special Emphasis on Stress Physiology

Aquaculture Research, Volume 2023, Issue 1, 2023., 2023
Despite the growing concern on animal welfare in crustacean farming, both from legislative bodies as well as the common public, studies on welfare are limited and transfer to routine farming is missing. While biocertification schemes such as the Aquaculture Stewardship Council (ASC) involve a welfare dimension, these dimensions cannot be communicated ...

Gill and haematological alterations in Macrobrachium amazonicum adults in acute exposure to ammonia and nitrite isolated and combined

Aquaculture, Fish and Fisheries, Volume 2, Issue 5, Page 414-424, October 2022., 2022
Total ammonia and nitrite combined generated antagonism. Less severe damage occurred on gills exposed to ammonia and nitrite. High THC are found in the highest concentrations of the nitrogen compounds. Abstract The present study evaluated the isolated and combined effect of total ammonia and nitrite on Macrobrachium amazonicum adults through the median
