Optimization of the protein requirement of Channa striata larvae fed graded levels of protein dietOA Marine
The aim of the present study was to evaluate the optimal dietary protein level and its effect on the survival rate, observed mortality, cannibalism rate, growth performance, and digestive and metabolic enzyme activity of Channa striata larvae. A total of 4,950 larvae with an average initial weight of 1.5 ± 0.00 mg and an average total length of 0.6 ± 0.01 cm were stocked at 550 larvae in triplicate and fed with isolipidic diet...
This study examined the effect of dietary selenium (Se) fortification on growth efficiency, antioxidant status, and liver gene expression in juvenile pangasius catfish. Sodium selenite was incorporated into a basal diet at incremental levels of 0–2.0 mg Se/kg. This resulted in final Se concentrations of 0.63, 0.85, 1.15, 1.68, 2.10, and 2.65 mg Se/kg, respectively. A total of 15 fish, with an average individual weight of 5.6 ±...
Geodiversity is under threat from both anthropogenic activities and environmental change which therefore requires active management in the form of geoconservation to minimise future damage. As research on the role of geodiversity on ecosystem service (ES) provision has been limited, there is a need to improve our understanding of which aspects are most important to providing ES to better inform approaches to its conservation....
Stochasticity is a core component of ecology, as it underlies key processes that structure and create variability in nature. Despite its fundamental importance in ecological systems, the concept is often treated as synonymous with unpredictability in community ecology, and studies tend to focus on single forms of stochasticity rather than taking a more holistic view. This has led to multiple narratives for how stochasticity me...
