Stocking broilers at a high density has been a strategy to optimize the area of the cage and hence increase the efficiency of broiler production. If the environmental (microclimate) conditions and rearing management are not properly managed, stocking broilers at a high density may, however, result in stressful…

Background The characterization of colonization and dynamic changes related to gut microorganisms might be vital, as it presents an opportunity to quantify the co-variation between stocking densities and gut microbiome of dynamic distribution. The objective of this study was to determine the stocking density on…

'Aziz ur Rahman Muhammad'] Broiler production in semi-arid tropics must contend with high levels of heat stress, which have implications on stocking density, bird welfare, and profitability. Under these conditions, optimal stocking densities are likely to be lower than expected, thus must be experimentally determined.…

Simple Summary Recirculating aquaculture systems (RASs) have gradually become a highly recommended aquaculture mode due to their environmental friendliness. However, due to their high factory and equipment investments and high electricity consumption, they usually require the farming objects to have high economic value…

Saraiva et al. (1) argue that “Legislation directly limiting stocking density is likely to be unworkable…” (p. 4). We disagree as there are already relevant, proven track records for using stocking densities in aquatic- and terrestrial-farmed animal welfare legislation. For example, legislation protecting broiler…

Calanoid copepod Acartia species are major live feeds for the early stages of economically important marine fish in hatcheries in Southeast Asian countries. However, rearing Acartia copepods at high densities to increase productivity remains a major challenge. To address the issue, we conducted two experiments on 1)…

Simple Summary Stocking density is a key factor for animal welfare in aquaculture, as it can cause stress in fish. However, a low stocking density could reduce feed competition among cultured fish, resulting in a decrease in feed intake and, consequently, productivity. To assess both animal welfare and productivity in…

'Jia Liu' 'Tao Huang' 'Jing Bo Liu' 'Jin Song Pi' 'Hao Zhang'] Objective The rice-duck-crayfish (RDC) coculture system, an ecologically efficient breeding strategy that accommodates natural behavior of ducks and improves their welfare. The optimal stocking density and its impact on duck health in this system remains…

'Taufiquar Khan'] Abstract. We propose, analyze and test two novel fully discrete decoupled linearized algorithms for a nonlinearly coupled reaction-diffusion N-species competition model with harvesting or stocking effort. The time-stepping algorithms are first and second order accurate in time and optimally accurate…

The past decades have witnessed efforts to unveil ecological risks associated with massive releases of captive-bred individuals (“stock enhancement”). Still, we may underestimate the negative impact because current schemes rarely consider the consequences of stock enhancement for the whole ecological community. Here…

Chronic stress poses a challenge to aquaculture, with cortisol and glucose traditionally used as stress markers. Recent doubts about the reliability of scale cortisol as a chronic stress determinant have surfaced due to its role in calcium homeostasis. While cortisol affects gene expression in stress responses, its…

Exploring Decoupled Algorithms and Analysis Authors: ['Mayesha Sharmim Tisha' 'Md. Kamrujjaman' 'Muhammad Mohebujjaman' 'Taufiquar Khan'] Abstract. We propose a time-dependent Advection Reaction Diffusion (ARD) N-species competition model to investigate the Stocking and Harvesting (SH) effect on population dynamics.…

Many small pelagic fishes obligately form schools; some of these schools attain a remarkable size. Although the school is a fundamental and important ecological unit and is the site of biological interactions such as competition and predation, information on schooling processes in the field remains scarce. Here, we…

Resilient supply chains are critical, especially for Original Equipment Manufacturers (OEMs) that power today's digital economy. Safety Stock dimensioning—the computation of the appropriate safety stock quantity—is one of several mechanisms to ensure supply chain resiliency, as it protects the supply chain against…

Understanding how management alters species’ biodiversity and interactions is critical for sustainable agriculture. This can be especially important for rangelands, grasslands used for livestock grazing that cover 30% of land worldwide. In rangelands, ranchers need to maximize livestock production while supporting…

Wood pulp fibers can be hot-pressed to form binder-less high-density fiber network sheets of improved mechanical properties, competing with polymer matrix biocomposites. We have investigated hot-pressing, microstructure, and mechanical properties of eco-friendly and low energy-demand chemi-thermomechanical (CTMP) wood…

A large collection of element-wise planar densities for compounds obtained from the Materials Project is calculated using brute force computational geometry methods. We demonstrate that the element-wise max lattice plane densities can be useful as machine learning features. The methods described here are implemented in…

Livestock agriculture generally operates as a linear economy, consuming large quantities of nonrenewable energy and nutrients while generating waste that often pollutes the environment. In this work, we propose approaches to help mitigate nutrient pollution via the development of cyanobacteria-based processes that…

Ice nucleating substances (INSs) influence the properties and frequencies of ice and mixed-phase clouds in the atmosphere, and hence, climate and the hydrological cycle. INSs can be classified as inorganic (e.g., mineral dust, volcanic ash) or organic (e.g., bacterial cells, cell-free proteins). While the properties of…
