In recent years, suboptimal environmental conditions have been frequently reported to negatively impact on aquaculture organisms. Salinity is an important environmental factor, and its fluctuation will affect survival, growth and, potentially, the meat quality of the organisms with narrow salt tolerance cultured in coastal and inner bay. The aim of the study was to ascertain and report the influence of sub‐low salinity (28 and 30) on the production traits and nutrient composition of the Pacific abalone Haliotis discus hannai (DD), and two of its hybrids (DF and SD). In view of this, 360 abalones were subjected to four salinity levels (28, 30, 32 and 34) for ninety days. The data showed that the weight gain and the specific growth rates in wet weight between the groups followed the trend of DF > SD > DD. DF recorded the highest meat yield, which was significantly higher than SD and DD (p < .05). The sub‐low salinities tested did not influence moisture content, crude protein, total lipid and total carbohydrate (p > .05). Whilst lipid levels were fairly higher in SD and DF than in DD, at sub‐low salinities, the opposite was true for carbohydrate content. Total minerals (ash), however, were influenced by salinity (p < .05). Individuals reared at 28 significantly differed from those of the other three treatments, but there was no significant difference between the groups (p > .05). Further analysis showed sodium and potassium as the predominant minerals—with a higher concentration of sodium at higher salinities, though no significant difference was found between individuals treated at 30, 32 and 34. Zinc was the only mineral not affected by salinity (p > .05), and the accumulation of discrete minerals by the species significantly differed from one mineral to the other and proved to be species‐specific. Notwithstanding, SD demonstrated superior content of most essential minerals over DF and DD. The results in this paper infer that the Pacific abalone and its hybrids could maintain good meat quality and survival under a range of 28–34 of salinity, promoting the growth of cultured abalone under the sub‐low salinity of 28.

Power consumption by telecommunication industrial loads is increasing day by day as the user of this technology is on the rise. Telecommunication base station towers are consuming twice or more energy than in the past for the implementation of high-capacity devices to serve more users. As a result, there is an extra power requirement for the telecommunication loads which can cause an inadequate power supply and lead to the implementation of additional infrastructure in the power industry. Powering these resources will demand more energy production and introduce various types of new problems in the grid network. The impact analysis of the effect of this extra demand in a regular network system has great interest. Also, most of the base stations are equipped with a backup battery as an essential need in third-world country grids and contribute a portion of the load demand of a power distribution system. All telecommunication industrial towers are considered under industrial load and have a special industrial tariff imposed by the power supply authority. This paper utilizes the optimal power flow method to calculate a proposed schedule base demand-side management system adopted to shift the pattern of charging batteries along with temperature control loads in the telecommunication towers and outlines an analytical study on a test power grid network. To determine the best electricity flow, generation, and locational marginal prices for each hour, an algorithm is created. Following careful evaluation of the appliance status, the constraint and condition are then applied to the load curve. This study indicates there is energy-saving and both supplier and consumer sides can minimize the operation cost.This is an Open Access article distributed under the terms of the Creative Commons Attribution License (http://creativecommons.org/licenses/by/4.0/), which permits unrestricted use, distribution, and reproduction in any medium provided the original work is properly cited.
