A brief overview of the issues faced by Harmful Algal Blooms along Johor straits

Urbanization of coastal areas worldwide has increased due to an increase in the global population. The production of sustainable aquaculture is greatly impacted by a surge of this urbanization. In certain countries, particularly for individuals with more limited space in metropolitan areas, such as along Johor's coastal area, aquaculture might well be a good strategy to maintain food availability (continuous production plus high-quality meals). Consequently, the adoption of aquaculture along the Johor's coastal area has lead to Harmful Algal Blooms (HAB). This paper examines the evolution of the aquaculture industry of Malaysian Johor coastal areas in relation to HABs. In addition to HABs, the aforementioned metropolitan regions confront diverse economic and geographical obstacles when attempting to increase their aquaculture production sustainably. Those problems are therefore addressed using a variety of operations as well as surveillance techniques in this brief overview. Lockdowns and border prohibitions caused by the continuous COVID-19 infection have had a global impact. These logistical difficulties in the seafood industry have increased dependency on imported supplies. It is suggested that international decision- making, supervision, and knowledge exchange can successfully solve the challenges urbanized areas have in ensuring sustainable food security through the evolution within the aquaculture sector.

Covid-19 Effect on Community Mobility and Stock Market of Malaysia

Physical distancing is believed to contain the spread of COVID-19 virus. With data provided by COVID-19 Community Mobility Reports from Google, this study examines the mobility patterns at different stages of Movement Control Order (MCO) and investigates whether lower mobility reduces the number of new cases, death cases, and recovery rate. This research also covers the time spent in places such as i) retail and recreation, ii) grocery and pharmacy, iii) parks, iv) transit stations, v) the workplace, and vi) residential areas. As each of these types of places has distinct epidemiological characteristics, they may spread transmission differently. This study also correlates the stock market with mobility patterns of Malaysians in order to evaluate the effectiveness of lockdowns on COVID-19 incidents and its impact on the stock market, in this case;Kuala Lumpur Composite Index (KLCI). Findings of this study highlight the effects of pandemic COVID-19 on stock market daily performance by utilizing prospect and uncertainty theory in predicting the short-term impacts of the epidemic.
