“…In addition to recovering the nutrients, the living microalgal cells added into the fish rearing tank can serve as a 'bio-pump' to increase the content of dissolved oxygen (DO). 3 The study by Huo et al (2020) revealed that, with the addition of microalgae, the content of DO can be maintained at a higher level. 16 The aerobic conditions can promote the growth of some aerobic bacteria, particularly nitrifying bacteria, creating a better environment for aquatic animals.…”

The application of microalgae biotechnology, which can recover nutrients from wastewater, improve water quality, and feed some aquatic animals, is becoming an emerging trend in the development of eco-friendly aquaculture. Previous studies explored a variety of models to support the use of microalgae in aquaculture practice, verifying the feasibility and advantages of microalgae-based aquaculture. However, a couple of bottlenecks and problems jeopardizing the application of microalgae biotechnology in aquaculture are discovered in the research and industrial practice. This work, hence, summarizes the research progress and the current opinions relating with the microalgae-based aquaculture and proposes some critical thoughts about the bottlenecks challenging its industrial implementation.

Aquaculture is an important industry providing high‐quality animal protein to humans, but it brings serious environmental pollutions, such as eutrophication of water bodies and the abuse of antibiotics. Microalgae cultivation, which can recover nutrients, release oxygen and yield value‐added biomass, has been studied intensively as a promising biotechnology for aquaculture wastewater treatment and fish diet production. Herein, we introduce a novel concept of applying microalgae biotechnology in aquaculture by integrating wastewater remediation, biomass harvesting and aquatic animals rearing systems. We review recent progress in aspects of value‐added algal species screening, algae cultivation systems design, nutrient recovery by algal–bacterial interactions, and biomass harvesting technologies. Finally, we discuss some problems, including bacterial contamination, unfavorable conditions in effluent and lack of technological assessment, which may hinder the application of microalgae biotechnology. It is expected that this paper could attract researchers' and technicians' attention to the microalgae‐based pollution control and promote the development of ecofriendly aquaculture. © 2020 Society of Chemical Industry

Astaxanthin: A super antioxidant from microalgae and its therapeutic potential

Astaxanthin is a ketocarotenoid, super antioxidant molecule. It has higher antioxidant activity than a range of carotenoids, thus has applications in cosmetics, aquaculture, nutraceuticals, therapeutics, and pharmaceuticals.Naturally, it is derived from Haematococcus pluvialis via a one-stage process or two-stage process. Natural astaxanthin significantly reduces oxidative and free-radical stress as compared to synthetic astaxanthin. The present review summarizes all the aspects of astaxanthin, including its structure, chemistry, bioavailability, and current production technology. Also, this paper gives a detailed mechanism for the potential role of astaxanthin as nutraceuticals for cardiovascular disease prevention, skin protection, antidiabetic and anticancer, cosmetic ingredient, natural food colorant, and feed supplement in poultry and aquaculture. Astaxanthin is one of the high-valued microalgae products of the future. However, due to some risks involved or not having adequate research in terms of long-term consumption, it is still yet to be explored by food industries. Although the cost of naturally derived astaxanthin is high, it accounts for only a 1% share in total astaxanthin available in the global market. Therefore, scientists are looking for ways to cut down the cost of natural astaxanthin to be made available to consumers.
