“…As variations in MCs contamination among species and months were observed, the study recommended to adjust the legal fishing seasons or select certain species to harvest for the sake of safe seafood. The same recommendation was again highlighted in another recently published paper by the same author; however, the samples were collected in 2009-2010 [136]. By contrast, D. Zhang et al reported that the consumption of silver carp fish from any lake of eight eutrophic Chinese lakes, located along the Yangtze River, is safe as the estimated daily intake (0.002 to 0.007 µg/kg day) was much lower the provisional TDI [143].…”

“…Although a considerable number of published papers are from China, in comparison to other Asian developing countries, most of these papers surveyed only two lakes (Taihu and Chaohu) (Table 3). Seasonal changes and distribution patterns in MCs (-LR, -YR and -RR) concentrations were studied in commonly consumed Chinese shrimps (Palaemon modestus and Macrobrachium nipponensis), silver carp (Hypophthalmichthys molitrix), bighead carp (Aristichthys nobilis), four freshwater bivalves, and mussels (Corbicula fluminea) collected from Lake Taihu and Lake Chaohu [51,[132][133][134][135][136][137]. All these studies have reported considerable seasonal variations (from June to December of the studying years) and correlation with MCs with cyanobacterial bloom.…”

Cyanotoxins have gained global public interest due to their potential to bioaccumulate in food, which threatens human health. Bloom formation is usually enhanced under Mediterranean, subtropical and tropical climates which are the dominant climate types in developing countries. In this context, we present an up-to-date overview of cyanotoxins (types, toxic effects, analysis, occurrence, and mitigation) with a special focus on their contamination in (sea)food from all the developing countries in Africa, Asia, and Latin America as this has received less attention. A total of 65 publications have been found (from 2000 until October 2021) reporting the contamination by one or more cyanotoxins in seafood and edible plants (five papers). Only Brazil and China conducted more research on cyanotoxin contamination in food in comparison to other countries. The majority of research focused on the detection of microcystins using different analytical methods. The detected levels mostly surpassed the provisional tolerable daily intake limit set by the World Health Organization, indicating a real risk to the exposed population. Assessment of cyanotoxin contamination in foods from developing countries still requires further investigations by conducting more survey studies, especially the simultaneous detection of multiple categories of cyanotoxins in food.

“…Some common MC congeners include MC-LR, MC-RR, MC-YR, and MC-LA [92]. Human exposure to MCs commonly occurs through the consumption of drinking water, contaminated fish, shellfish, vegetables, and algal dietary supplements and through recreational activities near bodies of water affected by MC-producing cyanobacterial HABs [93][94][95]. MC-LR is the most abundant and extensively studied MC.…”

The effects of global warming are not limited to rising global temperatures and have set in motion a complex chain of events contributing to climate change. A consequence of global warming and the resultant climate change is the rise in cyanobacterial harmful algal blooms (cyano-HABs) across the world, which pose a threat to public health, aquatic biodiversity, and the livelihood of communities that depend on these water systems, such as farmers and fishers. An increase in cyano-HABs and their intensity is associated with an increase in the leakage of cyanotoxins. Microcystins (MCs) are hepatotoxins produced by some cyanobacterial species, and their organ toxicology has been extensively studied. Recent mouse studies suggest that MCs can induce gut resistome changes. Opportunistic pathogens such as Vibrios are abundantly found in the same habitat as phytoplankton, such as cyanobacteria. Further, MCs can complicate human disorders such as heat stress, cardiovascular diseases, type II diabetes, and non-alcoholic fatty liver disease. Firstly, this review describes how climate change mediates the rise in cyanobacterial harmful algal blooms in freshwater, causing increased levels of MCs. In the later sections, we aim to untangle the ways in which MCs can impact various public health concerns, either solely or in combination with other factors resulting from climate change. In conclusion, this review helps researchers understand the multiple challenges brought forth by a changing climate and the complex relationships between microcystin, Vibrios, and various environmental factors and their effect on human health and disease.

“…Biomanipulation with silver carp is only efficient at eliminating the algal blooms that cannot be eliminated by herbivorous zooplankton [58]. Isotopic techniques estimate around 45% assimilation rate of Microcystis aeruginosa in silver carp [59]. Similarly, silver carp's growth and ingestion were noted while fed with toxic species of Microcystis in controlled environment [60].…”

In classical biomanipulation, piscivores fish is introduced to a water body which fed on planktivorous fish and causes an increase in the numbers of zooplankton and zooplankton by feeding on phytoplankton roots to reduction in algal blooms. In contrast, during non-classical biomanipulation piscivores fish is removed from the water body and planktivorous fish is introduced which fed on all kinds of plankton and led to improving the water quality parameters by reducing nuisance algae. Here, we examine the management of water quality parameters through non-classical biomanipulation by identifying problems and extract recommendations. Preference is given to non-classical biomanipulation due to certain hindrances with traditional biomanipulation such as planktivorous fish removal, increase in numbers of macrophyte and decrease in phosphorous (external and internal), respectively. In fact, non-classical biomanipulation can also be used to control algal blooms in tropical, highly productive lakes, where reduction in nutrient concentration is almost impossible. In spite of overlapping prey and predator spaces in closed environments, such as in tanks and ponds, similar results of non-classical biomanipulation were also obtained in lake ecosystems as well. Non-classical biomanipulation changed the community composition of phytoplankton at the start of trial in both enclosed water bodies and lakes. In our review of 30 studies, 63% of studies demonstrated successful control of phytoplankton with non-classical biomanipulation. Microcystis blooms were controlled efficiently by two planktivorous fish, bighead carp (Hypophthalmichthys nobilis) and silver carp (Hypophthalmichthys molitrix), in Lakes Qiandaohu and Donghu, respectively. Eutrophic waters that lack sufficient concentration of macrozooplankton can be effectively managed through planktivorous fishes, such as bighead and silver carp. Non-classical biomanipulation is confirmed as an effective tool for the control of those nuisance algal blooms that cannot be controlled efficiently by large bodied herbivorous zooplankton while ineffective with blooms of nanophytoplankton species.
