Marine biology and marine science have many avenues of research and there is always some type of research going on in this area. One of the growing concerns in marine science and biology is the issue of harmful algae blooms in the seas. Harmful algal blooms (HABs) are algal blooms that can cause massive fish kills, contamination of seafood with toxins, and/or ecological damage through the development of anoxia or habitat alteration. These blooms are known to cause many problems around the world. These HABs can have negative effects on society due to economic and health risks. Many researches believe that the presence of HABs is growing worldwide. Much research is currently underway on these creatures to learn more about their distribution, environmental impacts, and their effects on human health, but this research has been severely limited by critical gaps in knowledge about physiological, behavioral, and genetic aspects. characteristics of these things.

Algae, like land plants, capture the sun's energy and support the food web that leads to the formation of fish and shellfish. They range in size from tiny microscopic cells floating in the water column (phytoplankton) to large mats of visible macroalgae growing on bottom sediments. These algae can become harmful if their population increases or if they start producing some toxins. Their large populations can cause environmental problems, which include blocking sunlight on underwater plants and depleting oxygen in the water, which can lead to fish deaths. Large numbers of algae can also produce a lot of pollution (scum) and could interfere with the feeding of the various fish and organisms that live in the water. However, the most harmful effect that some of these toxic algae can have is on human health and body. These harmful algae are known to bloom in high concentrations in various seas around the world, causing many health problems for humans. Sometimes algae grow extremely quickly, or bloom, and accumulate in dense, visible areas near the surface of the water. Red Tide is a common name for a phenomenon in which some species of phytoplankton contain reddish pigments and bloom in such a way that the water appears to be colored red. Unfortunately, a small number of species produce potent neurotoxins that can be transferred through the food web where they affect and even kill higher life forms such as zooplankton, crustaceans, fish, birds, marine mammals and even humans that feed directly or indirectly on them. Scientists now prefer the term HAB to refer to the bloom phenomenon that contains toxins or causes adverse effects. Much research is underway to find out more about these HABs. A recent study, entitled A Molecular Basis for Differential Susceptibility and Accumulation of Paralytic Shellfish Poisoning Toxins in Commercial Bivalves (supported by grants from the Ecology and Oceanography of Harmful Algal Blooms (ECOHAB) program of NOAA and the National Institutes of Health (NIH)) has revealed the molecular basis for resistance and accumulation of paralytic mollusk toxins (PSTs) in soft-shelled clams. This is a big problem for the East and West coasts of the United States. Shellfish in the area consume the toxic algae bloom and the poison comes .
