Exploration of clay minerals in mitigating fish-killing algal blooms
, 2017 Fish-killing algal blooms increasingly threaten global aquaculture operations through the production of a wide variety of potent fish-killing toxins (ichthyotoxins). Effective mitigation strategies are therefore much needed. This thesis work explored the

Proceedings of the Nigerian Academy of Science, 2020 Plant-based ichthyotoxins are increasingly used for commercial fishing activities in many countries all over the world. This study investigated the acute and sub-acute effects of the aqueous extracts of some plant-based ichthyotoxins, commonly used in Nigeria, on Clarias gariepinus.

Harmful AlgaeIn May-June 2019, the microalga Chrysochromulina leadbeateri caused a massive fish-killing event in several fjords in Northern Norway, resulting in the largest direct impact ever on aquaculture in northern Europe due to toxic algae. Motivated by the fact that no algal toxins have previously been described from C.

Isolation and characterization of toxins from the phytoflagellate Prymnesium parvum
, 1996 Toxic strains of Prymnesium parvum were isolated from fish ponds with blooms of a toxigenic flagellate P. parvum and high fish mortality. The pure culture was successfully achieved in laboratory. Culture of P. parvum grew well in medium of artificial sea
