- •
P-CTX-1 at sub-ppb levels adversely affected the physiology and behaviour of larval marine medaka.
- •
The heartbeat rate, locomotor activity and survivability of larval marine medaka were significantly reduced by P-CTX-1.
- •
P-CTX-1 exposed larval marine medaka possessed reduced, delayed or no response to external stimuli.
- •
P-CTX-1 affected the fitness of larval marine medaka to survive.
- •
P-CTX-1 exposed larval fishes may conceivably become more susceptible to natural selection pressure such as predation.
