The use of pesticides in agriculture only functions as much as 90%. The rest has polluted the surrounding environment, especially fish. Organophosphates are active neurotoxins. The organophosphate does not require any other conversion to inhibit the acetylcholinesterase enzyme. Organophosphates have the ability inhibit the action of the acetylcholinesterase (AChE) enzyme which results in disruption of acetylcholine when it provides stimulation impulses from pre-synapse to post-synapse (neurotransmitter), this results in impaired muscle work. So that the work of the undirected muscles that can cause symptoms of poisoning that affect the work of the whole body. This study aims to know the effect of sublethal toxicity of organophosphate pesticides on development organ and the survival rate of silver rasbora larvae, and to determine the exposure of organophosphate pesticides that can affect development organ and the survival rate of larvae. The research method was an experiment with a Completely Randomized Design as an experimental design. The treatments used were different organophosphate concentrations, that is 0, 0.5, 1, 1.5, and 2 ppm. Each treatment was repeated four times. The main parameters observed were the development organ of larvae, egg yolk absorption rate, abnormality larvae. The results showed that organophosphate pesticide exposure of 0.5-2 ppm could affect the development of the organ, survival rate, and abnormality silver rasbora larvae. Exposure to organophosphate pesticides can also increase the absorption rate of egg yolks in larvae. Exposure dosage to organophosphate pesticides is directly proportional to the percentage of larva abnormalities and inversely proportional to the value of survival rate larva.
