Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Because of the migration of salmon, the total number of salmon in river Trout has increased by ten times the number initially in the river. If there were 500 salmons initially, calculate the total number of fish in the river now.

### Response:
 Ikiwa idadi ya samoni katika mto imeongezeka mara kumi ya idadi ya awali, basi 500*10 = <<500*10=5000>>5000 samoni wapya wamehamia mto huo.
Kwa sasa, kuna samoni 5000+500 = <<5000+500=5500>>5500 katika mto Trout.
