The article reports on the decrease in fish prices in Istanbul's market stalls, with anchovy and horse mackerel being the cheapest. The prices have dropped significantly since the previous week, with anchovy now selling for 60-70 liras per kilo, down from 100 liras. The abundance of these small fish has replaced the plentiful bonito, leading to a shift in market demand. Fishermen expect further price drops in the coming days, attributing the current affordability to the end of the bonito season.
