Kivukoni is the biggest fish market in Tanzania's main city, Dar es Salaam. Fish are an important part of the diet for those Tanzanians who live near the country's long coast and many lakes. However, fishermen complain that huge, modern boats from Europe and Asia are taking most of the best fish from their country's waters.

As part of the deal for its boats to fish in Tanzanian waters, Japan built the modern market, which embodies the hustle of the city, and employs about 3,000 people - including ice salesmen, boat repairmen, wood suppliers and traders.

Dozens of youngsters work on the boats, going out to sea in the early hours, and later carting the fish to the traders. In coastal areas, fish is much cheaper than meat but inland and away from the lakes where many people are animal herders, meat is cheaper and fish is seen as a delicacy.

Rajabu Mungi, 24, finished school five years ago and came to work on the boats. He earns about 8,000 shillings ($5; £3) each day.

After the early-morning trading is done, the workers move to the other side of the market for a well-earned meal.

Ally Iddi, 32, is among those who cook up the fish. He has been in the job for 17 years and brings up three children on his wage.

Many of the traders and cooks sleep near the market in shelters made from tarpaulin and corrugated metal. They are trying to save money to buy land in their home villages.
