In Hiwasa fishery, the boat is equipped with the holy trinity of off shore fishing - sonar, water spray and live anchovy. By contrast here in Kohchi, fishing is done in a more primitive fashion - you have none of them.

To catch them on fly, you often have to take turns - one to throw poppers and pull the school up close while another prepare his or her cast at the right moment.

A nice fish that got teased up with Sayuri's popper nailed down my fly at a point blank range. A solid strip strike was all it needed before rocketing off into the center of the Pacific!

Mahi Mahi fishing can be a hit and miss. One day they are biting at anything that comes in sight, the next day not a soul to be seen. Such is common in the earlier part of the season (though that's when you encounter trophy fish) but as the season heats up, say mid July in case of Kohchi bay, you are likely to see big schoole of them.

What you need is a calm sunny day - which was the case on our outing in late July 2010.

The day's hottest fly was this large anchovy imitation 13cm in length. But don't take this as the general rule - the next day they can be only after 3cm micro bait.

SW fyfishing is still at its incubation stage and no captain really understand what we need. But doing everything for yourself certainly has its own element of fun - and a sense of accomplishment.

The action was hot from the outset. Sayuri's first fish of the day was a respectable buck of 118cm in length, while I too managed to boat a feisty young lad soon thereafter.

Unlike another popular fishery ''Hiwasa'' a few hours' drive east, fishing here in Tei is done much closer to the coast. In short half an hour's ride out, you notice the captain slow down the boat, and the game is on.

Big schools of Mahi Mahi swim up our coast riding on 'Kuroshio' warm current every year from late spring to summer. Keen fishermen travel down to Okinawa to intercept them in spring while many more simply wait for their arrival in the mainland later in the season. One of the popular summer fisheries is Kochi bay, in the south of Shikoku island.

The boat we chartered was Hisyo, captained by one of Kohchi bay's old hand, Nanbu-san. He works tirelessly, taking us to one Uke after another. Although you'd only spend 5-10minutes at one Uke, there are many hundreds of them chained up all the way to the horizon. A hard work for the captain and even for a determined fisherman!!

Fishing in Kohchi bay is mostly done around ''Uke'' - a traditional fish attracting device made of dried bamboo poles roped together. At the beginning of every season professional fishermen float them in the bay on the edge of the Kuroshio current.

The most numerous tenants are Mahi Mahi, locally called Manriki. They used to net these magnificent fish by the tons but their flesh is easy to deteriorate thus have limited commercial value ($1 a kilo). They discovered recently they worth thousand times more in the hands of sports fishermen, and started taking us out for about $400 a day. A nice deal for the both parties.
