It’s been a big opening week for the youngest generation of Island fishermen, with juniors and mini juniors holding their own against the grown-ups in the Martha’s Vineyard Striped Bass and Bluefish Derby.

One junior, Jack Balzarini, landed the derby’s first grand slam, and as of Thursday mini junior Mason Warburton held the top overall spot for false albacore. Not too shabby of a start.

And this Sunday, Sept. 21, kids will get more chances to shine, as the annual Kids Derby kicks off. From 6 to 9 a.m., the Steamship Authority wharf in Oak Bluffs is open to anyone between the ages of 4 and 14 (and their families), as they try their hand at bringing in one of the many fish swimming in the depths below.

The Kids Derby is a staple of the main event, and it’s where many first get hooked on the thrill of landing a fish. There’s no entry fee and no registration form — just show up with a rod in hand and stake out a spot. Bait is provided.

There are three age divisions in the derby, and winners receive new fishing gear. There is also a special trophy for the largest scup caught. All participants receive a free T-shirt.

Fish on!
