Kona-based Cyanotech Corp. said today record sales of microalgae products helped boost its net income by 22 percent in the quarter ending June 30 compared with the same three-month period a year earlier.

The company’s shares jumped 8 percent to close at $3.95 on the news.

The company reported net income of $486,000, or 9 cents a share in the latest quarter, up from $399,000, or 7 cents a share for the same quarter a year earlier.

The earnings came on record sales of $5.95 million in the April-to-June quarter compared with sales of $2.09 million a year earlier.
