Revenue increased by 22% to £4.12mln with second half sales up by 45% year-on-year, having benefited from £1.5mln of capital raised in a placing in June.
The group also raised £500,000 in a placing in the second half to fund expansion of its store network.
Gross profit rose 21% to £1.88mln, pre-tax profit before exceptional items lifted 3% to £305,000 but reported pre-tax profit was £5,700 against £295,000 last time.
In December, the primarily Northern England-based group bought Cotswold Angling near Swindon, which it said would give it a presence in the south.
It also signed leases on three shops, in Hull, Birmingham and Crewe, which opened in the first quarter of this year.
Chief executive Steve Gross said: "We remain very optimistic about prospects as we look to continue to develop the business."
