A Tasmanian abalone diver who conspired with other divers to create false details on catches has been given a six month suspended jail term.

Peter Joachim Kossman pleaded guilty to four charges relating to false records and statements between March 2000 and November 2002.

The Supreme Court in Hobart heard the 52 year old allowed other divers to fish areas around the Furneaux group of islands where he held exclusive rights.

Abalone worth $630,000 was taken by those divers over the 20-month period, with Kossman falsifying the catches as his own.

In sentencing Justice Alan Blow took into account the fact Kossman’s crimes had no impact on the sustainability of the abalone fishery.

But the judge said the offending was serious because it related to large quantities of abalone.
