HALIFAX -- A Cape Breton fisherman convicted of manslaughter in the death of another fisherman is seeking an appeal of his 14-year sentence.

Joseph James Landry was found guilty in November of shooting Phillip Boudreau in the leg, ramming his boat three times and hooking him with a fishing gaff before dumping his body at sea.

Landry was granted 2 1/2 years credit for time served in custody awaiting trial, meaning he is serving 11 1/2 years.

At trial, a jury concluded that Boudreau, whose body has yet to be found, was the victim of a sustained attack at the mouth of the harbour near Petit-de-Grat on June 1, 2013.

Landry's notice of appeal says the grounds for such an action include the trial judge's imposition of a harsh and excessive sentence, given the circumstances of the offence.

The document also suggests the trial made findings of fact not consistent with the jury's verdict.

The notice filed Feb. 11 says the Nova Scotia Court of Appeal should reduce Landry's sentence to seven years and cut his actual prison time by another 901 days to account for pre-sentence custody.

The document says Landry wants to present a written argument to the court at a later date.
