Raymond Frank Wood, 32, of Queensland, and Trent Alan Woodall, 33, were also found guilty of  taking undersized lobster and using prohibited equipment to take rock lobster on January 14 this year.

Joshua Guy Clements was fined $300 for refusing to give his name and address, and giving a false name and address when questioned by fisheries officers on January 14.

William Sinnott, for Fisheries Victoria, said Wood and Woodall had been found with eight lobsters when the limit for recreational lobster catches was two a day.

Five of the eight lobsters were less than the minimum size that could be harvested, Mr Sinnott said.

Wood had admitted to taking three to four of the lobsters and Woodall had said he had taken the others. 

Wood had said he did not know what size the lobsters were and had thought the daily limit for recreational lobster catches was four a day.

Woodall had said he did not have anything to measure the size of the lobsters, Mr Sinnott said.

The court also heard that Woodall used a spear to take the crayfish when recreational fishers were required to harvest them by hand.

Mr Sinnott said Clements had told fisheries officers he was not involved with the other two men and had at first refused to stop and provide his real name and address when requested by the officers.

He had later provided his real name and address after police were called.

Mr Pat McComish, for Clements, said his client admitted to behaving stupidly at the time.

Clements had not given his name and address because he was not aware of the seriousness of the offences, Mr McComish said.

Magistrate Ian von Einem said Wood and Woodall should have made proper inquiries about the regulations for the recreational harvest of rock lobsters.

He rejected the requests from the two to regain their wetsuits that had been seized by fisheries officers but said he would reduce the fines in view of the forfeited wetsuits.
