The exercise follows recent mysterious losses of tilapia in fish farms along the Volta Lake. The Asutuare area in the Shai Osudoku District recorded one of the largest viral outbreaks in October 2018.

The vaccination is done via an injection in the abdomen of the fingerlings.

The Minister of Fisheries and Aquaculture Development, Mrs Elizabeth Afoley Quaye, told journalists at Forsell Farms, a fish farm at Kpotame, near Sogakope, last Monday that the exercise had become necessary due to how critical the sector was to the economy.

She said the mass immunisation exercise was being carried out by the ministry and the Fisheries Commission on fish farms along the Volta Lake to address the recent fish deaths, since the virus and organisms that caused the outbreak were found on those farms.

She commended the Ministry of Finance for making available GH¢2 million out of the estimated GH¢12 million needed for the exercise over a three-year period, and was optimistic that more funds would be made ready for use in due course.

"We have been trying to do this for some time now and now that funds have been made available, we intend to cover all fish farms on the Volta Lake," she said.

Mrs Quaye was hopeful that the “Finance Ministry will make more funds available to sustain the mass immunisation”.

Strategy

Ten vaccinators are carrying out the exercise with each expected to vaccinate 1,500 fish a day, totalling 150,000 fish vaccinated in a day.

Mrs Quaye said it was the ministry’s expectation that the exercise would cover a large number of farms in order to stop fish dying, adding that the state intervened to ensure there was no further outbreak.

Livelihoods

According to her, outbreaks such as that which occurred could wipe out farms if not handled well, and would lead to economic and social losses as several people could lose their livelihoods.

She disclosed that already, 50 fish farms had folded up with accompanying job losses due to the outbreak.

Infections

The Head of Fish Health Unit of the Ministry of Fisheries and Aquaculture Development, Dr Peter Ziddah, who is leading the team of technical officers for the immunisation exercise, said there had been an upsurge of infections from 2014, including streptococcal 1A and B, which had been dealt with.

He said towards the end of 2018, the infectious spleen and kidney virus was also noticed, hence the move by the ministry to trigger the immunisation exercise.

Dr Ziddah said fish weighing 0.3 grammes upwards were immunised with the ‘irido vaccine’, adding that the vaccination had no public health issues since the disease could not be transferred from fish to humans.

He, therefore, encouraged the public to continue patronising tilapia.

Commendation

The Managing Director of Forsell Farms, Mr Evans Kwadzo Danso, commended the government and the ministry for the intervention.

He said the outbreak of the diseases had had a number of fish farms along the Volta Lake under stress with many farmers at a loss as to what to do since the vaccines were expensive.
