The movie is part of the notorious german "SchleFaZ" series. Thus, it was aired September 2022 on german TV station Tele5. ("SchleFaZ" is a german abbreviation, means "the worst films ever". In that series 2 hosts present the whole flick - and make fun of it throughout the movie)
Although the script asked for male sharks, the ones modeled are female (note underside dorsal fins).
They had to use females because the males kept getting lost; it seems they wouldn't ask for directions.
