Population parameters of the yellow-edged lyretail (Variola louti, Forsskål, 1775) in Sibolga Waters

The grouper is one of the coral fishery commodities with high economic value. One of the members of the Serranidae family is the yellow-edged lyretail (Variola louti). In Sibolga waters, this fish was caught by traps and handline. The exploitation of yellow-edged lyretail in Sibolga waters was carri...
