Tagal is a Kadazandusan word which means prohibition. In this case, it means a certain section of the river would be managed by the local kampung community which is empowered to enforce the fisheries rulings to ensure the sustenance of the fish population. At the fisheries experimental site at Kg Babagon where fishing is strictly prohibited, the Pelian (official name of Kelah in Sabah) came back strongly from near-zero existence within a matter of two years. Hundreds of them, averaging about half a kilo each, were easily swimming in groups. However they could only be tackled on flies or fish pellets. The whole idea of Tagal was to allow the river some breathing spaces to recuperate herself. To make the Tagal system practical, a Tagal zone is divided into three sections, namely the Green Zone (where regular regulated fishing is carried out by the kampung folks for their daily consumption), there is an Orange Zone (where fishing is allowed several times a year) and the Red Zone (where fishing is totally prohibited). Each zone is about a kilometre long, To ensure its success, the no-fishing zones are strictly enforced and offenders are severely penalized by the kampong community or the native court. Today as many as 167 kampungs throughout Sabah have adopted the Tagal systems
