Mayor Benjamin S. Lim of Dagupan City is inclined to adopt the rope frame cage technology to take the place of fishpens after discussing with Bureau of Fisheries and Aquatic Resources Region 1 Director Nestor D. Domenden recently aabout environment-friendly fish structures suited for the rivers here. Domenden, in his media presentation, recommended to Lim the rope frame cage technology as a replacement to the fishpen, which causes siltation in the river.
“Ito po yung bagong modification ng materyales na ginagamit sa paggawa ng fish cage. Hindi katulad ng bakal at high density pvc pipe na kung na-expose sa malalaking alon ay napuputol at napipilipit,” said Domenden.
He said that the technology is very flexible. “Pinapalutang lang floats na nakadikit sa angkla na connected sa rope. This is highly recommended sa malalalim na lugar ng ilog o dagat at malalakas ang current lalo na sa mga ilog na may more than 3 meters deep upang magkaroon pa ng allowance or clearance mula doon sa bottom ng net doon sa surface ng river bottom,” explained Domenden.
Domenden said that the technology costs 45.000 pesos, but in comparison, the cage is far better because it is not an agent of siltation.
City Agriculture Officer Emma Molina, who was also present in the meeting, said that the city is now considering the new technology as an option to ensure the rivers’ sustainability.
“We are now scheduled to conduct a site validation and reconnaissance on January 25 in the areas which used to be the spot for fish cages or ‘bilayan’,” said Molina. (CIO – Joseph C. Bacani)
