Effectiveness and Impact of Artificial Reef Project in Tigbauan, Iloilo, Philippines: A case study

Abstract

Artificial reefs (ARs) are one of the popular and important management approaches to enhance fishery production, especially in overfishing areas. In this paper, a case study was conducted to determine the effectiveness and impact of the AR project in Tigbauan, Iloilo, Philippines, through a qualitative field survey research approach. Findings revealed that while other fishers reported that AR improved longline catch, gill net – a major fishing gear used in the area, did not experience any catch changes; rather, it sometimes entangled and damaged their nets. Despite initial monitoring showing the presence of benthic organisms like sponges and soft corals after 6 months of installation and gradually attracting fish to aggregate, lack of follow-ups to the present date brings the AR project impact imperative. While most respondents claimed that water quality in the installed site was maintained after 4 years, the targeted objective to increase fish species abundance was not achieved. Furthermore, some respondents reported that installed ARs were buried due to natural calamities. This study suggests that the AR project in the installed site did not meet the expected output due to a lack of monitoring and poor site selection.

Effectiveness and Impact of Artificial Reef Project in Tigbauan, Iloilo, Philippines: A case study

Abstract

Yapay resifler (AR'ler), özellikle aşırı avlanma alanlarında balıkçılık üretimini artırmak için popüler ve önemli yönetim yaklaşımlarından biridir. Bu bildiride, Tigbauan, Iloilo, Filipinler'deki AR projesinin etkinliğini ve etkisini belirlemek için nitel bir alan araştırması araştırması yaklaşımıyla bir vaka çalışması yapılmıştır. Bulgular, diğer balıkçılar AR'nin parakete avını iyileştirdiğini bildirirken, bölgede kullanılan önemli bir av aracı olan solungaç ağının herhangi bir av değişikliği yaşamadığını; daha doğrusu, bazen ağlarını dolaştırdı ve zarar verdi. 6 aylık kurulumdan sonra süngerler ve yumuşak mercanlar gibi bentik organizmaların varlığını gösteren ve yavaş yavaş balıkları toplamaya çeken ilk izlemelere rağmen, bugüne kadar takiplerin olmaması AR projesinin etkisini zorunlu kılmaktadır. Ankete katılanların çoğu, kurulum yerindeki su kalitesinin 4 yıl sonra korunduğunu iddia ederken, balık türlerinin bolluğunu artırma hedeflenen hedefe ulaşılamadı. Ayrıca, bazı katılımcılar doğal afetler nedeniyle kurulu AR'lerin gömüldüğünü bildirdi. Bu çalışma, kurulu sahadaki AR projesinin, izleme eksikliği ve kötü saha seçimi nedeniyle beklenen çıktıyı karşılamadığını göstermektedir.
