“…Tsikliras and Polymeros' (2014) findings showed that larger fishes were consistently attaining higher market value than their small and medium counterparts. In a study conducted by Dar et al (2015), the capture of juvenile fish elicited enormous economic loss in selected landing centers in India. Zimmerman and Heino (2013) accentuated that change in catch composition greatly influences size-dependent pricing.…”

“…Growth overfishing occurs when there is massive removal of immature fish, which impedes the ability of fish stocks to replenish themselves. It is regarded as detrimental because it may further aggravate the current problem of resource depletion (Green et al 2003;Kamei et al 2013;Dar et al 2015). Moreover, the capture of fish below its marketable size induces a potential loss of revenue due to its lower market value.…”

The continuing decline in catch rates instigates various fishing adjustments to keep up with the demands of a growing population. Fishery resources are being caught before they can attain their optimum harvestable size. Undersized catch elicits lower economic value; thus, considered as losses in postharvest fisheries. The present study focused on generating actual data on the volume of undersized catches in selected landing sites in the Philippines. It aims to quantify the magnitude of postharvest and financial losses incurred from catching fishery commodities below their marketable sizes. The estimated loss at 0.97% and 4.02% for capture and aquaculture commodities, respectively, was equivalent to PHP 15,235,290 financial loss. Estimation of losses by commodity showed that squid recorded the highest at 20.14%, followed by tilapia (9.61%), blue swimming crab (4.48%), shrimp (2.75%), small pelagics (1.98%), mussel (1.46%), oceanic tuna (0.91%), by-catch (0.79%), milkfish (0.09%), and oyster (0.02%). Excessive catching of undersized BSC and squid in Western Visayas may lead to overexploitation of resources and may adversely affect subsequent recruitment in the long run. The study's results indicate that catching undersized species could lead to substantial postharvest losses and subsequent loss of potential revenue to the industry players. Allowing the stocks to attain their maximum biomass level will minimize postharvest losses; thus, maximizing utilization of resources and benefits derived from the sector. Unrestrained catching of undersized fishery commodities undermines resource sustainability, economic potential, and food security. The strengthening of regulatory frameworks is, therefore, necessary to address both economic and ecological impacts.
