Abstract

Fisheries provide critical sources of employment, nutrition, and economic value for many countries, making fishery resources an essential component of natural capital. Accordingly, their efficient and sustainable management is fundamental for long-term development. One approach to evaluate sustainability is through the estimation of wealth, defined as the present value of profits derived from fishery assets. While previous global studies have estimated the natural wealth of fisheries -including for Peru- these assessments often omit processing profits, leading to potential underestimations. This study improves upon existing estimates by incorporating both extraction and processing profits to calculate Peru’s fishery wealth over the period 1994–2022. Results reveal a 51 % increase in wealth during this timeframe. Moreover, the analysis shows that processing profits significantly exceed resource rents, highlighting the importance of including them to avoid substantial distortions in fishery wealth valuation.

秘鲁渔业财富

渔业为许多国家提供了重要的就业、营养和经济价值来源，使渔业资源成为自然资本的重要组成部分。因此，有效和可持续的管理是长期发展的根本。评估可持续性的一种方法是通过对财富的估计，其定义为渔业资产所得利润的现值。虽然以前的全球研究估计了渔业的自然财富，包括秘鲁的渔业，但这些评估往往忽略了加工利润，导致潜在的低估。本研究在现有估计的基础上进行了改进，将开采和加工利润纳入计算秘鲁1994-2022年期间的渔业财富。结果显示，在这段时间内，财富增长了51% %。此外，分析表明，加工利润大大超过资源租金，突出了包括加工利润以避免渔业财富估值严重扭曲的重要性。
