针对大规模水面养殖资产难以直接全面盘点的特点，公司阐述了其盘点方法。公司定期（通常在报告期 末或下年初）组织内部水产管理人员、财务人员并会同外部水产专家，前往各捕捞现场进行核查。盘点 主要依赖于核定关键参数（如存活率、综合生长系数）并结合数学模型来估算期末结存数量。为验证此 方法的准确性，公司还引入了中国科学院水生生物研究所的专家团队，利用水声学频差技术对鱼类资源 进行探测。该技术通过宽频回声探测仪收集声学数据，分析鱼类大小、分布密度，从而对账面数量进行 佐证。公司指出，近三年的探测结果与账面数量的误差率均在正负10%至20%的合理区间内，总体误差 率控制在10%以内，认为其参数设定和计算方法具有合理性。 在减值测试方面，公司解释了近一年又一期未对消耗性生物资产计提跌价准备的原因。公司定期计算各 类生物资产的可变现净值，其依据是预计售价（参考近期或临近月份平均销售价格）减去预计至完工时 尚需发生的捕捞费和相关税费。公司将测算出的可变现净值与存货的账面成本进行比较。根据披露的测 算过程，无论是2024年末还是2025年6月末，公司各渔场消耗性生物资产的可变现净值均高于其账面成 本，因此未发现减值迹象，无需计提存 ...
