First In Still Here (FISH)is an informal industry term humorously describing inventory that has not moved for a long time—often applicable to obsolete or slow-moving items, such as outdated electronics. The CLT “Inventory Control” discussion of stock rotation and turnover stresses avoiding “FISH” inventory, which ties up capital and warehouse space. Electronic products rapidly lose value or technological relevance, so identifying and clearing stagnant stock is vital. CLT encourages usingABC analysisand continuous review to highlight FISH items for markdown, return, or disposal. While not a formal control method like FIFO or JIT, understanding FISH alerts managers to inefficiencies that hinder inventory flow and profitability.
