Crop production systems have adopted cost-effective, sustainable and environmentally friendly agricultural practices to improve crop yields and the quality of food derived from plants. Approaches such as genetic selection and the creation of varieties displaying favorable traits such as disease and drought resistance have been used in the past and continue to be used. However, the use of biostimulants to promote plant growth has increasingly gained attention, and the market size for biostimulants is estimated to reach USD 4.14 billion by 2025. Plant biostimulants are products obtained from different inorganic or organic substances and microorganisms that can improve plant growth and productivity and abate the negative effects of abiotic stresses. They include materials such as protein hydrolysates, amino acids, humic substances, seaweed extracts and food or industrial waste-derived compounds. Fish processing waste products have potential applications as plant biostimulants. This review gives an overview of plant biostimulants with a focus on fish protein hydrolysates and legislation governing the use of plant biostimulants in agriculture.
农作物生产系统已经采用了具有成本效益、可持续和环保的农业实践，以提高作物产量和植物源性食品的质量。过去和现在都在使用诸如遗传选择和创造表现出有利特性（如抗病和抗旱）的品种等方法。然而，使用生物刺激素来促进植物生长越来越受到关注，预计到 2025 年，生物刺激素市场规模将达到 41.4 亿美元。植物生物刺激剂是从不同的无机或有机物质和微生物中获得的产品，可改善植物生长和生产力，并减轻非生物胁迫的负面影响。它们包括蛋白质水解物、氨基酸、腐殖质、海藻提取物以及源自食品或工业废物的化合物等材料。鱼类加工废物有作为植物生物刺激素的应用潜力。本文综述了植物生物刺激剂，重点介绍了鱼蛋白水解物以及农业中使用植物生物刺激剂的法规。
