Definisi:
• Stock - groups of fish of one species that interbreed
and share a common gene pool (Shaklee & Salini
1985; Milton & Shaklee 1987);
• Stock – subset of one species having similar
population parameter and inhabiting a particular

geographic area (Sparre & Venema, 1989) - discrete
groups of animal which show very little mixing with
the adjacent group;
• In terms of fish stock assessment – a group of animal
for which the geographical limits can be defined

1. Places where Sardinella lemuru was found
2. Bali Sardinella = Sardinella lemuru, not
others

• Morfologi: Morfometri,
• Morfologi: meristik dan penciri lain (warna,
bercak)
• Genetik – susunan basa (base-pair) – analisis
DNA
