Sokołowska E., Skóra K.E., 2001. Fecundity of ninespine stickleback (Pungitius pungitius L., 1758) in the Puck Bay. Acta Ichthyol. Piscat. 31 (1): 45-60. The material was collected in the spring-summer period of 1993 and 1995-96.

Ninespine stickleback is abundant in the brackish waters of the Puck Bay and its catchment area. The species is common in the overgrown littoral zone. Spawning in the bay is extended, lasting from March to August, the eggs are laid in batches. The fecundity of these fish is relatively low, as with others which show parental care. Sticklebacks lay up to 199 eggs, this being higher than the fecundity of sticklebacks from North America and Eastern Europe and lower than in one of the Japanese forms. The relation between absolute fecundity and body length, and body weight is described by the equations: F = 1.8052ּ10-3ּL2.71 and F = 103.77551ּW0.99, respectively. The fecundity of a fish depends primarily on its weight. The body size and fecundity had no effect on egg size.
