Seasonal dynamics of egg laying and egg-laying strategy of the ectoparasiteArgulus coregoni(Crustacea: Branchiura)

open access: yesParasitology, 2004
Substrate preferences, spatial aggregation patterns and seasonal dynamics in the egg laying of ectoparasiticArgulus coregoniwere studied at a commercial fish farm in Finland. Pilot experiments showed thatA. coregonifemales selected specific types of substrates for egg laying. Significantly moreA.

Some Ecological Notes on the Egg Deposition of Argulus coregoni THORELL (Crustacea, Branchiura)

open access: yesFish Pathology, 1980
Laboratory and field experiments were made to examine the effects of time of day, water depth, and roughness of substrata on the egg deposition of Argulus coregoni. Egg-laying occurred normally at night (98%, 93/95) ; however, mature females laid eggs even in the daytime under experimentally dark conditions.
