Subramaniam, Thatchaneshkanth Hong, Hyun-Ki Park, Kyung-Il Cho, Young-Ghan Choi, Kwang-Sik Animals Bivalvia Female Republic of Korea Reproduction Gonads Alveolata Host-Parasite Interactions In the intertidal zone, the reproductive dynamics of bivalves are influenced by both biotic and abiotic factors, including spatial and temporal fluctuations in sea surface temperature (SST), food availability, and diseases. Notably, disease proliferation is markedly enhanced under conditions favorable to pathogen entities, such as elevated SST and low food availability. This study examined the associative impacts of Perkinsus olseni parasites on the reproduction of the Manila clam Ruditapes philippinarum, across a latitudinal range covering four sampling sites along the west and south coasts of Korea, ranging approximately 400 km. In late June, we collected adult female clams to assess their condition index, reproductive output, and the prevalence of P. olseni infection. Histology indicated that 94 % of clams from SJ tidal flat, the cooler northwest coast were in the ripe stage. In contrast, clams from WD and GS, the warmer regions of the southwest and south exhibited more progressed stages of gonadal maturation, including the spent and resting phases. Notably, clams at the ripe stage in WD and GS demonstrated significantly lower gonad somatic index (GSI, P |
