The variation in the weight of individuals with same age and the age-specific maturation ratio of white-spotted charr Salvelinus leucomaenis are examined in Furuu River in Hokkaido. The variance in the age-specific weight is extremely high and the strong intraspecific competition is expected to occur in the population. The maturation ratio of females in the stream is zero at any age and that of males in the river ranges from about 21 % to 58 % depending on age. It is shown that (1) it is a rare event for females to mature in the river, (2) the proportion of maturing in the river is about 21 % in males with 2+ age and (3) there is a possibility that both males and females with 5+ age in the river migrate to the sea. (4) about 25 % of sea-run individuals are immature.

Objective: To evaluate the usefulness of diagnostic laparoscopy in patients with advanced ovarian cancer.Methods: We retrospectively analyzed nine patients for whom primary debulking surgery was considered unfeasible. We evaluated whether laparoscopic procedure was adequate in making pathological diagnosis and intraabdominal assessment.Results: Median age was 63 years (range, 47-79 years), and median operation time was 59 minutes (range, 43-103 minutes). All nine patients were pathologically diagnosed with high-grade serous carcinoma and were considered unfit to undergo primary debulking surgery. All patients received chemotherapy. Six patients underwent interval debulking surgery. Only one patient showed mild adhesions between the omentum and the abdominal wall. Conclusion: Diagnostic laparoscopy is safe and feasible in advanced ovarian cancer patients.
