Marine zooplankton metabolic data - Ikeda, Tsutomu
Since my publication on the statistics of marine zooplankton metabolism (Ikeda 1985; Ikeda et al.

Validity and visualization of a numerical model used to determine dynamic configurations of fishing nets - Suzuki, Katsuya; Takagi, Tsutomu; Shimizu, Takashi; Hiraishi, Tomonori; Yamamoto, Katsutaro; Nashimoto, Katsuaki; ??, ??; ??, ?; ??, ??; ??, ??; ??, ???; ??, ??
To verify the validity of
calculation results using a computational model, we performed the flume tank experiments with a
rectangular net and compared results with those of the numerical simulation of experiments.

Video analysis of fish schooling behavior in finite space using a mathematical model - Suzuki, Katsuya; Takagi, Tsutomu; Hiraishi, Tomonori; ??, ??; ??, ?; ??, ??
The schooling behavior of the fish Parapristipoma trilineatum (chicken grunt) was examined for a range of school sizes
in a water tank containing a central columnar structure using a mathematical model of fish schooling behavior that was
modified from that of Sannomiya and Matuda.

Increase of inbreeding by stocking on wild population assessed by using individual-based life history model - Oota, Takeyuki; Matsuishi, Takashi; ??, ??; ??, ?
When brood stock size
in hatchery is 5 male and 5 female, is the coefficient of inbreeding is about 27 times comparing
th
more when 50 male and 50 female at the 50 generation, and the coefficient of inbreeding
th
increases about five times at the 50 generation, when the sex ratio of the parents changes from 50
males and 50 females to 10 males and 90 females.

It may be pointed out that the stability of fishing boats tend to be poor as the bases of the severe operations and the poor management of loading condition as well as the problem with the restrictions of principal dimensions of ship.

In order to improve the stability and to increase the working area for fishing vessel, bulges are often added on ship sides from underwater part up to upper deck.

For the improvement of the stability and the deck utility, the fitting of a bulge on sidewall of the vessel is one of the solutions.
