| 内容記述 | In the investigation for the further improvement of fishery productivity in Inland Sea and its adjacent waters, energetic study on the community of consumer level, especially on the fish resources, are thought about one of the important biological problems. Therefore, in our program, stomach contents analysis of the important fishes were carried out in large scale. In this stomach content analysis, after the identification of the prey, its length and weight must be known respectively : the case that the stomach content are some fish, skeletal parts of the fish can be measured even when the fish are digested more or less, and we usually see that the columns from the central part of vertebral bone are rather complete. So, if we have the relation between Vertebral Column Length (V. L) and Body Length (B. L) or Body Weight (B. W), we can restore the length and weight of prey found in the stomachs. We checked the Vertebral Column Length (V. L. ) Curves (Fig. 1, 4, 6) and the coefficent of variance (C. V.) of the ratio (V.L. /B.L.) (Fig. 2, 5, 7). ; and we decided to use the column length of the central part of vertebral bone for the restoration of prey size, considering the stability of estimates. Length of 6 to 3 columns of the central part of vertebral bone are measured practically (Fig. 8), and the mean length of them are caluculated as the vertebral column length (V.L) data. At the same time, measurements on body length (B. L) and body weight (B. W) were carried out. Then we got the relation betweem them. Each graph for estimation (pp. 210-228) consists of the following three parts : 1) Relation between Vertetral Column Length (V. L. ) and Body Length (B. L. ) (or Anal Length (A. L.)). 2) Relation between B. L. (or A. L. ) and Total Length (T.L.) (or Fork Length (F.L.)). 3) Relation between log T. L. (or log. A. L. ) and log B. W. Then if we identify the species of the stomach content, we can estimate graphically the B.L., T. L. and B. W. of them from the measure of V. L. Fitted straight lines defined as follows are drawn in these graphs and six parameters, a, b ; m, n ; and p q are shown in Table 1. (B. L) = a (V.L) +b …. (1) (T.L) = m (B.L) +n …. (2) log(B. W) = p . log (T. L) +q .... (3) Graphs have been drawn on 76 species up to now, and we hope to get further those imformations, concerning other fishes, or larval and juvenille stage of those fishes, as one of the fundamental need for the fishery, biolgy. and also for the community study. In practice of stomach contents analysis, the measurements of V. L. and B. L, if possible, will be much helpful to reduce the scope of searching for identification. Fig. 9 shows the range, dispersion (ơ ) and mean of V. L/B. L-values by species. Differences between those V. L/B. L-value give the auxiliary key, and are useful imformations in addtion to those given in the former report. (TAKAHASHI 1962). | |||||
