 1. Survey Objectives |
|
|
Focusing on fishes, this survey collected
information from scuba divers and snorkelers
on the distribution of coastline life-forms.
Their distribution is shown on a map, the
"sea creature map." This map is
a resource for learning more about coastal
water environments and also for undertaking
protection measures.
Together with these purposes, by providing
divers with concrete objectives of sea environment
observation, the survey should promote the
spread of undersea observations. |
|
| 2. Survey Content and Methods |
|
|
| The survey was done with the cooperation of volunteer scuba divers and snorkelers. 43 target species selected by The Environment Agency(*) were researched with reference to a "handbook". The volunteers recorded species codes and survey location codes using a 1:50,000 grid area map. |
|
| 3. Survey Results |
|
|
|
1,565 volunteers in 134 groups covered important
diving spots from Hokkaido to Okinawa.
The survey was done using 512 grids (Standard Area Grid, also called "the 3rd grid", about
1 kilometer square) and 15,520 items of data
were collected.
Until now, marine organisms distribution
surveys focusing on fishes relied on information
from specialists and data on fish catches.
However verification of the data was not
sufficient. This survey has provided the
first map of marine organisms distribution
based on a uniform method of undersea observations
done in a relatively limited period of time.
