Tmmmxmt to Fishing Observers. 
In your capacity as fishing observer it will be necessary 
to keep co plate and accurate data and notes on each day’s operations 
as they will bo the basis for the re orfc of your vessel’s operations. 
You will be responsible for the proper recording on the Grab Boat 
Report and Tlr?.e Study forms. 
These forms are largely self-explanatory. Referring to the 
Crab Boat Report* "area fished '’shall be described as a definite 
part of some bay or with reference to son© point on shore or by 
latitude and longitude if off shore. Under destruction of fish, 
a fairly accurate estimate of undersize marketable fish whicr will 
not live on return to the enter and nosmarketabl® fish shall be 
recorded. The space provided for remarks shall contain a summary 
of the remar'-cs made on each drag on the reverse side of the fora. 
" ffests of various typer, of bottom on the gear shall be noted as 
time progresses. Any unusual circumstances as to catches and fish- 
ing operations, also gear reeoaasandations as to improved methods 
and material®. The reverse aide of the Grab Boat ■ ©port is also 
self-explanatory* Each operation shall be numbered in sequence 
as it is performed. The "Champion" shall use a prefix (A), the 
"Looks" (B), and the "Dorothy" (C) t "Tin© out” and "time in” shall 
be the tine that the net is actually on the bottom fishing and 
not include the time of hauling and setting. hen tangle sets 
are used, the time necessary to haul, clear, repair and set the 
nets shall be incorporated with re arks, A sounding must be taken 
at the beginning and end of each operation, the type of bottom and 
depth in fathoms being noted. 
'hie approximate weight or amber and sixes of various fishes, 
also the various types and relative abundance of other bottom life 
shall be recorded in the column headed "remarks”. her© possible, 
cross bearings on some points on land shall be recorded if operations 
are offshore so as to definitely establish the position of the 
operation. Two lines on the fora will probably be required for each 
drag to provide adequate space. V tracing must be made, from the 
chart covering the area fished , showing the location of each 
operation, depth of water, type of bottom and the direction of 
dragging for each day’s fishing. In addition, the tracing must
