8. Methods of hnndlang nnd preserving the freshness of the catch 



The fish ^-fhioh v/ore captvrcd v/ero irx^.edi^tel.y wrapped in vjcxed pnpor 

 and then further in nevrspopc-o or cloth. They pore 3'.:c'i;cd in two livers 

 in the ship's cold ptoragc space, pr.d '-.he sprees betn-ecn then were filled 

 with crushed ice. The fish r/as not conplptejy Tiozen b.it the refrircrator 

 wns run enough to keep the i«e fror. r/^lting nni to keep t,!-e ter.perrture 

 in the cold stornge spnce cVN^ys ct 3-5° below zero. Results were better 

 where the fish were Tjrnppcd in cloth than ?»hen they were v;rrppcd in news- 

 p^.per. There were sone fish, hovjever, which tiu:'ned gray -nd lost their 

 value.

11. Opinions regarding the vessel, gear, fishing r.ethcds, fishing 

 grounds, and fishing season 



(a) It would be desirable to have a large vessel of the 200-300 ton cl."ss, 

 designed purely for longlino fishing, vvith large fishholds like those of 



a transport vessel, equipped with refrigeration and, of coiorsc, insulation, 

 and able to rerajin at sea for at least one nonth or noro. 



(b) For the trunk lines 8- nonme cotton line like that used by this vessel 

 appeared sr'tisfactory. Good results were had by using sir.ilnr 7 or S-ronme 

 cotton for the branch lines with fine v/iro for the leaders. Swivels were 

 put in all of the branch lines. 



(c) As for fishing method, setting of the lines v/r's conpletod early in 

 the morning and cfter cne patrol along the lines hauling in \7as borun. 

 In longline fishing the schools are not seen '^nd the lines ."re set "dth 

 reference to the water temperature and color and the F.bundance or sc.ircity 

 of plankton, therefore it is necessary tn use a great amount of gear. The 

 line hauler h?s to be run a great deal r-nd should be constructed so that 

 when there are no fish on the lino it can be hauled at high speed rnd so 

 that the lines will not be abraded. 



(d) The fishing grounds change with the senson, but during the same season 

 the fishing is good in Areas I f^nd II in the highest latitudes which the 

 v/arm current reaches and where the vrater tom.perature is 15-16.5'-'. The 

 Dlbricore is, "fter all, a fish which swims at the stirfice ^nd thoreff^ro 



It is thought that in the siamx:or season the branch linos r.ight be shortened, 



(e) Fishing seasons are from Ivioy to July .'md from 3optcm.bcr to Deconbcr. 

 It appears that in August there is a seasonal scarcity of fish.
