 plan to increase their fleet by nearly 40 per- 

 cent during 1966 by purchasing 9 new United 

 States vessels and another 9 new vessels 

 from Mexican builders. (U. S. Embassy, Bo-

MODIFIED METHOD OF RECOVERING 

 OIL AND SOLIDS FROM FILLETING 



PLANT RINSE WATER : 



Danish processors are showing a growing 

 interest in the recovery of oil and protein 

 solids from rinse water used in herring fil- 

 leting. In 1964, a centrifuging recovery proc- 

 ess was installed in Hirtshals, a large her- 

 ring fishing and processing port in Jutland. 

 Similar machinery was ordered by other Dan- 

 ish firms. 



In the spring of 1966, a modified recovery 

 process was installed in a new filleting plant 

 in Skagen. This process involves recovering 

 the oil and protein from the filleting machine 

 wash water by screening off the larger par- 

 ticles, adding chemicals to initiate precipi- 

 tation, concentrating the precipitated solids 

 containing oil and protein, recovering most 

 of the solids in a decanter type centrifuge, 

 and recovering the remaining solids and the 

 oil in a disc centrifuge. Experimental oper- 

 ation has shown substantial profits with high 

 rates of recovery of oil and protein and, as a 

 byproduct, purified discharge water which 

 does not pollute the harbor. A recovery plant 

 of this type capable of handling 20 filleting ma- 

 chines is estimated to costunder US$100,000 

 f.o.b. Denmark. Future experiments are 

 planned with similar equipment for precipi- 

 tating stickwater from ship-and-shore fish- 

 reduction plants. (Regional Fisheries Attache

 pril 27, 196 6.)

FISHERY TRENDS, JANUARY -MARCH 1966: 

 Summary : Danish processors maintained 

 good production of fresh and frozen fillets in 

 the first quarter of 1966 in spite of short sup- 



plies of some species. But there was a drop 

 in output of most other fishery products (par- 

 ticularly fish meal and canned and semipre- 

 served herring) due to a general decline in 

 landings. Average ex-vessel prices were at 

 a high level in the first 3 months of 1966. 



Catch: Landings of fish in local ports by 

 Danish fishing craft during January -March 

 19 66 were 15 percent less than during the 

 same period of 1965 (table 1). Herring land- 

 ings were down 44 percent. Flatfish landings 

 decreased one-third, primarily the result of 

 continued poor catches of plaice.

Partly offsetting the decline were in- 

 creased landings of cod-like fish (mostly 

 small haddock and whiting) which were used 

 mainly for industrial rather than food prod- 

 ucts. Production of pond trout--which is 

 calculated from export data--was 15 percent 

 higher; this may cut into the supply of mar- 

 ketable trout available for sale during the re- 

 mainder of 1966. 



The substantial landings of fish in Danish 

 ports by foreign vessels declined 5 percent. 

 The comparatively smaller landings in for- 

 eign ports by Danish vessels rose 39 percent. 



Prices: Average ex -vessel prices were 

 generally higher during the first quarter of 

 1966 than in the same quarter of 1965 (table 

 2). Prices for plaice, one of the most im- 

 portant export items, were even more than
