Details for individual operations as vfell as for different 

 home ports ore shown in table IV - I4J4. 



Vesoels ranging froia 1,0 to 60 feet in length on the average 

 consvaaed between 12,000 and l6,000 gallons of fuel annually. Average 

 consumption per hour at sea, according to the figures per 12-hour fish- 

 ing day shown in the tahle, was approziiiiately five gallons for these 

 vesoels. Per pound of shriEjp tolccn, fuel coneumption averaged close to 

 one third of a gallon. The vessel in excess of 60 feet in length con- 

 sumed on the average over 27,000 gallons of fuel annually 6uid at least 

 10 gallons per hour at sea. In terms of the number of pounds of shrimp 

 taken, fuel consumption of the larger vessels, except In one instance, 

 did not differ appreciably froa that of the smaller vessels. 



Engines vlth less than 100 horsepower were significantly more 

 econcmlcal than the larger engines. Two of these emaller engines had an 

 average annual consumption of fuel of about 10,000 gallons and an hourly 

 consvjoption of less than four gallons. ConouEiption par poxmd of shrimp 

 taken, in these operations, was slightly more than one- fifth of a gallon. 

 The average consumption of fuel of the bigger installations was appre- 

 ciably higher, with 120-and I70- horsepower engines averaging approximate- 

 ly ten gallons per hour. Three 165-horsepower engines of a different 

 make fraa the other more poijorful engines were considerably more econom- 

 ical, consuming on the average lees than six gallons per hour. 



If it is assumed that the average cost of fuel at the time 

 the cuirvey was made, was between 11 and 13 cents per gallon, total 

 annual fuel costs of the vescelo making up the eeiuple includod in the 

 t\JO tabulations above ranged anyvhere frcai about $1,000 to $l|-,000. 

 Since the number of couple observations was considerably larger in the 

 Federal Trade CoiLmission study than in the Han/ell, Knowles and Asso- 

 ciates survey, the range of total annual fuel costs was consequently- 

 wider. 



The amovmt of Ice required to maintain a certain sttindard of 

 quality depends on numerous factors, oinong which are the material used 

 in the construction of the vescel (wood or steel), the capacity of the 

 hold, the material used for the Inculation of the hold, the time of the 

 year, the size of the catch, and the type of ice used for chilling. 



Among other factors, the length of time which the shrinip Is 

 to be stored in the vessel's hold will dstenmine the ©Mount of ice that 

 must be carried. In Louisiana, the lugger-type vessel which shrimps 

 for eight or ten hours occasionally carries no ice at all. In such 

 case the Bhrlmp are protected by an axming which is spread over the 

 vessel's deck. Trips to Campeche require that the vessel carry 30 or 

 more tons of ice. 



Total annual consumption of Ice on vessels for which data 

 were obtained by Harwell, Knoxrlec and Aasociates ranged from I69.5 

 tons for one vessel with a 7-ton hold capacity operating out of
