Hawaii H-6-R Henry M. Sakuda $5,464 



Management and development investigation of the Kona crab (Ranina serrata) - The aims 

 of this project are to develop and manage the Kona crab fishery. The biology is 

 studied as is the extent and abundance of crabs on the fishing gro-unds. Exploratory fish- 

 ing and gear development for more effective methods of harvesting the resource are 

 studied . 



Oregon 1-5-R Paul H. Reed $15,210 



Controlled rearing of dungeness crab larvae and the influence of environmental conditions 

 on their survival - This project at Oregon State University's Marine Science Center 

 at Newport aims to develop techniques for the identification and rearing of dungeness crab 

 larvae and to study how dissolved oxygen concentrations, temperature, and salinity affect 

 the larvae distribution and survival of larvae. The feasibility of hatching and rearing 

 crab larvae on a commercial basis is explored. 



Rhode Island 3-43-R Andreas Holmsen $29,500 



Investigation of the deep sea red crab (Geryon quinquedens) - The aims of this project are to 

 determine the cost involved in handling the crab, both on a trawler and in a processing 

 plant, and to determine the market characteristics of the crab. 



Rhode Island 3-46-R George W. Gray, Jr. $7,700 



Investigation of the basic life history of the red crab - The aim of this study is to 

 determine growth, age at sexual maturity, spawning and moulting seasons, migratory behavior, 

 and natural mortality of the red crab. Present work is concerned with finding a 

 satisfactory way of marking the crab, finding a reliable sampling technique, and deter- 

 mining the growth of adult (larger) male crab by using length frequency data. 



Lobster : 



Connecticut 3-44-R William Lund, Jr. $23,500 



Investigations on the lobster - The population structure and ecology of a designated area 

 near Ram Island are being studied with the use of SCUBA gear. Routine observations are made 

 to determine movement, behavior, and bottom type preferred by lobsters. Plankton tows are 

 also made weekly during the spring and summer to define the period when lobster larvae 

 are present. 



Hawaii H-5-R Henry Sakuda $4,lti7 



Management investigation of two species of spiny lobsters. Panulirus .japonicue and P. 

 penicillatus - This study is designed to evaluate the catch statistics of the net and trap 

 fishery and to analyze previously collected data relative to migration, molting frequency, 

 growth, and reproduction. 



Maine 3-U-R James Thomas $60,000 



Lobster research program - This study is concerned with obtaining and analyzing biological 

 and statistical data on the inshore lobster fishery for management purposes. Catch statistics 

 from 152 dealers located throughout the coastal counties are being analyzed. Samples are 

 also taken each month from 10 different locations along the inshore area to determine changes 

 in length, weight, sex ratio, and maturity of the lobster. 



Mussel: 



Illinois 4-13-R William C. Starrett Completed 1968 



Clam industry in Illinois - The Department of Conservation has completed a study 

 to formulate a sound basis for managing the mussel industry. The work involved an 

 inventory of the clam fisheries on the Illinois, Mississippi, and Wabash Rivers.
