    Territories of the Lobstermen: Good Ocean Boundaries Make Good Neighbors... and Vice Versa
    (1972) Acheson, James M.
    "The rules for lobster fishing territories are especially critical because they control access to the lobsters and because they have important ecological implications at a time when some parts of the marine resource are being over exploited. "Growing up in an inland area of Maine, I was for a long time vaguely aware that territoriality existed among lobstermen. Only recently, however, did I find evidence of these territorial rules and investigate them systematically."

    Value Added, Margins, and Consumer Expenditures for Edible Fishery Products in the United States 1976-78
    (1979) Penn, Erwin S.; Crews, Wenona J.
    "The presentation in value terms of the basic estimates in this study makes it possible to produce analogous figures that can be compared with gross national product value of other industries, and total and per capita expenditures for other food products."

    Oyster Seed Hatcheries on the U.S. West Coast: An Overview
    (1979) Clark, Jerry E.; Langmo, Donald
    "Oyster production in the United States has been diminishing for nearly 80 years. Natural disasters (including disease and predation), pollution, siltation, and land reclamation projects have all contributed to the decline. Present U.S. production is not even equal to what once came from the Chesapeake Bay alone."

    An Investigation of Cree Indian Domestic Fisheries in Northern Quebec
    (1979) Berkes, Fikret
    "Domestic or subsistence fisheries of the eastern James Bay Cree. were studied, mainly in Fort George, by direct observation. These fisheries were characterized by large numbers of participants, low catches per day and per fisherman, but high catches per length of net used, as compared to commercial fisheries. Most stocks appear lightly utilized, but in the vicinity of larger settlements there is evidence that some stocks are overfished. The total catch may be increased by distributing the fishing effort more evenly over a larger area. Fish resource base of the region appears suitable for supporting local economic development with respect to recreational fisheries and native-run commercial fisheries for the local market, as well as maintaining the domestic fishery."

    Southern California Recreational and Commercial Marine Fisheries
    (1976) MacCall, Alec D.; Stauffer, Gary D.; Troadec, Jean-Paul
    "This work should provide significant information for the formulation of positions and plans for regulatory agencies managing these resources. We have attempted to avoid making recommendations regarding the course of future exploitation of southern California fish resources except for the determination of approximate limits of sustainable yields and lower limits on age at first capture. However, where resources are or appear to be exploited beyond maximum sustainable yield, reduction of catch and/or effort is strongly recommended."

    Factor Rents, Sole Ownership, and the Optimum Level of Fisheries Exploitation
    (1972) Copes, Parzival
    "In the literature of fisheries economics there is a noticeable preoccupation with the phenomenon of resource rent dissipation. The common property nature of most fishery resources-with the attendant free entry of labour and capital-gives rise to 'problems' of 'overfishing'. If at any given level of fishing effort the resource should yield a rent to the marginal operator, additional factor inputs of labour and capital will be attracted that will depress the catch per unit of effort and lower returns to all operators. This process will continue until the revenue per unit of fishing effort is reduced to the level of its marginal opportunity cost. Thus the rent attributable to the resource, that formerly accounted for the excess of revenue over marginal opportunity cost, is eliminated."

    Composition of Catches Made by Anglers Fishing for Summer Flounder, Paralychthys Dentatus From New Jersey Party Boats in 1978
    (1979) Christensen, Darryl J.; Clifford, Walter J.
    "Anglers were interviewed while fishing for summer flounder, Paralichthys dentatus, along the New Jersey coast from party boats. Mean seasonal catch rates for full-day and half-day anglers were 3.15 and l .86 summer flounder per man per trip, respectively, from 19 June to 1 September 1978. Other fish species made up less than 10 percent of the catch. A total of 828 summer flounder were measured and ages were determined for 427 specimens. Analysis of the age-length data indicates that /I +, 1Jf +, lV +, V +, and >V + age summer flounder made up 4.3, 73.0, 20.3, l.8, and 0.6 percent of the catch, respectively."
