Numerous attempts have been made to estimate the production in the sea of fish and other organisms of existing or potential food value to man (1-4). These exercises, for the most part, are based on estimates of primary (photosynthetic) organic production rates in the ocean (5) and various assumed trophic-dynamic relationships between the photosynthetic producers and the organisms of interest to man. Included in the latter are the number of steps or links in the food chains and the efficiency of… Expand

Marine organisms and their contribution to organic matter in the ocean
Abstract The best estimates of marine biomass can be made for the algal component. Estimates of the biomass of small animals and bacteria both in the water column and the sediment remain beset withExpand
Food Resources of the Oceans: An Outline of Status and Potentials
TLDR
Man must quickly establish and implement a rational, global management plan for the world's oceans and control his own population numbers to ensure conservation of the marine food-resources. Expand
Photosynthetic production and its regulating factors in the Baltic Sea
TLDR
Of the micronutrients controlling productivity in the photic layer of the Baltic Sea, nitrate has a stronger limiting effect on plant growth than phosphate, a fact which is in agreement with existing conceptions on the subject. Expand
Remote sensing of marine photosynthesis
The oceans occupy 70% of the earth’s surface, and estimates of their contribution to global photosynthesis range from 10% to 50% (Perry, 1986) or 20 to 50 × 1015 g C y−1 (McCarthy, 1984; Martin etExpand
From Individual Plankton Cells To Pelagic Marine Ecosystems And To Global Biogeochemical Cycles
It is often assumed that the biological CO2 pump in the oceans is essentially driven by the upward flux of NO3, so that the potential export of biogenic carbon from the upper ocean isExpand
The Resources of the Ocean
Resources can be of two basic types: those, such as food, that are renewable because they can be replaced by the growth of plants and animals, and those, such as most mineral resources, includingExpand
The Biological Pump
The biological pump is the set of processes by which inorganic carbon (e.g., carbon dioxide) is fixed into organic matter via photosynthesis and then sequestered away from the atmosphere generally byExpand

TLDR
The total amount of the primary production that is appropriated by humans from both marine and terrestrial food webs is useful in understanding the limits to total food production on the planet as well as the consequences of this demand for other species. Expand
An ecosystem ecology perspective on artificial reef production
Predicting the overall productivity of an ecosystem is a long-standing challenge in ecology and conservation biology. Understanding controls of primary production is important in both theoretical andExpand
PRODUCTIVITY OF DIATOMS IN CULTURE AND IN MARINE HABITATS
The diatom dominated phytoplankton net primary production in different areas of the ocean (from 100-1000 mg C. m. day) and in estuaries (up to 2000 mg C. m. day) is compared with the maximumExpand

The Potential Harvest of the Sea
Abstract Postwar growth of world marine fisheries has been rapid, from 17 million metric tons in 1948 to 40 million in 1962, and recently seems to have accelerated. Crude estimates of the potentialExpand
Extracellular products of phytoplankton photosynthesis
TLDR
It thus seems likely that the widely used method, in which fixation of 14C in particulate matter only is determined, underestimates total primary productivity, and labelled organic substances in the water are probably liberated by intact photosynthesizing cells rather than by breakage of cells during filtration.

The Protein Metabolism of Sunfishes of Different Ages
TLDR
The subject has biological interest because of the phylogenetic position which fishes occupy among the vertebrates and aquatic ecologists who are concerned with the problem of production as defined by Clarke (1946), and from this standpoint that the writer has initiated the present experiments.
