    Description: Throughout the northeastern United States, aquaculture operators face a wide variety of laws and regulations that govern the manner in which they plan, site, and operate aquaculture facilities. Many local, state, and federal laws and regulations have been designed to enable aquaculture to exist as a viable industry and to flourish. It is obvious that aquaculture cannot be conducted in the absence of a legal system that establishes property rights, provides a means for the enforcement of these rights, and ensures the safety of the product for consumers. Although a legal framework is necessary for aquaculture to exist as an industry, there are many instances where uninformed, outdated, or inappropriate regulatory regimes impede aquaculture development (DoC 1999; MCZM 1995; Ewart et al. 1995; Rychlak and Peel 1993; Bye 1990; DeVoe and Mount 1989; Kennedy and Breisch 1983; NRC 1978). Inconsistencies in the law can lead to an uncertain legal environment for aquaculturists.1 Regulators are put in the conflicting position of promoting the development of the industry and regulating its effect on other uses of the land and sea (DeVoe 1999; NRC 1992). Operators are sometimes forced to undertake activities while lacking adequate information or a complete understanding of laws and regulations. Conflicts and concerns often may be left unresolved until an issue is brought before an adjudicatory body. Legal constraints such as these detract from the stability and certainty that otherwise would facilitate sustainable aquaculture development, slowing or halting the growth of the industry, or perhaps even leading to its decline. Such constraints make the statements quoted above as true today as they were 35 years ago. Policies that both facilitate and constrain aquaculture have been reviewed by a number of commentators (McCoy 2000; Brennan 1999; Barr 1997; Reiser and Bunsick 1999; Reiser 1997; Hopkins et al. 1997; Rychlak and Peel 1993; Eichenberg and Vestal 1992; Wildsmith 1982; Kane 1970). In 1981, the US Fish and Wildlife Service sponsored a comprehensive review of aquaculture regulation across the nation (the “Aspen Report”). The report’s authors identified at least 120 federal laws that, at that time, either directly (50 laws) or indirectly (70 laws) affected aquaculture. Further, the authors found more than 1,200 statutes regulating aquaculture in 32 states (ASC 1981). An important finding of the Aspen Report was that aquaculture businesses must obtain at least 30 permits, on average, in order to site and operate their businesses. McCoy (2000) concludes from his review of the Aspen Report and other studies that aquaculture may be the most highly regulated industry in America.2 In its responses to periodic surveys of constraining factors, the industry seems to agree with McCoy by consistently ranking legal and regulatory constraints near the top of the list of factors. Wypyszinszki et al. (1992) begin to assemble the body of law relating to marine aquaculture in the US Northeast, although their work remains unfinished due to insufficient resources. A number of excellent analyses emerged from that effort, including a study of the public trust doctrine by Eichenberg and Vestal (1992) and a study of “reverse regulation” of the oyster industry in Long Island Sound.3 Here we examine a range of aquaculture policies in an effort to identify those laws and regulations that may impede development unnecessarily within the northeastern United States. Through a survey of industry and government officials and a review of the literature, we find that specific laws and policies or the absence of laws and policies can be argued to impose constraints on growth in certain segments of the industry.

    Notes: 〈list xml:id="l1" style="custom"〉1 The terrestrial-aquatic interface beneath a riparian corridor was investigated as a region of hydrological and biological control of nutrient flux. Subsurface flow paths were defined from the channel toward the riparian zone and also from the riparian zone toward the channel using tracer-injection studies. Solute transport had a rapid channel component (m min−1) and a slow hyporheic flow component (mh−1, m day−1). Subsurface flow beneath the riparian zone approximated a straight path entering at meanders but could also cross beneath the stream, possibly using relic channels.2 Dissolved oxygen (DO) concentration in the hyporheic zone ranged from 〈1.0 to 9.5mgl−1 due to permeability variations in bankside sediments. DO concentration was related to the proportion of stream water in the lateral hyporheic zone, indicating that the channel water was the DO source.3 The magnitude and riming of lateral water exchange was linked to previously published studies of nitrification and denitrificarion. Both nitrification potential and channel exchange decreased with distance from the channel and were absent at sites lacking effective exchange, due to low DO. Field amendment of ammonium to an aerobic flow path indicated nitrification potential under natural hydrological conditions. Denitrification potential was inversely related to channel exchange and was insignificant in channel sediments. Field amendment of acetylene plus nitrate to a flow path with low DO and minimal channel exchange indicated denitrificarion of amended nitrate.4 Comparison of hydraulic head to distribution of the biologically important solutes DO, ammonium, and nitrate was useful for interpreting previous findings and conceptualizing the riparian zone as a functioning ecotone between terrestrial and aquatic systems.

    Notes: Abstract Sediment (0.5 mm–2.0 mm grain size) was incubated in nylon bags (200 μm mesh) below the water table in the channel and in two transects of shallow wells perpendicular to the banks (to 18 m) of a third-order stream during August, 1987. One transect of wells drained steep old-growth forest, and the other a steep 23 year-old clear-cut partially regenerated in alder. At approximately 6-week intervals between October, 1987, and June, 1988, bags were retrieved. Total exchangeable ammonium was determined on sediment, and dissolved oxygen, nitrate and ammonium were determined in stream and well water. Exchangeable ammonium ranged from 10 μeq/100 g of sediment in the stream where nitrification potential and subsurface exchange with stream water were high, to 115 μeq/100 g sediment 18 m inland where channel water-groundwater mixing and nitrification potential were both low. Sorbed ammonium was highest during summer/autumn base flow and lowest during winter storm flow. Both channel and well water contained measurable dissolved oxygen at all times. Ammonium concentration was typically 〈 10 μg-N/L in channel water, increased with distance inland, but did not exceed 365 μg-N/L at any site. Nitrate concentration was typically higher in well water than channel water. Nitrate levels increased dramatically in wells at the base of the clear-cut following the onset of autumn rains. The results indicate a potential for temporary storage of ammonium on riparian sediments which may influence biotic nitrogen cycling, and alter the timing and form of dissolved inorganic nitrogen transport from the watershed.

    Notes: Abstract Nitrate reduction and denitrification were measured in swamp forest streams draining lowland rain forest on Costa Rica's Atlantic slope foothills using the C2H2-block assay and sediment-water nutrient fluxes. Denitrification assays using the C2H2-block technique indicated that the full suite of denitrifying enzymes were present in the sediment but that only a small fraction of the functional activity could be expressed without adding NO3 −. Under optimal conditions, denitrification enzyme activity averaged 15 nmoles cm−3 sediment h−1. Areal NO3 − reduction rates measured from NO3 − loss in the overlying water of sediment-water flux chambers ranged from 65 to 470 umoles m−2 h−1. Oxygen loss rates accompanying NO3 − depletion averaged 750 umoles m−2 h−1. Corrected for denitrification of NO3 − oxidized from NH4 + in the sediment, gross NO3 − reduction rates increase by 130 umoles m−2 h−1, indicating nitrification may be the predominant source of NO3 − for NO3 − reduction in swamp forest stream sediments. Under field conditions approximately 80% of the increase in inorganic N mass along a 1250-m reach of the Salto River was in the form of NO3 − with the balance NH4 + . Scrutiny of potential inorganic N sources suggested that mineralized N released from the streambed was a major source of the inorganic N increase. Despite significant NO3 − reduction potential, swamp forest stream sediments appear to be a source of inorganic N to downstream communities.

    Notes: Abstract The subsurface riparian zone was examined as an ecotone with two interfaces. Inland is a terrestrial boundary, where transport of water and dissolved solutes is toward the channel and controlled by watershed hydrology. Streamside is an aquatic boundary, where exchange of surface water and dissolved solutes is bi-directional and flux is strongly influenced by channel hydraulics. Streamside, bi-directional exchange of water was qualitatively defined using biologically conservative tracers in a third order stream. In several experiments, penetration of surface water extended 18 m inland. Travel time of water from the channel to bankside sediments was highly variable. Subsurface chemical gradients were indirectly related to the travel time. Sites with long travel times tended to be low in nitrate and DO (dissolved oxygen) but high in ammonium and DOC (dissolved organic carbon). Sites with short travel times tended to be high in nitrate and DO but low in ammonium and DOC. Ammonium concentration of interstitial water also was influenced by sorption-desorption processes that involved clay minerals in hyporheic sediments. Denitrification potential in subsurface sediments increased with distance from the channel, and was limited by nitrate at inland sites and by DO in the channel sediments. Conversely, nitrification potential decreased with distance from the channel, and was limited by DO at inland sites and by ammonium at channel locations. Advection of water and dissolved oxygen away from the channel resulted in an oxidized subsurface habitat equivalent to that previously defined as the hyporheic zone. The hyporheic zone is viewed as stream habitat because of its high proportion of surface water and the occurrence of channel organisms. Beyond the channel's hydrologic exchange zone, interstitial water is often chemically reduced. Interstitial water that has not previously entered the channel, groundwater, is viewed as a terrestrial component of the riparian ecotone. Thus, surface water habitats may extend under riparian vegetation, and terrestrial groundwater habitats may be found beneath the stream channel.
