Fishery preservation

There is a current control system for certain types of biocidal products (known as non-agricultural pesticides) operated by HSE under the Control of Pesticides Regulations (CoPR). These are antifouling products, insecticides, wood preservatives and surface biocides. Additionally agricultural pesticides are controlled under CoPR but these are administered by the Pesticides Safety Directorate (PSD), an executive agency of the Ministry of Agriculture, Fisheries and Food (MAFF). 

Not every fishing system works as well and preserves fish as long as the ones used in Iceland and Norway. Spoilage at sea is very common and contributes substantially to the loss of fishery resources. Several factors affect the keeping quality of fish held cai trawlers. One factor is the temperature of the water from which the catch is taken. Fish from hi temperature water needs less chilling to inhibit enzyme activity fish from very low temperature waters need very low temperature chilling to retard enzyme activity (13). 

Ostermeyer (87) described the rapid and sensitive determination of acesulfame, saccharin, aspartame, SA, and BA in fishery products. Aspartame is determined directly in the aqueous extract of samples. For the other additives, cleanup of the extract is performed by anion-exchange chromatography. Ostermeyer used a Nucleosil 100-5 C lg (Macherey-Nagel) (250 X 4 mm, 5 /xm ) column and 0.02 mol/L KH2P04 acetonitrile as mobile phase and 219 nm detection using a diode array detector. Recoveries of spiked samples at concentrations of 50-400 mg sweetener/kg and 50-4000 mg preservative/kg were in the range 84-102% for all analyzed substances (87). The HPLC conditions for the determination of OAs are summarized in Table 5.

There are other such examples. Many unsaturated soils are known to convert to N2(g> via NO3 (i.e., nitrification then denitrification). They achieve this because there are local oxic and anoxic environments in the soil waters that, respectively, allow nitrification and denitrification to proceed. In stratified lakes, nitrification may occur in the oxygenated epilimnion (upper layer) and denitrification in the hypolimnion (bottom water) and in the sediment pore water where dissolved oxygen concentrations fall to zero. The nitrification and denitrification process is important in preserving the fishery in Indian Creek Reservoir in the Sierra Nevada mountains. This reservoir is fed by the tertiary effluent from the City of South Lake Tahoe sewage treatment plant. The effluent has at times contained 15 to 20 mg NH4 N/liter. Levels of ammonia of this magnitude are toxic to fish, yet in the reservoir there is a thriving fishery. This is achieved because the top waters of the lake nitrify the ammonia to nitrate and this is reduced to N2(g) by the anoxic bottom waters. The summer concentrations of nitrogen species of the reservoir are approximately 4 mg NOa -N/Iiter and 4 mg NH4-N/liter. 

Subtropical estuary designated as an aquatic preserve and Outstanding Florida Water bay comprises north, central, and south regions contains a coral reef system, which is the world s third longest and the only one in the world located in close proximity to a large highly urbanized coastal area reef is home to more than 200 marine species of fish and is important for fisheries...

Working together toward a more sustainable society includes responsibility, respect of natural resources (no farm and fisheries mining), conservation, preservation, and clever technological development. The three main pillars of sustainability are based on society, economics, and environment. Ray Anderson in his book Midcourse Correction Toward a Sustainable Enterprise The Interface Model defined three levels in the journey toward sustainability [23].
