Fish. The most recent Peel River fish contaminants study was done in 1999. This study was carried out due to continued concerns from Fort XxXxxxxxx residents regarding the safety of eating fish from the Peel River. The concerns were related to an abandoned Shell oil exploration site and possible point source of contaminants upstream on the Peel River near the Peel/Caribou River confluence. A total of 30 fish, including ten each of inconnu (Stenodus leucichthys), broad whitefish (Coregonus nasus) and burbot (Xxxx xxxx), were examined for a suite of heavy metals and organochlorines. Local fishermen at traditional fishing sites captured all fish. Based on the results of the study, the three fish species from the Peel River were deemed safe for human consumption. No further studies were recommended at that time.
Fish. Handling and transport associated with reintroduction, translocation, or monitoring activities are expected to result in temporary physiological stress and altered behavior on individual fish. This effect is expected to dissipate shortly after release. Changes in temperature, turbidity and surroundings of the natural environment may also result in physiological and behavioral stress. Feeding behaviors are not expected to be significantly affected and covered fish species are anticipated to forage in both the artificial and natural environments. After some time, it is expected that the covered fish species will recover from any short-term physiological and behavioral effects and adapt to the new surroundings. Monitoring activities include mostly actions by KDWP to measure the condition of covered fish species habitat and populations status on enrolled lands. Some of these activities may result in take of covered fish species, but such take is anticipated to be minimal and the monitoring is necessary to determine the effectiveness of the reintroduction. Examples of monitoring activities include the following. • Capture and handling of covered fish species by various techniques, including trapping, netting, electrofishing, and angling. • Tagging of covered fish species to measure survival and movement. • Measurement of aquatic physical habitat, including, but not limited to, channel cross sections, habitat unit mapping, riparian zone surveys, and stream temperatures. • Ongoing operation of flow-monitoring devices. Habitat management actions or land use activities in streamside habitats may cause individual fish to disperse away from the activity locations. Such disturbance to individuals is likely to be temporary and, thus, will not likely adversely affect the feeding, breeding, or sheltering of these fish. Reintroduction and monitoring have the potential to result in the injury or mortality of individuals. Estimated incidental take is expected to be less than 1% of the reintroduced population. Any impacts from incidental take would be outweighed by the expected benefits to the local or regional population from reintroduction and habitat management actions.

Care must be taken to avoid their reproducing. The animals must be enclosed in an acceptable cage at all times. They must have any or all inoculations as specified now or in the future by State law or local ordinance. Turtles Residents may have only 2 turtles, which must be enclosed in an acceptable cage or container at all times. MHA does not allow pot-bellied pigs, iguanas, snakes, alligators, or any other animal not specifically listed above. Application Prior to housing any pet on premises owned and/or operated by the Housing Authority. A tenant shall apply to the MHA for a permit to do so. The application must be accompanied by the following:
Fish. Fish were collected at each habitat site in late summer or early autumn of 1998-2003. Fish community data has been analyzed for 1998-2002, and samples collected in 2003 are currently being processed. Species richness, abundance, percent composition, and Index of Biotic Integrity scores are being used to assess the responses of fish assemblages to BMPs. From 1998- 2003, boney structures (i.e. scales, fin rays, otoliths of selected fish species were collected) to evaluate age structure and growth rates. Determinating fish growth rates is ongoing and growth data from largemouth bass, bluegill, green sunfish, and longear sunfish from 1998-2001 have been analyzed. Growth rates and age structure of white sucker, yellow bullhead, and creek chub is currently being analyzed and assessed.

Fish. Fish tanks may NOT exceed 15 gallons and must be placed in a safe location in the dwelling unit.
Fish. The fish found in the Landmark are similar to the Tuktoyaktuk harbour area. The shallow waters of the bays and coastal areas support a variety of fish species such as Pacific xxxxxxx, rctic cisco, least cisco, burbot, broad whitefish, and inconnu.
Fish. The intestinal bacteria and viruses of humans do not cause disease in fish but they may be passively transferred to humans by fish. Water-based helminths parasitic to humans may be transmitted by fish which act as worm intermediate hosts, for instance, liver flukes (Xxxxxxx, 1992). Bacteriological examinations of fish cultured at wastewater-fed marine ponds revealed significant numbers of Enterobacteriaceae in the digestive tracts, although none were found in samples of kidney, liver and spleen (Xxxxxxx, 1992). Seaweeds No information seems available on the risk for diseases by seaweed consumption as a result of bacteria and viruses. There are two reasons which reduce potential risks: Seaweed are always washed prior to consumption ( washing off potential bacteria such as Vibrio’s); Seaweed seem to have antimicrobial compounds, which may lead to less bacteria. Food safety criteria Commission Regulation (EC) No 2073/2005 on microbiological criteria for foods (EC, 2005) lays down food safety criteria for relevant foodborne bacteria, their toxins and metabolites, such as Salmonella, Listeria monocytogenes, Enterobacter sakazakii, staphylococcal enterotoxins and histamine in specific foods. These criteria are applicable to products placed on the market and define the acceptability of a product or a batch of food. The activities performed to ensure the application of food and feed law are laid down in Regulation (EU) 2017/625 (EC, 2017a). Besides the safety standards in food, microbial quality targets have been established for the environment that can be used to facilitate compliance with the health-based targets, e.g., viable trematode eggs not detectable (number per 100 ml or per g total solids, or ≤ 104 E. coli (arithmetic mean number per 100 ml or per g total solids) and ≤ 1 helminth egg (arithmetic mean number per litre or per g total solids) in aquaculture water to protect consumers (Xxxxxxx, 2008).
Fish. Fish catch-per-unit-effort (CPUE) by numbers and biomass and the contribution of omnivores have been recommended as fish metrics for Water Framework Directive (WFD) assessments. These metrics all seem sensitive to nutrient loading reduction. • Climate change may in part counteract the response to nutrient loading reduction. Changes in fish assemblage composition, size and age structure during the last decades are profound. A cross system analysis of long time series of fish assemblages in European lakes indicates a decline in cold-stenothermal species, in particular in shallow lakes, an increase in eurythermal species even in deep, stratified lakes, and a decrease in the average size of the dominant species xxxxx (Rutilus rutilus L.) and perch (Perca fluviatilis L.). This development has occurred despite an overall reduction in nutrient loading that should have favoured fish typically inhabiting cold-water low nutrient lakes and larger-sized individuals. • Warming will result in a fish-mediated increase in eutrophication that will partly counteract the effect of nutrient loading reduction. This implies that it will be more difficult to obtain the good ecological status required by the WFD in lakes facing climate warming. Zooplankton • Zooplankton and cladoceran remains in the sediment are important and cost-efficient indicators of the pressures, structure and function of freshwater lake ecosystems and their ecological status. • Zooplankton size structure, proportion of large zooplankton, cladoceran size and the zooplankton:phytoplankton biomass ratio are suitable indicators of top-down processes in lakes. • Zooplankton biomass, the proportion of rotifers by numbers and the proportion of calanoid copepods by biomass are important indicators of bottom-up processes. • Combination of top-down and bottom-up indicator metrics might yield a solid assessment of trophic conditions in the pelagic of lakes. • It is strongly recommended that the EU includes zooplankton and cladoceran remains in the surface sediment as central BQEs in the WFD assessments in the future. Phytoplankton • Phytoplankton biomass (and chlorophyll a) responds to nutrient loading reduction triggering a shift in the relative contribution of eutrophication indicators, such as cyanobacteria and green algae, towards indicators of lower trophic state. • Genera evenness also responds to nutrient loading reduction, although the direction of changes varies among lakes and year to year variability is hi...
