Final Flashcards
what is health surveillance?
set of planned measures in a hunting ground
what are the goals of health surveillance?
- recognise the risk of a disease, its occurrence and possibility to spread over
what are the basic components of health surveillance
coprological exams
PM exams
quarantine measures
what is the most common cause for morbidity and mortality of game species?
parasitic disease
what should partial necropsy follow?
sanitary and harvesting culling
two type of measures in health surveillance
preventive:
- understand the situation which needs implementing of preventative measures at the high risk area
corrective:
- implementation of targeted therapy
- speeding up transportation of game
- reducing time required to implement quarantine measures
- reliable relocation of game
methods of implementation of health surveillance
- collecting data about game (species and number)
- collecting about hunting ground
- abundance of certain game species
- collect about epizootiological situation
- collect specimens of faeces
- implement quarantine measures
- collect samples for diagnostic test
- assessment of stress levels
- necropsy of carcass
- inspection of slaughterhouse
coprological monitoring
- carried out in 2 ways: either joint sample or individual sample
- collection at selected locations
- faeces are collected at game gathering places
- should be fresh. required number is relative to size/number of population
- should represent at least 40% of population
- collected in special plastic containers
- individual sample should be taken twice a year (spring and autumn)
stress level assessment
- major problem with stress, is decreasing immune system and making them susceptible to disease
- done by taking faeces and testing level of cortisol metabolite in faeces
- frozen straight away to prevent further degradation
- immunoenzymatic assay
necropsy
- carry out as many as possible
- dead game is rarely found that is suitable so often based on sanitary and harvesting culling
- prior to necropsy check for either anthrax or rabies
- field necropsy - only be county vet
- wear protective clothing and researcher should have rabies vaccine
advantages of health surveillance
- know the cause of the mortality of morbidity
- prevent critical moments
- safer procedure for handling and transportation
- cheapest prophylaxis
- improving health and quality of game population
field work - health surveillance
- it’s necessary to visit the hunting ground
- need map of ground with drawn positions
- all objects should be marked with numbers
- introduce the members of the society and explain:
> the purpose of it
> what’s the reasonable time window
> who need to do what
> individual and total cost and method of reporting - need to do final report with opinion and advice
sample collection and delivery
- maximum caution is required during sampling
- when rabies suspected:
> small - whole corpse sent
> large - only head, in airtight containers - blood samples be taken in pre-prepared tubes
- samples accompanied by a cover letter
- samples sent by courier, hygiene service deliver or in person
hygiene and sanitary measures
set of measures with a preventive purpose in order to protect wildlife/domestic animals/humans
- partial sanitary culling
- reducing culling of overabundant predaotrs
- removal of stray dogs and cats
- harmless carcass removal
- reclamation measures
- disinfection, disinsection and pest control
sanitary culling
- measure by which game animals with visible signs of disease are excluded from further breeding
- measure is justified only in case if no medical treatment is possible/ not achieve healing
- 2 levels of implementation: single (non expert) or total (vet authorities)
- advantages of sanitary culling is it completely eliminates sick animals and helps to find the cause
- disadvantage, is changes in behaviour doesn’t mean sanitary culling is needed
- single sanitary culling if curing isn’t possible
- total = cannot be avoided in case of severe or highly contagious disease
- hunt rights holder is obliged to report each culling with certificate and proof of disease
first detection of the disease
- easiest and most unreliable is observation and visual assessment but it’s the first step in game animals
- observed from observation points at high seats
- look for thinness, blood, deformities, bad hair coat, etc
- sudden death of large number = infectious disease or poisoning
- reduce the overabundant predator
- remove stray dogs and cats
harmless carcass removal
- to prevent the spread of pathogens
- collect carcass and eliminated the infection or to determine the cause of death
- shipped to incineration plants or necropsy
burying
- simplest way to bury is make it deep enough that animals cannot reach
- should be poured with lime for disinfection purposes
- surface of soil that animal was lying on, also buried
- drained terrain
- pour on with non-slaked/quick lime
- minimum of surface soil layer is 0.5m
- small game at finding site
burning
- depending on season and potential risk of forest fire
- dig a shallow pit
- fold the combustible material
- put on the corpse
- wait until combustion is completed
- bury the pit
disinfection, disinfection and pest control (DDPC)
- for fenced game breeding, it’s important
- PC for forest company to protect oak saplings
- PC by agricultural company to protect crops
- at management facilities
- PC doesn’t eliminate all rodents
- advisable to undergo microbiological and serological monitoring twice a year
- game management practice use fenced hunting grounds….
hunting ground maintenance
activities that are carried out for purpose of improving living conditions, breeding and protection of game speceis
cleaning forest roads + hunting trails
planting woods
sowing of grass mixtures
sowing of cereals
construction of management facilities
management facilities
feeding spots
artificial water sources
salt spots
food storages
collection and wintering centres
fences and bridges
game jump in and out facilities
hunting lodges and huts
hunting (technical) facilities
watchers (observation posts)
hunting stands (shooting posts)
entrenchments (hidden posts)
traps (catch posts)
mess systems
hunting act
- damages shall be the responsibility of hunting rights holder
- hunting rights holder is obliged to take measures to prevent damage that the game can cause same as land users
measures for preventing damages caused by the game
establish and maintain of hunting management capacity (SGC)
- ensuring sufficient food and water
- expulsion of game from endangered land
- use protective measures: fences, electric shepherd,
damages to game
natural calamities: fires, floods, harsh winters, predators, diseases
antrhopogenic influence: poaching, poisoning…
direct: freezing, sub cooling, leg injuries, drowning
indirect: weakening, susceptibility to predators and poachers, inability to eat
birds of prey
impact on the natural breeding process of small game
protected species: hawk, eagle, falcon
furry predators: golden coyote, red fox, Martens, brown bear, wolf, lynx
crime scene
- check landscape appearance, vegetation…
- exclude other causes of mortality
- signs of Predators presence (footprints, etc)
- signs of predator attack (blood on ground)
- method of killing prey
- bear usually opens prey in abdomen/chest, head and body usually in unusual position
- red fox, have small sharp teeth so looks like small shots
game protection measures
- closed season for all game species
- temp hunting restriction
- pest reduction
- preventive health measures
- rescue animals during disasters
definition of wildlife management
sustain their populations and habitats over time, taking into account the socioeconomic needs of human populations and habitats over time
goal of wildlife management
to preserve biodiversity in coexistence with humans
- monitoring: brown bear mortality
- identifying problems: ration of hunted males and females
- action plan: weight limit
population monitoring
distribution
population size
mortality
breeding
genetic diversity
nutrition
movements and activity
health status
methodology
direct: observation, capturing, mortality
indirect: signs of presence (tracks, feces, vocalisation), phototraps
population size estimation
population density
trend
total count/census
incomplete count
capture recapture
negative environmental impacts on brown hare farming
constant use and increasing amount of applied mechanisation, fertilisers and pesticides in agriculture causes irreparable changes in natural habitats of brown hare
species characteristics of brown hare farming
- remarkable fertility
- rapid growth
- timidity
- susceptibility to disease and stress
cage breeding technology for brown hare
farm
- cage for adult couple (feeder, female and male section)
- cage for young
- cage has solid rear part and wire outlet
cage for adult couples
- priority (reproduction, feeding)
- cages for young
- adaptation
- capture and transport
cage types
- Italian type (oversized) with barrier in form of septum
- galvanised thin sheet cage
- construction error - plain wood planks
reproduction of brown hare
special attention of: exterior, health, body condition, temperament and productive properties of ancestors
if breeding pair is acquired from other farm/directly from nature quarantine of 30 days is requires
female fertile at 4-6 months of age
pairs are in reproductive function 3-4 years, but best is 2nd and 3rd
sex determination
mating of hares in cages starts naturally in second 1/2 of jan
1st litter = march/late feb, last in sep, then reproductive rest
average 5-7 litters per year
- young hares spend 23 days with their parents
- after 1st 2 weeks, start solid food intake
- after 23 days, removed and houses in cages for young hares
- 70 days, moved into the polygon for adaptation
adaptation of brown hare
- performed at farm location or in hunting area
- terrain of polygon must be dry, with quality grass cover and covered by protective net
- inside: feeding and fresh water
- natural instincts last minimum 7-10days (self preservation) after that, they’re caught and transported
daily monitoring is required due to entry of predators
capture and transport of brown hare
- after netting capture, they’re placed in transport boxes, which should provide: enough space, sense of safety and good ventilation
- bottom of box mustn’t be slippery
- boxes must be sturdy and made of waterproof material
why would you capture?
research
medical treatment
transport
what is used as baits
food
