QUESTIONS AND ANSWERS
1: What are the main extrinsic environmental factors that affect water quality of water entering
the Howietoun facility?
With the analysis of data which is related with the Howietoun facility, there are some well
determined extrinsic environment factor are being taken which may affect the water quality is
based on the quality provide basic scientific information about water quality water parameter and
ecologically which is show relevance toxicological threshold value which is helpful to protect the
specific. The data show a number of factor which include sedimentation, runoff, erosion,
dissolved oxygen, pH, temperature, decay organic material, pesticides, toxic and hazardous
substance, oil, grease and other chemical, detergents and so on are extrinsic factor which may
affect the water quality (Adeboye and et. al., 2017).
2: What are the key environmental wastes put into water from the salmon smolt unit?
Salmon farming is defined as the wreaking ruin and marine ecosystem which is through the
pollution, parasite and the high fish mortality rate which can cause damage of pond or the aspect
of fishery. As per this, the wide assessment is identified which is about the global salmon
farming industry which has been found. Moreover, the sheer quantity of wild fish in the salmon
is also going to be used with the matter of concern. Usually, there are three type of waste which
is include blood water and brine from the drained, water discharge from the washing and scrap of
flesh, blood and soluble.
3: How has the water quality varied within the catchment and aquaculture facilities between
2014 and 2016 (see the data provided in the spreadsheet). Use graphs to show the and
explain these differences. Why do you think the levels vary with time and the location of
the samples?
While analysing the data that us related with the water quality among catchment and aquaculture
shows that the nitrate, ammonia, phosphate and alkalinity is minimum during the 2014 and in
2016 the chemical factor are enhanced. So, the major reason of varying water quality from the
2014 and 2016 is due to increase chemical in the water which may turn the nature of water in
1

2016 is more acidic and while in 2014. It is compatible for the fishing is easier way at 2014.
As per the analysis of data, from the 2014 and 2016 the change is derived which is based on
chemical which is change as per the time which can reduce the quality of water from the 2014 to
2016. The current water quality as per the data is so much acidic and it is difficult to maintain the
buffer for the fishery (Bjørndal and et. al., 2019).
4: Comment on the biological results from the Fishery using the kick sample data from the
stream, the benthic data from the ponds and the plankton data from the ponds (see
spreadsheet). Do they change over time? Are there indications of any environmental
impact? You should calculate the BMWP scores for the kick sample results as they this
will give you an idea of the environmental quality. See BMWP information
As per this, organic result from the fishery using the kick sample which is based on stream which
show that in 2015 the K3 outflow of species include Hirudinaea species, Gammaridae,
Sphaeriidae, Coleoptera, Trichoptera, Cladocera and many more species which is related with
water bodies are prenset are in low number during the year 2015 but they increase their growth in
2

2016 with the K3 outflow. Moreover, the benthic region of the ocean begins with the shore line
which is called as intertidal or littoral zone which used to extend downwards along the surface of
the continental shelf that out of sea or pond. The major of continental shelf is usually in form of
sloping benthic which used to extend away from the mass of land. At the matter of continental
shelf edge which is usually about the 200-metre-deep moreover, the gradient is enhance and it is
known as the continental slope. Moreover, deep sea floor is referring as the abyssal plain which
is usually about 4,000 metre and more. They change as according to time when the species are
used to reproduce themselves then may be the environment get impact which is analyse as per
the pond benthic where the data drive that in 2015 as an example the nematode have 50 in B3
and in 2016 the number is enhanced up to more than 1000.
The score of BMWP that called biological monitoring working party is good due the number of
rise between 71 to 100 which indicate clean but slightly impacted.
5: Based on the water quality results from the catchment and aquaculture facilities Do you
consider the quality of the water to be suitable for fish welfare and effective growth? Why?
As per this, the quality of water is appropriate for the fish welfare and for the actual development
because as per the data the oxygen is good enough in the pond and if the catchment is up to
enhance and it show that capacity have annual rainfall which is measure in millimetre is enough
with into with roof surface are which is measure in square meter show the outcome of roof
catchment capacity (Cohen and et. al., 2018).
6: Explain if you think there will be any environmental issues as a result of the water quality of
the outputs from the aquaculture facilities?
With the major concern, it is analysing that the environmental effect which may create poor
water quality include health risk to farm the worker from water borne disease which include
schistosomiasis and salinization or the acidification of soil and aquifers. This is also possible that
the presence of mental which have high atomic weight from the livestock feeds in integrated
aquaculture which is usually accumulate in fish and pond sediment.

7: Using the information given about the SEPA discharge consent in the presentation, comment
on whether you think the Howietoun fish farms conform to environmental regulatory
standards
With this aspect the standard guideline with the SEPA discharge consent in the presentation
which is detail data of Howietoun fish farm is follow environmental regulatory because the pH
that indicated in Howietoun is 5 to 9 and standard guideline show 6.5 to 9.0. As per this, they
also follow standard regulation such as have suspended solid level of release not surpass that of
the consumption aquatic by more than 5 mg/l and ammoniacal nitrogen contented in discharge
must do not exceed the inlet water which is more than 0.5mg/l. This all are coming the
Environmental regulatory standard and deviation are occurring which is accepted only one-time
failure in a year (Forchino and et. al., 2017).
8: Are the discharge consent criteria, in your view, suitable for assessing the environmental
impacts of the fish farm? How would you improve on these?
To improve the discharge consent are in way to assess the environmental impact of the fish farm
by encourage sustainable fisheries management, and try to implement catch construction and
aquaculture. With this all reduce and minimise the illegal fishing through the catch
documentation (Stoeck and et. al., 2018).
9: What measures would you recommend in order to improve environmental conditions at the
Howietoun fish farms?
There is some recommendation which helpful to improve the environmental condition which is
associated with the fish farms are:
 Choosing of right species which indicate that the invasive species related with non-native
are such plant and animals which is do not obviously occur in an exact location and they
can spread easily which is native in resource. These can finally overtake and substitute
native species or cross with them. With fish, it is highly flexible tilapia moving native
pond species diagonally the tropics.
 In this, the other factor which may render the fish farming is pollution so, fewer
pollution, high excellence of food results in the better growth rate and improved health
4

enhance the farm performance. In this, by sticking with good feeding practice, the over
waste can be reducing and maintaining of excellence plus the fitness of farmed fish can
be enhanced (Hoga and et. al., 2018).
10: In your opinion, is Howietoun fish farm situated in an appropriate location for aquaculture?
Why?
In my context, the Howientoun fish farmhouse is situated in appropriate site because aimed at the
proper farming of fish. the site is away from the flood area. In this, water is not much acidic or
alkaline and if it is, then correction is being done while applying lime and organic manure. The
ideal temperature which for the fish farming is 20 to 30 degree Celsius. Water salinity is the
amount of salt which is dissolve in water (Neofitou and et. al., 2019).
