Final weight of romaine lettuce was Organic waste from the cultivation of gouramy can be processed with phytoremediation by romaine lettuce. Organic materials such as feed residuals and feces after the process of decomposition can be utilized for romaine lettuce growth. However, the best feed conversion ratio FCR was P3 aquaponics with 20 romaine lettuce of 0.
Minimizing Fishery resources in waters either marine or inland the use of water will furtherreduce the impact on waters have been intensively exploited. To support the environment, hence, production of aquaculture the availability of animal protein, aquaculture can be maximized.
One effort that can be applied is activities arerapidly growing around the world. Along with the increasing aquaculture Aquaponics system is the combination of activities, the negative impact on the environment aquaculture with hydroponic plant in the also emerged, such as increasing accumulation of recirculation system Diver, ; Rakocy et al.
Accumulation of waste derived ; Endut et al. According survival. According to Endut et al. Plant used in aquaponics systems is not only aquaponics and hydroponics. Aquaponics system aquatic plant but also horticultural crop was designed using an 80 x 40 x 40 cm aquarium vegetable which is quick to harvest, for example and filled with L water.
Installation system tomato and lettuce. This statement is supported by worked by recirculation process. The water from the previous study conducted by Graber et al. The water then flowed water with vegetable production, while improving from the gutters and was collected in a tank. The water quality of fish growing medium.
One of water was then pumped back vertically into the vegetables used in the study is tomato. In a study aquarium. Hydroponic installation out by integrated aquaponics system using lettuce system worked with recirculation system, but plants. Plant used in this research was romaine lettuce, In the hydroponic system, water came from a a variety of lettuce Lactuca sativa L. Water from the gutterswas collected with pests than fruity plants. It has low to medium in the water tank and then pumped back vertically nutritional needs and can be customized with to the hydroponics gutter.
Romaine lettuce is a vegetable that is favored because of its aroma Gouramy introduction in aquaponic and crispiness Llorach et al. Fish were processed comes from gouramy Osphronemus acclimatized for one week so that the nutrients goramy cultivation. Gouramy is a superior were accumulated to provide nutrients for lettuce. The frequency of feeding was high prices Azrita and Syandri, Therefore, three times a day. Measurement of the length and aims of this study were to process organic waste weight was conducted every week.
Each pot which was This research was conducted in Center for planted by lettuce used rockwool as growing Environmental Research, Bogor Agricultural media except the control treatment. The water quality analysis was was conducted one week after the fish were put conducted in the laboratory of Aquatic Producti- into the aquarium.
Nutrition was Experimental design only derived from the cultivation of gouramy waste. Plant height, leaf width and the g and wet weights at time t g , while t0 and t number of leaves were measured every week, were the initial time of observation day and while weights were measured at the beginning and observation time at t days. Water quality measurement Water quality parameters consisted of physical Description: W0 and Wt were the initial wet weight parameters such as: temperature, turbidity and g and wet weights at time t g , while t 0 and t chemical parameters included: pH, dissolved were the initial time of observation day and oxygen, TAN, nitrate, nitrite, and orthophosphate.
Sampling and observations were conducted every week for 35 days, and then analyzed in the laboratory using a method published by APHA Description: N 0 and Ntwere the initial number of Gouramy and romain lettuce growth individuals g and the number of individuals at time t g.
Observations of lettuce growth included weighing the initial and final of experiment weight and measurements of plant height and number of leaves. Calculation of daily high growth rate DGR of lettuce was obtained by the formula proposed by Description: W 0 and the Wt were the initial wet Ridha and Cruz, Water Quality The average value of the temperature in each treatment was relatively not much different from Description: W0 and Wt were the initial wet weight Turbidity in each treatment fluctuated in the observation time at t days.
During the observation Length and weight of fish were measured by period pH values ranged from 5. Daily growth rate ment with high ammonia input such as aquacul- GR , specific growth rate SGR , survival survival ture wastewater, biooxydation of this compound rate were obtained from formula proposed by produces CO2 and lowers pH.
Zonneveld et al. Nitrate levels in the observation Description: W0 and Wt were the initial wet weight period was very fluctuating.
It occured RGR , weight gain and number of leaves. However, both treatments needed by plants in large amounts. High nitrite levels in P1, P2, Descriptively, final weight in P2 and P3 did not and P3 were supplied from the decomposition of much differ, ranged from 85 to High higher final weight than P2 and P3. Meanwhile, the levels of nitrites could be a problem for fish. The average final weight of romaine to break down the organic material into a source of lettuce P2, P3 and P4 were better when compared nutrients needed by romaine lettuce growth.
In this study, nitrite levels could be tolerated gravel, and control. Meanwhile, the study by fish, so that gouramy could still grow well. High levels of was Powerful and efficient filtration is essential as these are exceptionally messy fish.
Omnivorous and unfussy. In the wild it will also eat amphibians and sometimes dead animals! Will eat smaller fish but is generally peaceful with other large fish. Some adults may become very aggressive but this is often due to being kept in an aquarium that is too small. Given plenty of room, this fish will usually coexist with tankmates such as knifefish, large catfish and loricariids.
The male develops pointed dorsal and anal fins. Relatively easy but a truly huge tank is required to breed fully grown adults. This species is sexually mature from 6 months, so it is more realistic to use young fish for breeding purposes. Surface vegetation must be provided. The male builds a large nest out of vegetation including grasses and roots in nature. Spawning occurs in the vicinity of the nest and the eggs are transported there by the male.
Osphronemus goramy Short profile Summary Short profile. FishEthoBase is focussing on behaviour Fish welfare depends on 3 types of factors: physiological, behavioural, and mental factors. Short profile: A sharp assessment of the welfare state and potential of a species With the short profiles, we pursue two goals: To carry out a rapid evaluation of welfare of farmed fish by focussing on 10 crucial criteria, in order to cover ultimately all fish species farmed nowadays ca The short profiles aim to complement rather than replace the much deeper and laborious full profiles which will be continued in parallel.
Short profile rationale download as pdf. Short profile. FishEthoScore of the species Abbreviated assessment of the species' likelihood and potential for fish welfare in aquaculture, based on ethological findings for 10 crucial criteria.
Criteria Li Po Ce 1 Home range? General remarks Osphronemus goramy of the family Osphronemidae is originally living in freshwater bodies of Southeast Asia. Are minimal farming conditions likely to provide the home range of the species?
What overall welfare potential can be achieved? How certain are these findings? Are minimal farming conditions likely to provide the depth range of the species? Are minimal farming conditions compatible with the migrating or habitat-changing behaviour of the species?
Is the species likely to reproduce in captivity without manipulation? Is the aggregation imposed by minimal farming conditions likely to be compatible with the natural behaviour of the species? Is the species likely to be non-aggressive and non-territorial? Are minimal farming conditions likely to match the natural substrate and shelter needs of the species?
Are minimal farming conditions handling, confinement etc. Are malformations of this species likely to be rare under farming conditions?
Is a humane slaughter protocol likely to be applied under minimal farming conditions?
