Feeding Habits In Tilapia

918 Words4 Pages

The purpose of this study is to investigate the feeding habits and the type of food Oreochromis aureus prefers in a controlled and simulated environment. Feeding habits will be measured via feeding frequency and feeding rate and fish are given a diet of decayed aquatic leaves and zooplankton. Twenty juvenile Tilapia will be separated into two tanks and fed twice a day/three times a day over a thirty-day period, between the hours of 09:00-12:00. This study will use a qualitative data analysis (i.e. ANOVA and Tukey’s test) in order to measure variables and a top loading balance and standard length measuring board in order to evaluate the size of Tilapia. It is expected that weight gain and specific growth weight will significantly increase in …show more content…

Tilapia serve as the unit of analysis since their growth is being affected by feeding habits and food option.
Research Question/ Hypothesis
For the purpose of this study, the following questions were addressed:
1) When comparing the two food items, will zooplankton more significantly increase the size of Tilapia?

2) What influence will feed frequency and feeding habit have on Tilapia?
As part of this study, investigation included two research hypotheses:
1) The more mature Tilapia become, the more they will have a preference for the food item and, as a result, will increase in size.
2) The more feeding frequency increases, the more feeding habit will increase so their influence will be directly proportional.

There are many theories related to the history of aquaculture, which describes the farming of aquatic organisms (Phillips 2012). Over the years this process has commonly involved the use of intensive culturing systems. This began after the Blue Revolution in the 1950's as there was a great need for fish for consumption. Some theories that are related to aquaculture are the Oxbow, Catch-and-Hold, Concentration, and Trap-and–Crop theories. However, the only theory directly related to this study is the Catch-and-Hold theory that allows one to fish all year round. This particular method involves collecting fish that dwell in natural ponds or in the wild and rearing them in a more restricted area where they can easily be accessible (Phillips 2012). This is similar to the study on Tilapia since the species will be collected from a natural environment and placed in tanks so that they can be readily available when feeding and weighing are done. This restricted area also allows variables to be properly measured and findings less prone to

    Plankton Activity Postlab 1) Apply 2.5: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. Explain how the abundance of phytoplankton in the pond depends on the abundance of an abiotic resource such as nitrogen. - Phytoplankton are the producers in the pond. Species of organisms in ecosystems have their own carrying capacity relative to other species, and carrying capacities are determined by particular abiotic and biotic resources in an ecosystem. An increase in nitrogen levels in the pond (e.g. from fertilizers) will result in a dramatic increase in phytoplankton levels, but once phytoplankton population reaches its carrying capacity (determined by availability of other resources besides nitrogen, [DO] levels, predation etc.),

    The experiment consisted of two sub-experiments that when synthesized together, successfully answered our main question. The first of the two sub-experiments focused on collecting data for the creation of a life table in which Daphnia magna were not in the presence of a predator such as Lepomis macrochirus, known in laymen’s terms as bluegill fish. The second of the two sub-experiments focused on collecting data for the creation of a life table as well, but this time the daphnia were subjected to an environment where bluegill fish were present. The collection of the data for the creation of the first lifetable without predation consisted of fourteen replicates or daphnia starting at age 3 and ending at varying ages depending on the mortality of each replicate group.

    The experiment failed to reject the null hypothesis because there was no difference between two groups. The statistical analysis found that there was not a substantial enough difference between the high-density and low-density treatments to support the hypothesis that intraspecific competition would affect height and survivorship (Figures 1 & 2). We found that the low-density and high-density treatments were virtually the same and intraspecific competition did not affect height (t ratio=-2.04, DF=426, p-value= .021). For the survivorship variable, we also found that there was not a noteworthy difference in the results (t-ratio=-5.58, DF=458, p-value Functional Ecology Funct

    Students started off with a population of ten Skittlefish (skittles) on an orange reef (construction paper). The skittles had varying colors, and the adaptive trait being examined was the ability to blend in with the reef so the predators would not find them. The hypothesis that was thought up was that individuals’ survival was based on their location and coloring. The first year began with two of each color, and 5 Skittlefish were eaten that “year”. The ones eaten were two green, two purple, and one red.

    Brine Shrimps tend to hatch in specific environmental conditions, such as high and low salt concentrations in water, weather and temperature. As one of the environmental conditions in which Brine Shrimp eggs hatch is water salinity and so, in this assignment, we were given 4 different salinity levels of water, which were 0%, 3%, 6% and 9%. As a result of the experiment, we noted that after 24 hours only one egg hatched at 3% salinity level and none at 0%, 6% and 9% levels. The second day, which was after 48 hours, there were 0 shrimps that hatched in 0% and 9% salinity levels, whereas at 3%, 7 out of 46(15.3%) eggs hatched and 6 out of 49(11%) at 6% levels. Based on this data our group concluded that the best level for hatching shrimps is 3%

    Natural Selection Introduction: Natural Selection is the ability to survive and reproduce in a given environment. It is known due to evolution that has occurred over time and how mutation, migration, and genetic drift have changed. There is a variation in traits in animals, for example some birds have bigger beaks that can be used to feed on worms and bugs that are way underneath the river and lakes. Also there is a differential reproduction that occurs because not all animals can reproduce the same amount and there is a limit that the environment can support over time.

  • Asian Shore Crab Research Paper

    The feeding rates on the native blue muscle were compared, it was found that the Asian shore crabs had significantly higher feeding rates on the larger muscle classes, implying that they have a larger per capita impact on the prey population than the green crabs did (6). Although Asian shore crabs are known to primarily rely on plant material, they prefer mussels and other crustaceans, and have been known to deplete them. Even after a decrease in prey availability they are still able to maintain high densities. Evidence supports that when depletion of the preferred food source occurs the crabs turn to cannibalism because it is the best option energetically (7). This allows them to support high densities even when the preferred food source is gone or

    The first figure helped understand the location of the different tributaries in the upper Kiamichi River being used in the experiment. The first table helped highlight the point that the known range of O. saxatilis was shown to have increased and that the sympatric species P. tenius inhabits the same streams as O. saxatalis compared to the other sympatric species. Table 2 helped demonstrate that depth and flow velocity differed between riffles and pools especially between the dry and wet periods. This showed that the difference in water levels between riffles and pools could affect the habitat that the crayfish is living in and their preference for a certain environment. The other abiotic factors did not vary dramatically, which showed that they do not affect crayfish distribution.

  • Consequences Of Overfishing

    According to world wildlife organisation, overfishing occurs when more fish are caught than the population can replace through natural reproduction. Gathering as many fish as possible may seem like a profitable practice, but overfishing has serious consequences. The results may not only affect the balance of life in the oceans, but also the social and economic well-being of the coastal communities who depend on fish for their way of life. According to the research world wildlife organisation, 1.6% of the world’s oceans have been declared as marine protected areas (MPAS), and 90% of existing MPAS are open to fishing.
