project focus
Project Focus

Focus was on the Propagation of Parazoanthusgracilis (Yellow Colonial Anemone)

Wanted to examine most suitable conditions for the Yellow Colonial Anemone

After finding these conditions wanted to see how Yellow Colonial Anemone would do in more realistic environment

topic background
Topic Background

Generally found in shallow water on rocks

Moderate light

Moderate water current

Can be found in large and small numbers

Polyps are isolated from one another and don’t form encrusting mat

Polyps can send chemical messages to one another which explains why polyps open and close at the same time

Filter feeders but also have zooxanthelle

Reproduce by budding

Semi- aggressive

Do well in marine aquariums

research questions
Research Questions

Original Questions

Will there be a difference in growth between different corals based on amount of light?

If one colony of the coral is fed more frequently than another will that one grow as much as or more than the other?

If a coral were to be moved into a different tank would that affect the growth?

What is the success rate when propagating coral? Is it dependent on the type of coral?

hypothesis
Hypothesis

There will be an decrease in growth rate in the soft corals from tank A4 and B1 when light levels decrease but direct feeding levels remain the same.

Research did inspire hypothesis but focus changed

Began to focus on the Yellow Colonial Anemone rather than multiple types and project focus in the end was moved to competition between corals

research plan
Research Plan

Carried out research in tanks A4 and B1

Main organism Yellow Colonial Anemone from tank B1

Propagated Yellow Colonial Anemone using typical supplies

Placed propagated disc in different

Situations to see if growth rate was

Changed

Once determined different corals were

Placed to see how they would do in

Competition

data collection
Data Collection

In order to collect data and observe tank conditions daily notes were taken on both tanks

Daily checks were not necessary due to growth rate of Yellow Colonial Anemone even though it grows faster than most corals

During observations looked at growth rate of yellow colonial anemone propagated discs along with the growth on the front glass of tank B1

Later began observing interaction between corals that were placed on the same disc

question review
Question Review

Will there be a difference in growth between different corals based on amount of light?

Although specific question was not addressed research was still done on shading

Shading reduced growth rate in comparison to coral with light

If one colony of the coral is fed more frequently than another will that one grow as much as or more than the other?

Did not address question

question review1
Question Review

If a coral were to be moved into a different tank would that affect the growth?

Movement of Yellow colonial anemone had no affect on the coral and saw very quick growth even though it was in a different environment

Thought that new surroundings such as different coral, current and lighting would affect propagated disc

What is the success rate when propagating coral? Is it dependent on the type of coral?

Propagated five discs

Only had to redo one propagated disc because coral was very unsuccessful

data collection1
Data Collection

Number of Polyps Per Disc

final results
Final Results

Data involved with numbers in graphs

Data not seen in graph was not successful

Tried to examine competition between different corals

hypothesis reflection
Hypothesis Reflection

There will be an decrease in growth rate in the soft corals from tank A4 and B1 when light levels decrease but direct feeding levels remain the same.

Statement not researched in detail

Although research did support hypothesis

Not enough data for accurate support

challenges
Challenges

Had trouble with propagation

Time

Getting coral to interact

completing research
Completing Research

To make research more complete needed more time

Time would allow for interaction between corals and allow researcher to see how aggressive each coral would have truly been

Watch propagated disc in tank B1 for longer amount of time

Add more propagated discs to both tanks

data review
Data Review

Data matches up with expected results

Concepts tested are topics covered in our class so these results are seen frequently

Data could be used for other people interested in marine aquariums

Yellow Colonial Anemone is very popular in aquarium trade so selling colonies is an option

future of the project
Future of the Project

Most likely path would be to continue the research

Numbers are not very complete due lack of time

Different variations of competition could also take place
