Stenopus Hispidus Joe and Brendan

Hypothesis The breeding of the Stenopus Hispidus or the Coral Banded Shrimp is a difficult process that needs perfection of variables that include, the correct type of food along side with the correct amount of food, and a multitude of different living variables to successfully hatch the larvae.

Background The Stenopus hispidus shrimp live in the indo-pacific region region from the Red Sea and South Africa to the Hawaiian and Tuamotu Islands. Live in low turbulent water. The coral banded shrimp is a very well known crustacean in the marine world being one of the most distributed marine organisms bringing in almost 200 million dollars a year Boxing shrimp Mate for life

Focus The focus of our research was originally to catch and raise the coral banded shrimps larvae. After the female shrimp was pregnant and we missed our opportunity we realized that the behaviors of the shrimp changed drastically. While the female was pregnant we saw changes in the male's life and noticed that he became more active, and the female stayed basically in one place the entire time. These observations are beneficial to understanding when the female is pregnant without even seeing her eggs.

Research Questions What would be a average survival rate of the larvae? If the larvae does survive what is the next step in establishing them in their own tank or back in the original tank? What changed between the two shrimp when the female was pregnant? Did their locations in the tank change when the female was pregnant?

Methods and Research Step 1: Locate and Identify female Step 2: Do tank tests and make sure tank levels are safe Step 4: Make observations on the tank daily to notice any change with the female Step 5: If female is pregnant add larvae catcher

Results Mating time We were never successful in catching and raising the shrimp larvae.

Data Table 1 Pregnancy Pregnancy

Location Data Table 2 Date

What we did right Identification of female pregnancy Data collection supporting female pregnancy Recognizing behavioral patterns Kept up to date on checking tank and organisms.

Challenges Timing Catching and raising larvae

What would we do differently? Check tanks more often Once we noticed the shrimp was carrying eggs put the larvae catcher in Make sure we have enough time

Big picture We noticed that when the female shrimp was carrying eggs the male changed its habits and was more active in the tank, which made it seem like he was doing things, such as gathering food, for the female while she was pregnant The importance of knowing how these patterns change is important in the reproduction of the shrimp because you can be more prepared for the release of larvae It is very hard to successfully breed and raise coral banded shrimp in any artificial environment.

If we were to continue Note the shrimps habits once again Prepare a larvae catcher Attempt to raise larvae and observe them

Reflection Our hypothesis changed from what it originally was at the end of the year. We went from wanting to catch and raise coral banded shrimp larvae, to understanding the changes in male and female life when the female is pregnant and carrying eggs. We started noticing these changes before the females eggs were completely visible by us.

Conclusion In conclusion we found that the shrimp carried her eggs for approximately two and a half weeks.
