- Pond B Pond C Figure 3. Representation of three experimental ponds located in the Hagen Aqualab at the University of Guelph. Ponds have one or both of two fish species: Stripey- Orange Clownfish and Black Herring. All ponds have been kept at 20°C for many years and contain large and small worms as food. For each statement, select TRUE if it is consistent, or FALSE if it is not consistent with the information presented above. True Felco If we add 3 Black Herring to Pond A and over time the number of Black Herring returns to 2, then the carrying capacity of Black Herring in Pond A is 5.Questions 1 What was the impact of overfishing on the community of fishers?

- ANSWER THE FOLLOWING: If you are to engage into aquaculture, how will you do it considering your current location and available resources. What species, level of management and culture system will you consider? (imagine your location is Philippines) On the otherhand, if all resources are available and favorable, what brackishwater and marine species will you grow/culture? Discuss your criteria of considering these species. Describe the level of management and culture system that you will employ.Please help me answer this in 10 sentences only. In the Convention of Biological Diversity (CBD), the precautionary principle read “when there is a threat of significant reduction or loss of biological diversity, lack of full scientific uncertainty should not be used as a reason for postponing measure to minimize or avoid threat”. What is the application of this principle to straddling fish stocks and migratory fishes?

How does the law of tolerance affect where populations of organisms live? Organisms are not affected by the law of tolerance. Organisms tolerate the water conditions but cannot tolerate other abiotic factors. Organisms only live where they can tolerate the conditions. Organisms live where they can tolerate the other organisms.
