(Rabah bar R. Huna): One may close off a pool of water before Yom Tov and take the fish found within it in the morning (they are considered designated).

(R. Chisda): From this teaching of Rav we may infer that the young of a Chayah which has made her home in one's Pardes may be taken with no specific Zimun.

(R. Nachman): Our Chaver, R. Chisda (or, the son of our Chaver, if it was Rabah bar R. Huna), by comparing the young of a Chayah to the fish in a pool, has stepped into a great Machlokes.

Question: One may readily differentiate between the two cases since he did designate the fish by the act of closing the pool, whereas he did nothing to designate the Chayah!?

Question: Furthermore, we were taught that a Chayah does require Zimun!

Answer: This refutes those who learn that a Chayah does not require Zimun.

Question: But a Beraisa establishes that (both Beis Shamai and Beis Hillel agree that) the Chayah (as opposed to a bird) does not require Zimun!?

Answer (R. Nachman): One Beraisa refers to the young (which does not require Zimun) and one refers to the mother (which does).

Question: But the mother should require more than Zimun, she needs to be trapped!?

Answer (Rav Nachman bar Yitzchak: Rather, one Beraisa speaks where the young is in a field close to residence (more Da'as) and one where the field is further (less Da'as).

One may not slaughter an animal unless there is time left on Yom Tov to eat a roasted k'Zayis of it.

(R. Akiva): Even if the time remaining is sufficient to eat a Kezayis from the place of Shechitah (without flaying the animal).

An animal slaughtered in the field may not be carried by two people but may be carried, by hand, limb by limb.

Gemara (Rami b. Aba): From the requirement of flaying and cutting an Olah we learn the Derech Eretz for butchers, as well, that one should not eat prior to flaying and cutting the animal.

Question: What is Rami b. Aba teaching us?

Answer: He is coming to differ with R. Huna (and to require Hefshet and Nituach to check the animal for Kashrus and not to rely on Chazakah).

Question: But the Mishnah supports R. Huna (as R. Akiva allows a k'Zayis from the place of Shechitah)!?

Answer: That refers to the place of digestion (and hence it is after Nituach, not before), not the actual place of Shechitah.

Question: But R. Chiya taught that it means the actual place of Shechitah!?

Answer: Rather, Rami b. Aba taught us proper conduct (not Halachos of Tereifos).

Similarly, the Beraisa teaches how to eat and drink.

Rami b. Aba also taught the moral lesson of certain vegetation (especially the Turmus).

(Cited in R. Meir's name): Torah was given (as antidote) to the fierce People, Israel.

(Tana d'vei R. Yishmael): It is fitting to give this People the Aish Das, alternately, the Torah is needed to counter the fiery nature of Israel.

(Resh Lakish): There are three fierce things...

A blind person may not go out with his staff nor a shepherd with his cloak.

One may not be carried on a chair.

Question: But we have a report that R. Yehoshua b. Levi permitted this if the community needs the person (and we rely on the reports of those who carried R. Huna and Mar Shmuel on their chairs)!?

Answer: Those were permitted, as stated, only because the community needed them.

Chama b. Ada asked this question of R. Zerika (having arrived in Tzur after the passing of R. Yakov b. Idi) who responded (citing R. Ami) that it is permitted, provided that the person is not borne on shoulders.

Question: What is meant by that?

Answer (Rav Yosef brei d'Rava): Alonki.

Question: But R. Nachman permitted Alonki?!

Answer: That was due to Yalsa's fear (as we find a similar dispensation by Ameimar and Mar Zutra due to fear or, due to the pressure of the crowd).
