It looks to me like it would be a strange reading, that Paul meant only fish. He uses the words πᾶν and πλήρωμα
πᾶν τὸ ἐν μακέλλῳ πωλούμενον ἐσθίετε μηδὲν ἀνακρίνοντες διὰ τὴν συνείδησιν, τοῦ κυρίου γὰρ ἡ γῆ καὶ τὸ πλήρωμα αὐτῆς.

Did I speak of a reading or of logic and a way of thinking?
These passages look to me like outright permission:
But give that which is within as a charitable gift, and then all things are clean for you.

Now food will not bring us close to God; we are neither the worse if we do not eat, nor the better if we do eat.

1 Cor 8:9-13 KJV - 1 Cor 9:1-10 KJV
9 But take heed lest by any means this liberty of yours become a stumblingblock to them that are weak.
10 For if any man see thee which hast knowledge sit at meat in the idol's temple, shall not the conscience of him which is weak be emboldened to eat those things which are offered to idols;
11 And through thy knowledge shall the weak brother perish, for whom Christ died?
12 But when ye sin so against the brethren, and wound their weak conscience, ye sin against Christ.
13 Wherefore, if meat
[G1033 broma] make my brother to offend, I will eat no flesh
[G2907 kreas] while the world standeth, lest I make my brother to offend.
1 Am I not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord?
2 If I be not an apostle unto others, yet doubtless I am to you: for the seal of mine apostleship are ye in the Lord.
3 Mine answer to them that do examine me is this,
4 Have we not power to eat and to drink?
5 Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas?
6 Or I only and Barnabas, have not we power to forbear working?
7 Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock?
8 Say I these things as a man? or saith not the law the same also?
9 For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. Doth God take care for oxen?
10 Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope.
In the LXX version of the Torah, βρωμα is general, food, and it is anything having been declared to be food for eating. κρεας is animal flesh, but as far as eating it is of course mentioned only concerning the flesh of clean animals and the sacrificial offerings in the Torah. Paul only mentions κρεας twice, and in both of these instances he places κρεας in a very negative light, and we have the one occasion mentioned above, where he says:
1 Corinthians 8:13 T/R
13 διοπερ ει βρωμα σκανδαλιζει τον αδελφον μου ου μη φαγω κρεα εις τον αιωνα ινα μη τον αδελφον μου σκανδαλισω
Wherefore, if
food (βρωμα) causes my brother to stumble, absolutely not (ου μη) will I ever eat
flesh, (κρεας), lest I cause my brother to stumble.
The other place where Paul uses κρεας is Romans 14:21, and it is really the same contextual material as in the above passage, and it closes with the same negative stance against κρεας, which again is animal flesh.
Romans 14:13-21 KJV
13
Let us not therefore judge one another any more:
but judge this rather,
that no man put a stumblingblock or an occasion to fall in his brother's way.
14 I know, and am persuaded by the Lord Jesus, that there is nothing unclean of itself: but to him that esteemeth any thing to be unclean, to him it is unclean.
15 But if thy brother be grieved with thy
meat,
[βρωμα, food] now walkest thou not charitably. Destroy not him with thy
meat,
[βρωμα, food] for whom Christ died.
16 Let not then your good be evil spoken of:
17
For the kingdom of God is not meat and drink;
but righteousness,
and peace, and joy in the Holy Ghost.
18 For he that in these things serveth Christ is acceptable to God, and approved of men.
19 Let us therefore follow after the things which make for peace, and things wherewith one may edify another.
20
For meat [βρωμα, food] destroy not the work of God.
All things indeed are pure;
but it is evil for that man who eateth with offence.
21
It is good neither to eat flesh,
[κρεας, flesh] nor to drink wine,
nor any thing whereby thy brother stumbleth,
or is offended,
or is made weak.
It is good
not to eat animal flesh, (κρεας), and again, quite the negative statement. Paul is using the second great commandment, love your neighbor as yourself, (which surely includes your brother in Meshiah), to argue against eating meat while at the same time he is avoiding condemning anyone.
