Banks of the Pasig River, particularly one I have tried in Barangay Valenzuela, Makati City. Yes, in Makati. People used to catch Knife fish using live bait (guppies, feeder carp, etc). Bait and wait method is best as casting lures will get you a lot of snags. Sizes range from under a kilo to as much as three kilos for a single fish. You can catch bait fish and tiny shrimp from the bank by using a landing net to scoop them up. I have also seen people catch an occasional Snake head and Big head carp. Head over to the Centennial Park in Navotas (located along Manila Bay) and look for a boatman who can take you fishing for Threadfin salmon. Yes, you heard that right. They are in season during the “ber” months, but can be caught year round, depending on how lucky you are. These fish give one hell of a fight if and when you can locate them. Boatmen will usually go around, hunting for schools of Threadfin salmon, and when you find them, toss a casting jig/spoon their way and prepare for a fight. When in season, catches of 2 kilos and up per fish are not uncommon. There are a lot of answers here and while some deal from a general ethics and cultural standpoint and make a lot of sense. However, from a Buddhist point of view, the analysis of karma is far more nuanced and not necessarily intuitive to many. The basis of the action of killing must be another living sentient being. And it must be a living being who is not yourself. From the Buddhist point of view, killing any sentient being even the smallest insect, is an act of killing. In order to have a complete karma, the doer of the action must be alive and acting intentionally from the beginning of making preparations for the action right up through the culmination of the action. In this case the fish is certainly a living sentient being, you are alive and acting intentionally, hence the the first requirement for this to be a karma of killing is complete. Now let’s look at the other aspects.
Of course, the first and third of these perceptions are correct and the other two are mistaken discriminations. In order to have the complete karma of killing, the perception of the object you are killing must be unmistaken in this sense. In this case, you should be aware the the fish you catch are indeed living creatures. The third aspect of thought we need to analyze is which affliction underlies the action. Anyone of the three poisons-desire, hostility, or ignorance can be the underlying cause of killing. Other afflictions may arise at the time of the action, but one of these three will always be present. In other methods of analyzing karma the motivation and the obscuring affliction are combined into a single category. Here, they both fall under the general category of thought; the obscuring affliction refers to one of the three poisons while the motivation refers to the intention that directly motivates the action. While the mental desire here could be born from hunger, the fact that you need fish to satisfy it arises either from ignorance or from attachment/desire for the fish meat. In terms of the agent who performs the action, it does not matter whether you do it yourself or you cause someone else to does it – both of these constitute complete karma. In other words, even if you do not do the killing yourself, if you have the motivation to kill and you cause somebody else to do the killing, that constitutes a complete karma of killing. As for the nature of the action, it does not matter how the killing was carried out. Whether it was done by using a weapon, with poison, by some kind of mantra or black magic-whatever means were involved, the karma will be complete. The culmination of the action is accomplished when the victim dies because of the action of killing-it may be immediately or at a later time.
