Human trophic level varies. If the individual in question ate only moray eels (who are independently about a trophic level of 4, on account of being mostly piscivorous) then I imagine the human would be at a similar level. If the eel made up a part of an otherwise omnivorous diet, then I expect the person's trophic level to be closer to 2.5-3.0
Third trophic level. It eats insects.
The trophic level is where an organism falls on the food chain. Most birds fall on the highest level, trophic level 4.
When an organism from a higher trophic level eats one from a lower trophic level, it gains energy and nutrients from the consumed organism. This contributes to the transfer of energy through the food chain and helps regulate population sizes in the ecosystem.
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
Owls are at the highest trophic level, the tertiary. The tertiary consumer is a carnivore that eats other carnivores.

The giant panda is a herbivore and primarily eats bamboo, placing it at the primary consumer trophic level.
Humans?
Humans and Bacteria are considered 4th Level consumers.

Other moray eels are the most common predators of moray eels. Barracudas, groupers and people also eat moray eels.
