M = Mangrove Jack aka Mangrove Red Snapper (As its name implies, the mangrove red snapper is commonly found in mangrove-lined estuarine systems, although is known to migrate to offshore reefs to spawn. As they mature, mangrove red snappers move into open waters, sometimes hundreds of kilometers from the coast to breed. These larger fish are sometimes caught by bottom-fishers with heavy tackle, though they still remain difficult to land due to their speed and proximity to sharp reef bottoms … Wikipedia). Mangrove Jacks are excellent eating fish and reveal firm, sweet tasting white flesh. Many anglers even rate the taste of jacks higher than barramundi!
