The Pacific Sierra, also known as the Mexican Sierra, belongs to the mackerel family (Scombridae) and falls under the Scomberomorini tribe or the Spanish mackerels. This bony, ray-finned fish boasts a fusiform body shape, characterized by an elongated and compressed form. Its coloration ranges from bronze-green to bluish-black on the dorsal area, transitioning to silver-white ventrally. Along its sides, you'll find 3 to 8 rows of small, round orange spots, adding a touch of vibrancy to its appearance.
One distinguishing feature of the Pacific Sierra is the row of gold dots that adorns the area just beneath its lateral line. Its anal fin is white, while the first dorsal fin is black, and the second dorsal fin is yellowish with a black margin. The pectoral fins of the Pacific Sierra are dusky. Additionally, this species possesses a set of strong, sharp, triangular teeth, making it well-equipped for its predatory lifestyle.
Pacific Sierras are known for their aggressive eating habits. They primarily prey on herrings, clupeids, and anchovies. Their voracious appetite ensures they can sustain their growth and thrive in their marine environment.
In terms of size, Pacific Sierras can reach impressive measurements of up to 39 inches and weigh up to 18 pounds. These dimensions make them a substantial catch for anglers seeking both a challenging fishing experience and a rewarding prize.

Premium Pricing: The Pacific Sierra tends to command a higher price compared to other types of mackerels, making it a premium choice for seafood enthusiasts.
Identification Challenges: Although the Pacific Sierra is easily recognizable, it can sometimes be mistaken for the Spanish Mackerel, predominantly found in the Pacific Ocean, or the Gulf Sierra, which features 21 to 27 gill rakers and two rows of yellow spots.

Fishing for the Pacific Sierra requires some specific techniques to enhance your chances of a successful catch. While there are regulations in place to ensure the species' sustainability, recreational anglers can still enjoy the thrill of targeting this magnificent fish.
1. Bag Limits and Seasons
In certain parts of the United States, recreational anglers are allowed to catch a maximum of 10 Pacific Sierras per bag daily. However, it's important to note that their availability is seasonal, and they cannot be caught year-round.
2. Bait and Lures
Both artificial lures and natural baits can be effective when targeting Pacific Sierras. Given their sharp teeth, it is crucial to use a wire leader to prevent them from biting through the fishing line. Shiny lures often attract their attention, while baits such as sardines and anchovies can also be successful.
3. Tackle and Techniques
To increase your chances of success, it's recommended to use appropriate tackle for Pacific Sierra fishing. Light tackle may prove inadequate due to the fish's size and strength. Anglers often find the process of landing Pacific Sierras to be an exhilarating and enjoyable sport.
4. Commercial Fishing
Commercial anglers play a significant role in the capture of Pacific Sierras, with an annual catch of approximately 15,000 tons. However, it's important to note that the population of Pacific Sierras has experienced a slight decline over the years. Gill nets are commonly used in commercial fishing operations to target these valuable fish.
Pacific Sierras are primarily found in the Pacific Ocean, specifically spanning from California to Antofagasta in Chile. As a coastal pelagic species, they form schools in depths of approximately 50 feet. These fish prefer water temperatures below 74 °F. For spawning purposes, they inhabit coastal waters, while juvenile Pacific Sierras can be found close to sandy beaches. Adult specimens tend to reside in deeper waters along continental shelves.
