English	–	Lizardfish, Spotted lizardfish
Spanish	–	Garrobo, Huavina, Lagarto camotillo, Lagarto garrobo

Assessment Information [top]

Red List Category & Criteria:	Least Concern ver 3.1
Year Published:	2010
Assessor/s:	Lea, B., McCosker, J.
Reviewer/s:	Carpenter, K., Polidoro, B., Livingstone, S. (Global Marine Species Assessment Team)
Justification: This species is widespread in the Eastern Pacific region and is abundant at least part of its range. There is no current indication of population decline from capture as by-catch by shrimp fisheries. It is listed as Least Concern.

Geographic Range [top]

Countries:	Native: Chile; Colombia; Costa Rica; Ecuador; El Salvador; Guatemala; Honduras; Mexico; Nicaragua; Panama; Peru
FAO Marine Fishing Areas:	Native: Pacific – eastern central; Pacific – southeast

Population [top]

Population:	In research cruises conducted by the R/V El Puma between 1990-92 in the Sinaloa-Nayarit area (five cruises) and in the Gulf of Tehuantepec (three cruises), Synodus species were frequently caught in the Sinaloa-Nayarit area and tended to be more abundant further from the coast. In the Gulf of Tehuantepec, the largest catches were obtained off Salina Cruz. The length of this species ranged from six to 29 cm, and they were collected below 30 m. In Sinaloa-Nayarit, this species was more abundant at depths greater than 90 m, and its length range increased with depth. At depths greater than 90 m, only fish over 30 cm were found (Morales-Nin 1996). Differences in abundance between Sinaloa-Nayarit and the Gulf of Tehuantepec may be due to different ecobiological causes.
Population Trend:	Unknown

Unknown

Habitat and Ecology [top]

Habitat and Ecology:	This species is found on soft substrate (Bussing and Lavenberg 1995).
Systems:	Marine

Threats [top]

Major Threat(s):	This species occurs in shrimp trawl by-catch. The larger body lengths for this species found at increased depths in Sinaloa-Nayarit compared to the Gulf of Tehuantepec may be indicative of more exploitative fisheries in the Sinaloa-Nayarit area (Morales-Nin 1996).
