Locality Soquel Creek upper 100 m of estuary entirely upstream of MAB77-52
Latitude-Longitude 36.9776667°N, 121.9566889°W Bottom Type cobble, sand, mud, emergent grasses
Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 21 C. No males in reproductive coloration, only 1 adult stickleback seined. All sticklebacks collected, many Cottus thrown back.

Depth Width Salinity 32 Gear 10 ft, 1/8 inch mesh seine
Locality Corcoran Lagoon, mouth of Rodeo Creek
Latitude-Longitude 36.9607°N, 121.983775°W Bottom Type mud
Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 26 C. Males in nuptial coloration were extremely abundant. Gravid females were extremely abundant. Adult stickleback and small fry were extremely abundant. However, intermediate fish were very rare. Green heron seen landing at edge of lagoon. This is a marine estuary. It is choked in the areas seined with aquatic grass. It appears that the sticklebacks were breeding at the edges of the grass because most adult fish were seined in these areas and almost all fish were either nuptially colored males. Males with post-nuptial melanism or large females of which were gravid. Small sticklebacks were very abundant, especially within the grass. Also caught Eucyclogobius newberri.

Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 20.5 C. All fishes were seined along the margin of a 90 m long wide spot in the creek below which the stream was dry for 40-50 m followed by pools and another shorter dry stretch. This wide spot was mostly 10-15 cm deep except along one shore where there were large slabs of concrete and twigs in water. This is where most of the fish were found. The largest and most abundant Cottus occured where the algae from one side approached the twigs on the other at the downstream end. Dragonfly naiads present and as in every station on this creek, crayfish have been abundant. Also caught Catostomus occidentalis, Cottus asper, and Oncorhynchus mykiss.

Locality San Simeon Creek, south fork
Latitude-Longitude 35.6296028°N, 121.0414417°W Bottom Type sand, algae
Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 22 C. All 5 scorable fish were low plated. 4 fish came from pool from which data above is presented, all were low plated fish. 7 fish came from a small puddle just upstream <1 cm deep and about 25 cm in diameter. This puddle was drying. 1 fish from this puddle was countable and it was low morph. A belostomatid was seen with a captured water strider, but I did not see it get captured. Downstream of here is a 3 m falls and access is poor in this area. Thus it is very unlikely that sticklebacks are introduced.

Locality Little Pico Creek
Latitude-Longitude 35.6542472°N, 121.1520472°W Bottom Type mud - thick
Acc. Number 2018-X:19 Specimen Remarks m, f, juveniles. Fixed in 10% buffered (dolomite) formalin ~1 month.
Collecting Event Remarks Water temp. = 18 C. This is a very isolated pool along a cliff face. The stream is almost entirely dry for several hundred meters downstream. The pool is probably always in shade, accounting for the low temp and high density of sticklebacks. Enough sticklebacks were obtained in 1 seine haul for a complete sample. Some large males had poorly developed nuptial coloration.
