The growth of the Pacific white shrimp, Penaeus vannamei was analysed with data from nine earthen ponds in three aquaculture farms located at the mouth of the Gulf of California in the state of Sinaloa, Mexico. Each farm has a different source of water supply: marine, estuarine-freshwater, and estuarine-hypersaline. Growth was estimated with a mult...

In Mexico, the spiny lobster fishery is well established but this is not the case with the slipper lobster fishery. For a sustainable fishery, many biological traits must be known, one of which is growth. The objective of the present study was to probe the multi-model approach to identify the curve that best describes the growth of Evibacus princep...

In Mexico, shrimp catch is the main fishing activity, and the second important species is the blue shrimp, Penaeus stylirostris. Specimens of P. stylirostris collected in 2016-2018 from inland waters (bay) and offshore (littoral) in the Santa María la Reforma lagoon (SMLR) system were analysed. The sexes were separated, and then individuals were me...

Background: Currently, there is no fishery regulation for Hexaplex (Muricanthus) nigritus in northwestern Mexico. The size composition of gastropod H. nigritus was recorded from five islands of Navachiste Bay, Sinaloa (Gulf of California, Mexico). Methods: Samples were taken every two months from February to December 2018. Islands established a geo...

The accompanying microcrustaceans of penaeid postlarvae were analyzed between the mouth of the Presidio River and marine area (southern Sinaloa, Mexico). The samplings were at high tides (May to October 2017). A plankton net at a depth of 1 m. The trawls were every 2 h for 24 h. The water temperatura (25 to 34 ◦C) and salinity (32 to 35 ups). The t...

A stock reduction analysis (SRA) of bigeye croaker Micropogonias megalops was performed based on commercial catch data. SRA solutions were restricted to a 2011 bigeye croaker stock biomass estimate of 14,412 t. The viable solution indicated a reduction in stock of 73.6% from 1983 to 2020 with an initial biomass of 22,186 t. In addition, a possible...

The relative growth of Calappa convexa can be used to identify dimorphism or morphological change related to sexual maturation. The carapace width (CW) against width and length of the propodus of the right and left cheliped were tested to obtain a coefficient of allometry. CW against total wet weight WT values were analysed for length-weight relati...

Length-frequency data of juveniles and sub-adults of Penaeus californiensis were analyzed, collected from January 2002 to January 2003 in the Agiabampo lagoon system and adjacent marine coastal zone. Six models were parameterized with four criteria, in addition to a mixed criterion (fat-tail and depensatory), to estimate the parameters that best fi...

The yellowlegs shrimp Penaeus californiensis is an oceanic species that approaches the coastal zone for its reproduction. However, in the southern Gulf of California, this species also enters coastal lagoons to grow and reproduce. To test the hypothesis that the growth of P. californiensis differs between these two environments, monthly samplings o...

The present study was done under the hypothesis that size variation among individuals of one particular age affects the precise assessment of anticipated growth curve trajectories and their parameters for the marine shrimp, Penaeus vannamei (Boone, 1931). The data come from shrimp farmed in earthen ponds of an aquaculture farm located in the Gulf o...

In the present study we explored the effect of the tidal hour on the postlarvae abundance of the penaeid white-leg shrimp (Litopenaeus vannamei (Boone, 1931)) in three Mexican Pacific coastal lagoons. Correlation analysis of tidal hour against the hourly variation of the abundance of postlarvae was conducted in three regions of the Mexican Pacific;...

The species composition and variation in density (postlarvae m(-3)) of penaeid shrimp postlarvae were surveyed every 14 days in two zones of the Mexican Pacific coast; in the north (Mazatlan, 23 degrees N 106 degrees W) and south (Gulf of Tehuantepec, 15 degrees N 95 degrees W). Sampling coincided with full moon and new moon, and they were carried...
