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...

The age, growth, and longevity parameters of crocodile shark, Pseudocarcharias kamoharai, from Santa Rosa, Ecuador were estimated. A number of 328 organisms were analyzed, 158 females (69 to 117 cm total length, TL) and 170 males (72.5 to 110 cm TL). The relationship between the vertebra's radius and TL was moderate (r 2 = 0.63), indicating a relat...

Using data from 1991 to 2019, we develop a method to study hyperstable fished stocks relaxing the assumption of constant catchability, hence direct dependence of catch-per-uniteffort and biomass. Information criterion was used to choose the best model including a Cobb-Douglas function for gulf corvina (Cynoscion othonopterus), a sciaenid fish endem...

Catch and fishing effort data are generally available, hence surplus production models are commonly used to conduct assessments. However, hyperstability resulting from spawning aggregations (SA) pose challenges to determine status and inform management of many fisheries resources. Using data from 1991 to 2019, we develop a method to study hyperstab...

The crab fishery of the genus Callinectes is one of the most important fisheries in Mexico. Sonora and Sinaloa are the states on the eastern coast of the Gulf of California, the mainland coast. Sinaloa encompasses the greatest production in Mexico of these species, in particular the Bahía Santa Maria La Reforma (BSMR), supplying the most important...

During the last 50 years, the increase in the efforts of the longline fleet in the Eastern Pacific Ocean (EPO) resulted in an increase in the capture of the swordfish Xiphias gladius. We analyzed a historical database of swordfish catches (1980–2020) reported by the industrial longline fleet to the Inter-American Tuna Tropical Commission (IATTC), w...

Modeling individual growth in marine species for aquaculture encounters many difficulties when the species pauses its growth but resumes its later after the disrupting phenomenon (environmental or physiological) has been overcome. Seasonal or oscillatory growth has been addressed by modifying existing models, such as von Bertalanffy and Gompertz, t...

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...

The totoaba (Totoaba macdonaldi) is a sciaenid (croaker) fish endemic to the Gulf of California with high commercial importance. Because it was considered at risk of extinction (since 2021 it was reclassified as vulnerable by the IUCN), and aquaculture procedures were developed for restocking and commercial purposes. The present study was conducted...

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...

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...

Full-text available
Obtaining the best possible estimates of individual growth parameters is essential in studies of physiology, fisheries management, and conservation of natural resources since growth is a key component of population dynamics. In the present work, we use data of an endangered fish species to demonstrate the importance of selecting the right data erro...

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 pearl oyster Pteria sterna produces pearls from animals gathered from the wild but spat collection is increasingly unreliable. Therefore, hatchery support is required to supply spat for aquaculture operations. In this study is described the hatchery processes to produce spat of P. sterna in a pilot‐commercial grade. Growth and survival (relativ...

Production of Crassostrea gigas in hatcheries may be affected by different factors influencing spat quality; this will be reflected during its cultivation in the field. The main indicator of quality is growth. Growth modeling is a form of determining individual growth patterns in bivalves. In this study, multi-model inference (MMI) and the Akaike i...

Management of commercial fisheries resources is commonly done assuming that populations are spatially homogeneous throughout their geographic range. However, uneven gene flow can result in gradients of genetic diversity that can affect population dynamics and management reference points and may contribute to overfishing. We examined whether the bro...

This work analyses how the fecundity of the brown swimming crab, Callinectes bellicosus, varies along the coast of Sonora in the Gulf of California. Ripe female crabs were collected during May 2015 in four zones, and fecundity was determined and compared with carapace width (CW), total body weight (TW) and egg mass weight (MW). TW ranged between 10...

Growth estimates of animals are often based on a single data set. The sizes used to determine these estimates can nevertheless be biased by the selectivity of the data source and how well the data represent a population. The average growth of the brachyuran crab Ucides occidentalis (Ortmann, 1897) (Ocypodidae) had been previously estimated utilizin...

We examined the length-weight relationship (LWR) in Callinectes bellicosus (Stimpson, 1859) (Brachyura: Portunidae). The power model W = aLb is practically the only model used for allometry in aquatic animals, where the allometric coefficient b is considered as constant and determined by the overall size of the animal. We tested the hypothesis that...

The objective of this research is to assess the main social and economic effects on local fishermen in El Golfo de Santa Clara, as a result of the severe fishing restrictions enforced to protect the marine mammal "vaquita" (Phocoena sinus). Sustainable development includes natural resources conservation and the improvement of the social and economi...

In Mexico, swimming crabs are considered a strategic resource because it supports artisanal fishing when the main fish resource (shrimp) is in closed season. In "Marismas Nacionales" the blue crab fishery is relatively new, and the catches have been maintained due to the national demand and the availability of the resource. Individual growth, sexua...
