Individual growth of white shrimp Litopenaeus vannamei (Boone, 1931) and blue shrimp L. stylirostris (Stimpson, 1874) (Crustacea: Penaeidae) by multi-model approach

Abstract

Individual growth of two shrimp species of the family Penaeidae, the white shrimp Litopenaeus vannamei and blue shrimp L. stylirostris were analyzed. The hypothesis was that both species would have an asymptotic growth type with sigmoid shape. The data comes from shrimp farming in earthen ponds of an aquaculture farm located in the Gulf of California, density was 25 post-larvae m-2 in ponds of 1.8 ha. Three asymptotic models were applied to averaged length at age data: von Bertalanffy, Gompertz, and logistic. The model’s parameters were computed by maximum likelihood criterion. Best model was selected according to the Akaike information criterion. The final total length of white shrimp was 128.8 mm and the estimated asymptotic length was 130 mm, after 140 rearing days. The blue shrimp final size was 142.2 mm, and the asymptotic length was 174 mm, after 158 rearing days. For both species, the model which better described the growth was the Gompertz model; consequently the conclusion was that the growth of both species must be sigmoid shape.

Rock Crabs Grapsus Grapsus and Box Calappa Convexa (Crustacea: Brachyura): Potential Fishery Resources

“…With the exception of the studies recently carried out by the group of researchers from the Laboratory of Invertebrates and Benthic Ecology of the Faculty of Marine Sciences of the Autonomous University of Sinaloa (LIEB-FACIMAR-UAS), who have contributed with various studies focosed on knowledge biology of these crab species. This situation is very different from that observed in this area in other commercial decapods crustaceans, in which various fishing biological aspects have been analysed, such as spiny lobster Panulirus [13,14], shrimp penaeid [6,15,16] and crabs Callinectes [17,18]. At present, in these areas fishermen have increased the capture and use of both species of crabs for self-consumption, which has coincided with the Food and Agriculture Organization of the United Nations (FAO), has indicated that these crabs can be used for family sustenance purposes.…”

Effect of different substrates on growth and biochemical composition of the ornamental “red cherry” caridean shrimp, Neocaridina davidi (Atyidae)

“…davidi were compared among different substrates using sigmoid growth functions. These models have become popular in recent decades and have been successfully applied to other crustacean species (Aragón‐Noriega, 2017), ophiuroidea (Stratanenko & Denisenko, 2020), fish (Hart & Chute, 2009; Kielbassa et al, 2010; Wang & Ma, 2016), birds (Brunner et al, 2021; Svagelj et al, 2019), mammals (Thorley & Clutton‐Brock, 2019) and even in plants (Ukalska & Jastrzębowski, 2019). Here, it was found that N .…”

Individual growth analysis of the Pacific yellowlegs shrimp Penaeus californiensis via multi-criteria approach

“…Recent studies have used the multimodel selection approach in penaeid species. Aragón-Noriega (2016) studied the growth in cultivated Penaeus vannamei and P. stylirostris. He concluded that these two species' growth is sigmoid (the best-fitted model he found was Gompertz).…”

“…The previous models are characterized by having an asymptotic parameter. They can be of two forms; sigmoid or negative exponential (Aragón-Noriega, 2016). The sigmoid shape curve, Gompertz, Logistic, Richards, and Johnson type models are characterized by having an inflection point.…”
