“…Females tend to direct part of the energy investment into the reproductive process, a process known as 'reproductive drain', which makes it possible to observe differences in allometry when compared to males (Dall et al 1990, Reis-Júnior et al 2019, 2023. The weight-length relationships follow the same pattern: even though the sex differences in allometry for the parameter b is well-known and associated with differentiated reproductive investment (Leite-Jr & Petrere-Jr 2006, Reis-Júnior et al 2023, it is also possible to observe a monthly variation in b for some species (see, e.g., Xiphopenaeus kroyeri in Reis-Júnior et al 2019) and an annual variation, suggesting changes in competition for food resources in these populations (see Rimapenaeus contrictus in Oliveira-Souza & Lavrado 2017). Pauly et al (2022) added a new element to this discussion, stating that limiting oxygen for water breathing organisms, including crustaceans, may be the most limiting factor responsible for some of observed sexual differences (known as the 'gill oxygen limiting theory' or simply GOLT).…”
