“…In the present study, the coloration for P. schmitti in the immature and spawned stages was translucent and these were the most difficult stages to be differentiated, especially in females of intermediate sizes, due to the similarity in characteristics and for presenting the same coloration. The same difficulty was reported for P. schmitti in Pernambuco [8], in São Paulo [12], and for other species of penaeids shrimps [12,[18][19][20]22,23].…”

“…The emergence of peripheral bodies (PB) is the main factor that indicates that the ovary is in complete development, and characterizes its mature stage. Gonçalves et al [12] and Craveiro et al [9] demonstrated clear differentiation of cell structure by the presence of PB in the mature ovary of P. schmitti, which was corroborated in the study of gonadal development of other penaeid shrimps [20][21][22][23]. Peripheral bodies were observed in spherical to oval shapes, but can also be found in the form of rods for P. schmitti [8,11].…”

This study describes the reproductive cell development and ovarian developmental stages, and identifies the nongerminal components of white shrimp (Penaeus schmitti) caught off the southern coast of Espírito Santo, Brazil. P. schmitti specimens were collected monthly from March 2019 to February 2020, by artisanal fishing. All shrimps were analyzed macroscopically (n = 181) and females were randomly selected monthly (n = 154) for ovarian histological analysis. The ovaries were extracted for visual analysis and then submitted to histological analysis. Macroscopic analysis determined five stages of gonadal development from the color and turgidity of the fresh ovary. Histological observations allowed us to observe five stages of gonadal development: immature, initial development, advanced development, mature and spawning. This information are fundamental for understanding the reproductive aspects of P. schmitti, as well as other penaeid shrimps, in order to promote preservation of natural stocks and provide information to assist in the development of the reproductive potential of native species in captivity.

“…The main bioecological difference between species, discriminated by hypothetical-deductive knowledge, is related to migration. White shrimp (P. schmitti) and pink shrimp (P. subtilis) need the estuary to complete the life cycle [38,39,75,76], while the seabob shrimp (X. kroyeri) completes its life cycle exclusively at sea [33,40,77]. Another difference between species is the age at rst maturation.…”

BackgroundLocal ecological knowledge (LEK) in fishing communities is generated through interactions between fishers and the exploited resources. It is transmitted through social networks, interdisciplinary structures that drives the dynamics of socio-ecological systems (SES). LEK variability is supposed to depend on the quality and quantity of ecological information flow among different stakeholders. To assess what is driving LEK themes, we hypothesized that the formation of LEK clusters among fishers is determined by network articulation, fisher experience and the commercial value of the exploited species. MethodsThe study area comprises three fishing communities in the Western South Atlantic, in the tropical coastal zone of Brazil where artisanal shrimp fisheries (on Penaeus schmitti, P. subtilis and Xiphopenaeus kroyeri) are a major activity. Data collection took place between March, April, and November 2019. To test our hypothesis, linear regression and bipartite network analyses were performed to visualize the interactions between fishermen groups and LEK themes. The connectivity, nesting, modularity, and centrality parameters in this social network were calculated to test the hypothesis. ResultsOur results indicate that experienced fishers enhance LEK in their networks on the themes of food, mortality, and growth. Furthermore, there are subgroups of fishers with dissimilar knowledge about the exploited shrimp species, one old on the fishery with wide knowledge, other less experienced, just knowing about reproduction and migration themes. ConclusionWe conclude that there is a spatial similarity in the connectivity of fisher’s LEK, mainly concerning the reproductive and migratory dynamics of the target species, but also differences permeated by fishers’ experience and local interests. Managers initiating co-management agreements using reproduction and migration referential variables as benchmarks will be more successful if they incorporate LEK into decision-making. Regional knowledge similarities favor the implementation of management policies at a regional scale potentially reducing conflicts within fishing communities and increasing resource use efficiency.

“…Previous studies in the region have shown that most of the catch (bycatch and target) of the shrimp fishery in Pernambuco occurs in the same area and share the same reproduction season, i.e. between October and March (Lopes et al, 2014(Lopes et al, , 2017Silva et al, 2015aSilva et al, ,b, 2016. Hence, the establishment of Marine Protect Areas (MPA) or a fishery-closing period should improve the conservation of the species and marine habitats exploited by this fishery in Pernambuco.…”

Roughneck Grunt (Haemulopsis corvinaeformis Steindachner, 1868) is the second most important species caught as bycatch of the shrimp fishery in Pernambuco, Northeastern Brazil. However, the population dynamic of this species is poorly known in the region. The aim of this study was to describe aspects of the population structure and reproductive biology of the H. corvinaeformis, providing important information for the development of sustainable management practices. Specimens were collected monthly from August 2011 to July 2012 and quarterly from October 2012 to June 2014. A total of 1,140 individuals was collected; 340 males (29.8%), 391 females (34.3%), and 409 were immature and could not be sexed (35.9%). Total length ranged from 7 to 25 cm. In general, total length of females [12.85 ± 2.49 cm (mean± SD)] and males [12.72 ± 2.46 cm (mean ± SD)] were similar (p > 0.05). The proportion of males and females was similar along the year, except in March. The relationship between total length and total weight was statistically significant (p< 0.05), showing an isometric growth. The (GSI) coupled with the distribution of maturational stages suggests that females reproduce all year around, with a peak during October-November. The length at first maturity (L50) was estimated at 11.88 cm for females and 11 cm for males.
