Reproductive Dynamics of the Seabob Shrimp Xiphopenaeus kroyeri in Trawl Fisheries in Southeastern Brazil Amanda Soares dos Santos, Cecília Fernanda Farias Craveiro, Hildemário Castro-Neto, Caroline Vettorazzi Bernabé, Douglas da Cruz Mattos, Leonardo Demier Cardoso, Adriano Teixeira de Oliveira, Paulo Henrique Rocha Aride, Henrique David Lavander, Maria Aparecida da Silva Biology, 2025 Seabob shrimp Xiphopenaeus kroyeri is under heavy capture-pressure in the western Atlantic, requiring periods of fishing suspension to protect the propagation of the species in the wild. This work aims to describe the stages of gonadal development and the ovaries of X. kroyeri in trawling in the southeastern Atlantic Ocean of Brazil associated with climatic characteristics of temperature and precipitation. In total, 3658 specimens were captured in monthly collections from March 2019 to February 2020. The female gonads were classified macroscopically and microscopically according to the maturation stage and correlated with precipitation and temperature data. Five stages of maturation were observed: immature, initial maturation, advanced maturation, mature, and spawned. The highest percentage of mature females was found in May and July, and the average size of the female cephalothorax at the first gonadal maturation was 1.7 cm. The recruitment period was observed in April, with more juveniles. Precipitation showed a negative correlation with the number of mature females. April, May, and July are essential for the life cycle of the X. kroyeri population on the coast of Espírito Santo, Brazil. The results suggest that the current closed season for the species should be reconsidered.
Capture and Maintenance of Balistes capriscus for Aquaculture and Conservation Douglas da Cruz Mattos, Leonardo Demier Cardoso, André Batista de Souza, Marcelo Fanttini Polese, Tiago Queiroz de Morais, Jones Santander-Neto, Paulo Henrique Rocha Aride, Adriano Teixeira de Oliveira, Maria Aparecida da Silva, Henrique David Lavander Fishes, 2025 The gray triggerfish Balistes capriscus has a wide geographical distribution and is used for commercial and recreational fishing worldwide. In this study, we aimed to provide technical knowledge for developing strategies for the sustainable production of gray triggerfish in aquaculture systems by characterizing the capture procedures for broodstock acquisition and developing a protocol for species maintenance in captivity. Broodstock maintenance data were collected over six months (April to September) each year, whereas breeder data were collected over three months each year (November to January). The number of shipments, capture, and survival of B. capriscus was 100%. The animals grew on average by 9.99 ± 0.11 cm over 9 months and increased their average weight by 1.658 ± 0.1 kg, representing a specific growth rate of 0.62% and an average daily weight gain of 6.14 g/day. The species were fed by alternating the supply of fresh food (minced fish, fish fillets, shrimp, squid, minced octopus and crab), divided into two times, 9:00 a.m. and 4:00 p.m., and offered until the animals were satiated. Regarding the structures used to maintain the breeding stock, 15,000 L tanks are recommended to keep up to 30 breeding individuals.
Kidneys and adrenal glands of Caiman yacare (Daudin, 1802) (Crocodylia: Alligatoridae): morphology and morphometry MARIANA O. LIMA, LEONARDO L. GORZA, EDUARDO JOSÉ S. BORGES, YHURI C. NÓBREGA, LEONARDO O. TRIVILIN, RODRIGO G. FIGUEIREDO, MARIA APARECIDA DA SILVA Anais Da Academia Brasileira De Ciencias, 2025 Crocodilians are semi-aquatic reptiles with highly sophisticated anatomy and physiology that are well adapted to dwell in freshwater environments or be exposed to brackish and saltwater, indicating the complex nature of the organization and function of the urinary system in these animals. The objective of this work is to describe the morphology of the kidneys and adrenal glands of <italic>Caiman yacare</italic>, providing morphometric comparisons between male and female animals. It is concluded that macroscopically, the kidneys had an elongated oval shape, reddish-brown color, and greater width in the middle region. The kidneys are associated with the wall of the coelomic cavity, together with the adrenal glands and gonads. Histologically, the renal structure consisted, from the outer periphery to the inner core, of the collecting tubules, the cortical region, the proximal and distal convoluted tubules, the renal corpuscles and the medullary region. The adrenal glands are composed of two types of tissue: adrenocortical tissue and chromaffin tissue. Morphometric analyzes revealed that male kidneys exceeds female kidneys in most macroscopic biometric dimensions. The diameter of the renal corpuscles for both sexes was greater in the caudal portion of the right kidney, and in the middle portion of the left kidney, for males.
Co-feeding period on the survival and growth of larvae (Botia lohachata) during the feeding transition Paulo José Fosse, Douglas da Cruz Mattos, João Carlos Fosse Filho, Leonardo Demier Cardoso, Marcella Costa Radael, Maria Aparecida da Silva, Manuel Vazquez Vidal Junior Ciencia Rural, 2024 This study evaluated the effect of the co-feeding (C) period on the growth and survival of larvae of the yo-yo loach Botia lohachata ornamental species during the weaning period from live food (LF) to inert food (IF). The breeders were subjected to induced spawning using crude pituitary homogenate. A total of 2,400 larvae were used with an average initial weight of 0.39 ± 0.09 mg and an average total length of 4.08 ± 0.21 mm, from a single breeding pair. The live food was newly hatched nauplii of Artemia franciscana, and the inert diet was a commercial ration with 55% crude protein and two particle sizes (142-350 µm and 350-500 µm). As the first food, all larvae received A. franciscana during the first six days, except for the fasting (NC) and inert food (IF) groups. The following co-feeding strategies were employed: C4 = 4 days of co-feeding, C8 = 8 days of co-feeding, C12 = 12 days of co-feeding, and LF = Artemia during the entire experimental period. The longest period with live food promoted better larval growth rates. The specific growth rate of larvae fed live food during the entire period (LF) was higher than that of the other groups, followed by the co-feeding strategies. There was no effect (P > 0.01) on larval survival in the LF, C12, C8, and C4 groups, which ranged from 41% to 53% after 30 days. Treatment R resulted in high mortality and low growth, suggesting that live food should be the first food source for B. lohachata larvae.
Morphological comparison of the larynx and trachea of Chelonia mydas (Linnaeus, 1758), Caiman yacare (Daudin, 1802) and Caiman latirostris (Daudin, 1802) MARIANA O. LIMA, LEONARDO L. GORZA, EDUARDO JOSÉ S. BORGES, VIVIANE T. DE PAULA, LOUISIANE C. NUNES, YHURI C. NÓBREGA, RODRIGO G. FIGUEIREDO, MARIA APARECIDA DA SILVA Anais Da Academia Brasileira De Ciencias, 2024 The larynx is in the lower respiratory tract and has the function of protecting the airways, controlling, and modulating breathing, assisting the circulatory system, and vocalizing. This study aims to describe the anatomy and histology of the skeleton of the larynx and trachea of the species Chelonia mydas, Caiman yacare and Caiman latirostris. The study was conducted at the Federal University of Espírito Santo (UFES), using nine specimens of Ch. mydas, 20 of Ca. yacare and four of Ca. latirostris. Samples of the larynx and trachea were collected, fixed, and sent for dissection of the structures and subsequent macroscopic analysis. For histology, samples were processed by the routine paraffin embedding method and stained with hematoxylin-eosin and Verhoeff. For the three species, two arytenoid cartilages, a cricoid cartilage, a hyoid apparatus composed of a base and two horns were found. In Ch. mydas, two structures called thyroid wings were observed, not found in crocodilians. The trachea of crocodilians presented incomplete tracheal rings and musculature, while the trachea of Ch. mydas presented complete tracheal rings. Histologically, the entire cartilaginous skeleton of the larynx of the three species, as well as the tracheal rings, are constituted by hyaline cartilage.
Anatomopathological changes in laying quails DÉBORA C. NEIVA, MATHEUS J. DOS S. CANDIDO, AMANDA A. ASSIS, THAIS G. TAVARES, MÁRCIO P.A. CORREIA, EMERSON A. DE O. SOUZA, DIRLEI M. DONATELE, IGOR C.K. DA CRUZ, ISABELLA V.F. MARTINS, MARIA A. DA SILVA, JANKERLE N. BOELONI Anais Da Academia Brasileira De Ciencias, 2024 The objective of the current study was to carry out a survey of the main anatomopathological alterations in raising quails and evaluate possible interference of these in the bone tissue. To obtain the data, 23 quails were collected from farm in the central Serrana region of Espírito Santo. Necropsies with macroscopic descriptions, microbiological, coproparasitological, radiographic and histomorphometric tests were carried out. It was done data descriptive analysis and average comparision using Student T test. It was found that they presented lesions predominantly in the digestive system, followed by urinary and reproductive, and muscular system, were the altered color of the liver (47%) was the most frequent lesion. In the parasitological exams, it was found oocysts of Eimeira sp. (39.13%). In the microbiological exams, it was detected predominantly Escherichia coli (83%). Moderate osteopenia in quails, but the percentage of trabecular bone on bones was similar between healthy and diseased quails, without bone changes in histology. Microscopically, it was observed lung congestion as predominant lesion. It is concluded that there was predominance of alterations in the digestive system and mild parasitic infection; and although there was moderate level of osteopenia, there wasn't bone change as a result of the observed infections.
Pathological changes by spirorchiid eggs in hawksbill sea turtle (Eretmochelys imbricata) stranded off brazilian coast MARIA APARECIDA DA SILVA, RAPHAEL M. MEDINA, HASSAN J. LEANDRO, RACHEL B. RIBEIRO, MARIAH B.R.G. PETRONILHA, EULÓGIO CARLOS Q. DE CARVALHO, RENATO LUIZ SILVEIRA, MAX R. WERNECK, EDUARDO SHIMODA Anais Da Academia Brasileira De Ciencias, 2022 Eretmochelys imbricata (hawksbill turtle) is classified as a critically endangered species at world level; in Brazil, it is listed among the threatened species. Spirorchiids are parasites of the circulatory system of chelonians which may cause serious lesions in the various tissues of the host due to deposition of eggs in the bloodstream. In this context, the aim of the present study was to describe the pathology caused by spirorchiid eggs in E. imbricata from the Brazilian over a five year period. A total of 29 animals were analyzed, of which nine (31%) presented lesions associated to spirorchiids eggs. The lesions were: granulomatous enteritis in six (66.66%), granulomatous splenitis in five (55.55%), granulomatous hepatitis in three (33.33%), granulomatous pneumonia in three (33.33%), granulomatous pancreatitis in two (22.22%), and granulomatous adrenalitis in one specimen (11.11%). Concluded the main lesion in Eretmochelys imbricata was giant-cell granulomatous inflammatory reaction to the parasite's eggs. Animals exhibiting poor physical health were more susceptible to presenting such lesions.
Ovarian development of Xiphopenaeus kroyeri (Crustacea: Penaeidae) from Espírito Santo, southeastern Brazil C. V. Bernabé, C. F. F. Craveiro, D. C. Mattos, P. H. R. Aride, A. B. Souza, L. A. Bassul, M. F. Polese, L. D. Cardoso, M. A. Silva, H. D. Lavander Brazilian Journal of Biology, 2022 This study aimed to describe and characterize the stages of gonadal development of females of Xiphopenaeus kroyeri caught by artisanal fishers in Espírito Santo state, southeastern region of Brazil. All females (n= 1,831) were subjected to macroscopic and microscopic morphological analysis (n= 333) of the ovaries. From the morphology, coloration and degree of turgidity of the fresh ovary, macroscopic analysis determined five stages of gonadal development. The macroscopic analysis showed difficulties in differentiating the immature and spawning stages due to the similarity between the colors of the ovaries, which confirms the need to perform the macroscopic and histological analysis simultaneously for fisheries management studies. Microscopic observations allowed us to analyze the following six stages of cell development: oogonia, previtellogenic oocytes, primary vitellogenic oocytes, secondary vitellogenic oocytes, mature oocytes and atretic oocytes. From this, five stages of gonadal development were defined, i.e., immature, early development, advanced development, mature and spawned. The presence of peripheral bodies was not observed in this species. These results help to clarify and better understand the reproductive and population aspects of the Atlantic Seabob, which are fundamental for the establishment of management and conservation measures of this resource.
