Evaluación del cultivo intensivo del bagre blanco Sorubim lima, Bloch 1801 en estanques de cemento

core
Tissue and Cell, 1999 The ultrastructure of Sorubim lima spermatogenesis during the premeiotic and meiotic periods was studied. Our observations showed that the germ cells in the cysts are connected by cytoplasmic bridges and the mitotic and meiotic divisions are slightly asynchronous.

de Chambrier & Vaucher (1999) compared the proteocephalidean cestode Spatulifer maringaensis Pavanelli & Rego, 1989 from Hemisorubim platyrhynchos (Valenciennes) with similar specimens, which they described as S. cf. maringaensis, parasitising Sorubim lima (Bloch & Schneider) collected in the Paraná and Paraguay Rivers.

On the ampullary organs of the South-American paddle-fish Sorubim lima (Siluroidea, Pimelodidae)
Cell and Tissue Research, 1978Ampullary organs were found in the epidermis of the paddle-fish Sorubim lima; they are distributed all over the skin surface of the fish but are particularly densely grouped in the head region and on the dorsal surface of the paddle. Histological and electron microscopical observations show that their structure is similar to the type of cutaneous ...

Chromosomal Organization of Repetitive DNA in <b><i>Sorubim lima </i></b>(Teleostei; Pimelodidae)
Cytogenetic and Genome Research, 2013Interspaced repetitive DNA elements and segmental duplications have been extensively analyzed in fishes through physical chromosome mapping methods, providing a better comprehension of the structure and organization of the genome of this group. In order to contribute to this scenario, a sequence integration study of different classes of repetitive DNA ...

Fisheries Management and Ecology, 2001
This study examines the diet of Sorubim lima (Schneider) during its early life stages and compares it with available food resources. Prey species preference was estimated by computing the Strauss index. The diet was diverse, and rotifers and cladocerans were the most important items. Pre‐flexion larvae ate rotifers and cladocerans.

Ultrastructure of Sorubim lima (Teleostei, Siluriformes, Pimelodidae) spermiogenesis.
Journal of submicroscopic cytology and pathology, 2001The spermiogenesis and the spermatozoon ultrastructure of Sorubim lima were studied. Our observations showed that early spermatids are round-shaped cells, have spherical nucleus with diffuse chromatin, small quantity of mitochondria and large amount of vesicles in the cytoplasm. During the differentiation process in the nucleus, chromatin compacts in a
