Changes in digestive enzyme activity during initial ontogeny of bay snook Petenia splendida
Fish Physiology and Biochemistry, 2011Several samples of P. splendida larvae were obtained from eggs until day 60 after hatching (dah) to determine acid and alkaline proteases, trypsin, chymotrypsin, leucine aminopeptidase, α-amylase, lipase, and acid and alkaline phosphatase activities using biochemical techniques.

Summary The ovarian follicle growth in Petenia splendida and Parachromis managuensis was analyzed. Both species presented analogous follicular growth, reaching similar values within the gonadosomatic and somatic indices (IG) to those reported in other cichlids; however, with regard to maturity, these indices were significantly greater in Pe.

A new, monomorphic trypanosome, Trypanosoma magdalenae sp. n. was found in five of 38 fish, Petenia kraussii, from the Rio Magdalena in Colombia, South America. It is the first trypanosome species designated from freshwater teleosts in Colombia. The trypomastigotes measured in 42.4 micron +/- 2.05 SD (range, 39.8 - 45.6) by 2.1 micron +/- 0.20 (2.0 - 2.

Campechetrema herrerai n. gen, n. sp. is described from the cichlid fish Petenia splendida from EI Vapor lagoon, an oligohaline lagoon, Campeche, México. It is distinguished from other genera of Cryptogoniminae by the presence of a single gonotyl, a preequatorial acetabulum, few vitelline follicles, and lack of pars prostatica and prepharynx.

In this study, we used sequences of mitochondrial and nuclear markers to test the hypothesis that Tabascotrema verai Lamothe-Argumedo and Pineda-López, 1990, a parasite of the cichlid Petenia splendida Günther, 1862 in Middle America, represents a single species, following a molecular prospecting approach. One-hundred and five individuals of T.

The complete mitochondrial DNA of the bay snook, Petenia splendida , a native Mexican cichlid.
Mitochondrial DNA Part A, 2014The mitogenome of the tenguayaca, Petenia splendida (GenBank accession number KJ914664) has a total length of 16,518 bp, and the arrangement consist of 15 protein-coding genes, 2 ribosomal RNA (rRNA) genes and 22 transfer RNA (tRNA) genes. Gene order was equal to the mitogenomes of other new world cichlids.

Summary We report the first description of the ontogenic development of the axial skeleton and unpaired fins of hatchery reared bay snook (Petenia splendida, Perciformes: Cichlidae) from hatching (5.3–5.5 mm in standard length, SL) to the juvenile stage (16.1–17.5 mm SL) by means of alcian blue-alizarin red staining.

Petenia kraussii Steindachner (Pisces: Cichlidae) was collected from Lake Valencia, Venezuela from April 1973 to April 1974. A total of 457 specimens were examined for stomach contents, and 471 were analyzed for length‐weight relationship, sexual condition including fecundity and parasitism. P.
