Dietary phosphorus requirement of pejerrey fingerlings (Odontesthes bonariensis) [PDF]
To determine the available phosphorus requirement of pejerrey fish, four semi-purified diets were formulated to contain increasing available phosphorus levels (0.90, 2.7, 5.7 and 8.3 g/kg).

Diets of Three Sympatric Grebe Species in Lake Titicaca Indicate Possible Dietary Niche Partitioning. [PDF]
Lake Titicaca is home to three grebe species whose diets have not been thoroughly studied. In this natural history note, we provide the first description of the diets of these species and how they overlap and differentiate. ABSTRACT Dietary niche partitioning is a fundamental process in community ecology, of interest to both conservationists and ...

Pleomorphic Adenoma-Like Tumor in the Kidney: Case Report of a Rare Mixed Tumor. [PDF]
Background Pleomorphic adenoma is the most common salivary gland tumor and is notably able to metastasize while displaying a benign‐appearing morphological appearance, greatly resembling that of the primary tumor. Case Report Here, we report a case of a 66‐year‐old male who presented with a 7‐month history of a left upper renal mass.

¿El otolito de pejerrey (Odontesthes bonariensis), refleja el estrés ambiental? [PDF]
It has been proven that otoliths reflect morphology, morphometry and chemical composition of the environment that fish frequent. However, it has not been established if extreme environmental changes can be reflected by such structure.

Modelo de supervivencia para los estadíos poslarvales del pejerrey Odontesthes bonariensis [PDF]
La supervivencia de los peces adultos es representada por el clásico modelo exponencial. Sin embargo, el mismo no estima en forma apropiada la densidad de las etapas de larva y juvenil.

Abstract The evolution of sex chromosomes and their differentiation from autosomes is a major event during genome evolution that happened many times in several lineages. The repeated evolution and lability of sex‐determination mechanisms in fishes makes this a well‐suited system to test for general patterns in evolution.

Abstract Aquaculture is the fastest‐growing food‐production sector and is striving to become a long‐term sustainable approach to meet the rising global demand for seafood. During the expansion and advancement of aquaculture, minimizing ecological impacts should occur concomitantly with maximizing production. Farmed fish, often genetically distinct from

Six experimental diets (crude protein 12.58%, crude fat 1.93%, and total energy 10.72 kJ/kg) containing 0.24%, 0.37%, 0.51%, 0.62%, 0.77%, and 0.89% phosphorus were formulated to evaluate dietary phosphorus requirement for sea cucumber Apostichopus japonicus. The feeding trial was conducted in 18 fiberglass tanks (220 L) for 63 days.
