| Se presentan los resultados del estudio biológico de cinco especies de peces ornamentales, a los que se les concede un alto valor para su exhibición en los acuarios. Las especies se caracterizaron morfométricamente con mediciones lineales y del peso, relaciones proporcionales y la relación largo-peso; y se estudió la reproducción y la alimentación. La especie Gramma loreto se caracterizó morfométricamente; los individuos maduros resultaron más altos proporcionalmente; predominaron las hembras en la proporción sexual total; la madurez sexual se presentó en la clase de talla de 35-40 mm en las hembras y de 55-60 mm de LH en los machos; en marzo-abril se puede estimar su período reproductivo; los crustáceos, y dentro de ellos los copépodos harpacticoides... |

| La clasificación adoptada es la del Dr. Leo S. Berg, según la última edici6n (1955) de su "Clasificaci6n de Peces Recientes y Fósiles". Prefiero adaptarme a ella casi enteramente, entre otras razones, para conservar una unidad de referencia. Las otras obras que han servido de base son: "Fishes of North and Middle America", Jordan & Evermann, 1896-1900, abreviado en el texto JEC "Check List of Fishes and Fish like Vertebrates of North and Middle America", Jordan, Evermann & Clark, 1928, abreviado JEC; y los dos vo lumenes publicados de "Fishes of the Western North Atlantic", Partes I y 11, Bigelow & Schroeder, 1948 y 1953, abreviado BS. En conjunto encierran todos log nombres empleados para desig- nar a los peces de nuestras aguas, así como... |

| Obra publicada en 1787. La presente edición facsimilar, de interés para bibliófilos, historiadores público en general, es un reconocimiento a la primera obra científica cubana y a su autor, el portugués Antonio Parra. Para ello fue necesario restaurar la tipografía de la misma debido al mal estado y antigüedad de los ejemplares existentes, no así las láminas, que perderían los detalles originales. Como ninguno de estos ejemplares poseía la cubierta primigenia, la diseñada para su presentación ha tenido en cuenta el estilo de la época. También resultó conveniente, a fin de facilitar esta edición, colocar las láminas al final del texto y reducir al tamaño del formato las láminas A y B que en los originales estaban en forma de hojas plegables. Como la obra... |

| Este trabajo refleja el resultado de las investigaciones realizadas en la inducción al desove de Eugerres plumieri en el periodo comprendido de junio a noviembre de 1976. Se determinó el rango de dosis efectiva de utilizando la hormona Gonadrotopina Coroniónica Humana (HGC), para obtener experimentalmente el desove, fertilización y desarrollo embrionario. Se efectuaron 4 ciclos experimentales donde fueron tratadas 35 hembras, de las cuales podemos considerar como representativas del experimento a 19 de las mismas. De ellas, 3 respondieron completamente al tratamiento hormonal. Las dosis efectivas para inducir al desove y obtener huevos fértiles y larvas son de 3,2 a 3,1 U.I. por g de peso de cuerpo del pez. No se encontraron diferencias entre los índices... |

| Aquatic macrophytes are important components of aquatic ecosystems, but these plants have become a problem due to their occurrence in different regions. Some studies aimed to demonstrate the effectiveness of herbicides to control these macrophytes; however, few studies report the possible ecotoxicological effects. The objective of this study was to estimate the acute toxicity (LC (I)50;96h) and assess water quality variables for glyphosate in the Rodeo® formulation, Aterbane® BR surfactant and mixtures of glyphosate + 0.5% and 1.0% of surfactant, for the guaru fish (Phallocerus caudimaculatus). The guaru was exposed to increasing concentrations of glyphosate and a mixture of glyphosate + 0.5 and 1.0% of surfactant. The mixture of glyphosate... |

| This work evaluated the efficiency of clove oil as anaesthetic in handling and transportation of Nile tilapia, Oreochromis niloticus (Linnaeus, 1758). In the first experiment, safety concentrations of clove oil were assessed by measuring induction times to anaesthesia. The second experiment evaluated exposure times to anaesthetic. Clove oil efficiency during transportation was evaluated in a 24 h experiment using three concentrations of the anaesthetic (0, 9, and 18 mg.L-1). The most appropriate clove oil concentration to induce surgical anaesthesia was 90 mg.L-1. To biometry or other brief handling, the recommended concentration is 50-60 mg.L-1 as it provides fast recovery. Maximum anaesthesia time should be 10 min. The mortality rate of fish transported... |

| Abstract: The use and validation of fish health monitoring tools have become increasingly evident due to aquaculture expansion. This study investigated the hematology and blood morphometrics of Piaractus mesopotamicus, Brycon orbignyanus, Oreochromis niloticus and Rhamdia quelen. The fish were kept for 30 days in 300-liter aquariums, after which they were anesthetized with benzocaine and blood was collected from caudal vessels. In comparison to other species, B. orbignyanus presented the highest hematocrit (Ht), RBC averages and Mean Corpuscular Volume (MCV) with a particular range of data. B. orbignyanus presented lower Ht, Hb, RBC averages and values, and Mean Corpuscular Hemoglobin Concentration (MCHC). Oreochromis niloticus presented lower Ht, Hb, RBC... |

| Tropical fishes like Leporinus macrocephalus Garavello & Britski, 1988 ("piauçu") and the hybrid "tambacu" (Piaractus mesopotamicus Holmberg, 1887 "pacu" male x Colossoma macropomum Cuvier, 1818 "tambaqui" female) were experimentally infected with four inocula of trophonts of Ichthyophthirius multifiliis Fouquet, 1876 (Protozoa, Ciliophora) and the infection level was evaluated. Each one of twelve experimental units consisted of a tank with 200 liters of water and two specimens of each kind of fish. The following treatments were designed to each tank, in triplicate: 8, 16,32 and 64 trophonts. After 8 days of exposure the fishes were killed and the number of trophonts was counted at a stereoscopic microscope. This assay showed to be feasible at... |

| A growth experiment was conducted to determine the optimal dietary protein requirement for juvenile cachama, Piaractus brachypomus. Six semi-purified isoenergetic experimental diets using casein and gelatin as protein sources were formulated to contain graded levels of protein (16, 20, 24, 28, 32 and 36%). Fish initially averaging 15.52±0.33g (mean±SD) were randomly distributed into the tanks (500L) as groups of 20 fish and fed to apparent satiation twice daily for 60 days. The results showed that feed consumption, feed conversion ratio, fish weight gain, specific growth rate, protein efficiency ratio and protein productive value were affected by dietary protein level (P<0.05) . No significant differences were observed in proximal composition of carcass... |

| Centropomidae and Serranidae, sometimes collectively misnamed "sea basses", are suitable for aquaculture in pens, ponds, and raceways around the tropical and subtropical latitudes of the world. Western Atlantic Ocean species were recently considered for farming. South Florida, Mexico, Central and South America and the Antilles areas of the Caribbean Basin have extensive areas suitable for farming groupers and snook. Principal species of interest are the common snook (Centropomus undecimalis ), the fat snook (C. parallelus ), the Nassau grouper (Epinephelus striatus ), Black seabass (Centropristis striatus ), Gag (Mycteroperca microlepis ), and jewfish (E. itajara ). |
