As a contribution to the biological knowledge about the sea fan Gorgonia ventalina and the use of this information as a tool to generate conservation and management strategies for this threatened species, a study about its annual growth rate, in different reef areas in Santa Marta and the National Natural Park Tayrona in the Colombian Caribbean took place. Manual measurements of 35 colonies were analyzed and images of 11 colonies were recorded in the beginning and in the end of the field stage. The annual growth rate varies among colonies and areas where measurements were taken. The average annual growth rate obtained with both of the methods was high and oscillated between 7.6 and 8.1 cm/year in height and between 6.9 and 8.3 cm/year wide. The total area...

Crecimiento y mortalidad de la castañeta Cheilodactylus bergien la zona común de pesca Argentino-Uruguaya

Botero, J.; Ospina, J.F..

An experimental culture trial of wild juveniles of jewfish Epinephelus itajara was conducted in two different places in the north coast of Colombia in order to evaluate the growth rate of the species and its tolerance to captivity conditions. Two different groups of fish were evaluated in each place, one fed on an artificial diet and the other on trash fish. All fish were held in floating cages for periods ranging from 63 to 89 days. Results showed excellent individual daily weight increase (6,83 and 12,4 g/day) and specific growth rate (1,4 y 0,96 %/day) for fish fed on trash fish in both places but conversion ratio was too high and inadequate (9,01 and 9,97). Trials with the artificial diet gave negative results because the fish didn’t accept the pellets...

Croissance de juvéniles de Nereis diversicolor nourris avec des détritus d'halophytes

Lucas, Albert.

The japanese palourde Venerupis semidecussata was reared in the Bay of Brest, using hatchery reared spat. Experiments were performed with individuals of lenght 2 to 10 mm raised in a nursery, using raceways with slow running water enriched with unicellular algae, And also with individuals of lenght 8 to 20 mm raised at sea in suspended culture. It was observed that growth depends upon four groups of factors : (1) the functioning and equipment of the raceways, (2) the quantity and quality of the food, (3) the temperature and (4) various physico-chemical factors. When the equipment is satisfactory and when the physico-chemical factors are normal for the species in question, the rate of growth depends essentially on the quantity of food, provided that the...

Croissance de la coque (Cerastoderma edule) en baie de Somme : Morphométrie et Marquage

Meziane, T; Retiere, C.

The comparative effect of the uptake of fresh and degraded detritus of halophytic plants, harvested from salt marches of the Mont Saint-Michel Bay (France), on the growth of a juvenile population of the annelid polychaete N. diversicolor (L.) was studied under experimental conditions in summer 1993. Fresh and degraded detritus of Spartina anglica, Halimione portulacoides and Salicornia europeae, as well as the green algae Enteromorpha sp. were distributed separately to homogenous set of juveniles for a 75 d period. The highest growth rate was obtained for worms fed with Enteromorpha sp. Administration of fresh detritus of a given halophyte species to N. diversicolor juveniles always leads to a significantly higher growth rate than did degraded detritus....

The bay of Somme is the first French field of cockles (Cerastoderma edule) with a production amounting to 3000 tons per year on average. In order to improve the stock management, it is necessary to increase our knowledge of this species. This study is looking at the growth of the common cockle. First, was carried out a morphometric analysis of the two left and right valves, which has revealed a perfect symmetry of the shell and has allowed us to establish strong correlations among the morphometric parameters. Then, a chemical marking study has been realized with calcein and manganese in order to obtain the exact growth. Calcein marking has showed a fluorescent stria only for an half hour immersion time at 150 mg.L-1. Likewise, the manganese marking has...
