    (Universidad Técnica de Manabí, 2018) Espinoza Espinoza, Martha Lucia ; Troya García, Juan José ; Panta Vélez, Rodolfo Patricio
    The abundance, growth and mortality of a clam population, Leukoma asperrima (Sowerby, 1835), was determined in the Chone River estuary between July and December 2016. The collection of the clam specimens was carried out in 5 transects perpendicular to the tide line of 100 meters in length collecting all the organisms contained in the sediment with a square of PVC tube of 1.0 m2. Biometric analysis was performed as total length (mm) and total weight (g) to estimate the population structure, growth parameters (L∞, K, t0, Tmax), growth index (Ø '), total length-total weight ratio, total mortality, natural mortality, fishing mortality and exploitation rate of the resource. L. asperrima presented an abundance and average biomass was 3.50±0.61 ind/m2 and 96.54±15.45 g respectively, with an average total length of 38.64±0.56 mm and average total weight of 27.58±0,80 g. The growth parameters were L∞= 54.60 mm; K= 0.41/year; t0= - 0.34 and Tmax= 6.97. The relation total length and total weight was expressed by the equation Pt= 11.874e0.0201 Lt (r2= 0.11). The estimates of the total mortality rate obtained were Z= 1.16±0.17/year, natural mortality 0.43; fishing mortality 0.73 and exploitation rate 0.63. The values of the parameters of growth and mortalities for this species are the first to be estimated in the estuary of the Chone River and are considered to be useful antecedents for the evaluation and management of the resource.

    This research was carried out in the facilities of the Technical University of Manabí, School of Aquaculture and Fisheries during the months of February to November of 2018, with the objective of conditioning chame reproducers Dormitator latifrons (Richardson 1844) with different diets for his gonadal maturation in the laboratory. The reproducers were obtained from different sites in San Isidro, Chone and Tosagua. During the conditioning process part of the organisms were subjected to curative treatments with oxytetracycline, lithofloxin, cypro-plus, piperazine, enrofloxacin and neguvon as they had bacterial lesions. There was greater susceptibility in male organisms with 54.17%, however, survival was excellent with 92%. After overcoming the quarantine, 2 protein treatments (28% and 35% protein) were applied to achieve gonadal maturation of females and males, each with 2 replicas. At the end of the crop there was no increase in body weight in any treatment having a decay of 21.57 g for females fed the diet of 35% and 15.83 g in those who were fed with 28% protein. In the males fed 35% protein there was a loss of 13.43 g and with the diet of 28% the loss was 14.81 g. During a period of 3 months of control of the feeding variables in this study for females and males of D. latifrons maintained on a diet of 35% and 28% did not present an increase in weight and height, with an apparent reabsorption of the gonadal tissue. The recorded data of physical and chemical parameters (temperature, oxygen, pH and ups) were kept within the optimum cultivation ranges for D. latifrons throughout the investigation.

    A technical project was carried out for the conditioning and commissioning of Zamorano tanks for the pre-breeding of aquaculture organisms in the School of Aquaculture and Fisheries, Technical University of Manabí, extension Sucre, in the period from November 2017 to January 2018. Zamorano tanks were created for the purpose of storing the water resource, since a few years ago they have been seen as an alternative to incorporate the development of fish production due to the ease of construction and lower cost that they represent compared to fish ponds geomembrane. Thanks to its circular shape, it helps the constant movement of water inside, which allows to stabilize physical chemical parameters of the water, improving the environmental conditions of the pond, and also facilitates the uniform distribution of the fish. Zamorano tanks are located in an area of 36 m2 , each 3 m in diameter, with a height of 1.20 m and 1 m of water level. The total water storage capacity is 8482 liters, while the total water in production use is 7068.6 liters (7 m3 ). The ponds are designed to culture aquaculture species, especially in the pre-breeding phase, (for example in the cultivation of red tilapia with a planting capacity of 300 organisms per cubic meter). The costs of materials and services used during the implementation and conditioning of the Zamorano tanks for the pre-breeding phase were determined, giving an initial investment value of $ $2.468,35 dollars for the construction, adaptation and start-up of the Zamorano tanks. The implementation and adaptation of artisanal Zamorano tanks will contribute to the acquisition of technical knowledge aimed at students of the School of Aquaculture and Fisheries of the Technical University of Manabí extension Sucre.
