Length-weight relationships of demersal fishes from the upper continental slope off Colombia

Parameters of the length–weight relationship of the form W=aLb are presented for 45 demersal fish species caught on the upper continental slope of the Caribbean Sea off Colombia. The b values varied between 2.13 and 4.97, with the mean b = 3.042 (95% CI, 2.887- 3.196).

Length-weight relationships of demersal fishes from the Gulf of Salamanca, Colombia: [part 2]

The parameters a and b of the length-weight relationship of the form W=aL super(b) are presented for 37 fish species, belonging to 17 families, caught during a demersal trawl survey over the period December 1995 to March 1998 in the Gulf of Salamanca, Colombia

Length-weight relationships of demersal fishes from the Gulf of Salamanca, Colombia

The parameters a and b of the length-weight relationship of the form W=a L super(b) were computed for 46 species caught in a series of demersal trawl hauls over the period 1995-1997 in the Gulf of Salamanca, Colombia.

Sistemas de contabilidad de gestión y desempeño de joint ventures internacionales: rol positivo de la experiencia de los directivos

[ES] Este trabajo explora el rol de los sistemas de la contabilidad de gestión en el desempeño de Joint Ventures (JV) del tipo 50/50 en la industria autopartista. Se investiga el impacto que la experiencia previa de los directivos tiene sobre la intensidad y propósito de uso de los sistemas de la contabilidad de gestión y como ellos afectan el desempeño de JVs. El estudio de este fenómeno surge a partir de los resultados reportados en tres estudios de campo exploratorios en JVs (Groot y Merchant 2000) y de otros tres casos de JVs internacionales en la industria autopartista (Porporato 2013) en donde se sugieren que el efecto de los sistemas de control de gestión en el desempeño organizacional es secundario. Los resultados aquí reportados se basan en una encuesta efectuada a 35 JV internacionales y ofrece resultados alineados con la literatura existente. Los resultados muestran que el desempeño organizacional mejora cuando se reduce la incertidumbre de factores percibidos como controlables por los directivos; un factor se percibe como controlable cuando mayor es la experiencia que el directivo tiene con el mismo. La incertidumbre, según la define Galbraith (1973), se reduce vía un uso intensivo de los sistemas de contabilidad de gestión, lo que su vez impacta positivamente en el desempeño organizacional.

Tarpon atlanticus in Colombia: a big fish in trouble

The natural history of Tarpon atlanticus (Valenciennes 1846) is reconstructed based on published information. Tarpon is a remarkable fish because of its peculiar larvae, large adult size, migration patterns and its capability to breathe atmospheric air. Destructive fisheries - some using dynamite - have much reduced the population of tarpon along the Caribbean coast of Colombia, and some catch data are presented which document this.

Diet composition of fish species from the southern continental shelf of Colombia

The diet composition of 30 fish species belonging to 16 families from the Pacific Coast of Colombia is described. Benthic crustaceans (37.5%) and bony fishes (23.7%, chiefly demersal) were the most important food items for the fish species analyzed. Data on diet composition of the fish species are presented for the first time which can be a source of information for trophic modeling.

History of the Atlantic Pearl-Oyster, Pinctata imbricata, Industry in Venezuela and Colombia, with Biological and Ecological Observations

In the 1500’s, the waters of Venezuela and to a lesser extent Colombia produced more natural pearls than any place ever produced in the world in any succeeding century. Atlantic pearl-oysters, Pinctata imbricata Röding 1798, were harvested almost entirely by divers. The pearls from them were exported to Spain and other European countries. By the end of the 1500’s, the pearl oysters had become much scarcer, and little harvesting took place during the 1600’s and 1700’s. Harvesting began to accelerate slowly in the mid 1800’s and has since continued but at a much lower rate than in the 1500’s. The harvesting methods have been hand collecting by divers until the early 1960’s, dredging from the 1500’s to the present, and hardhat diving from 1912 to the early 1960’s. Since the mid 1900’s, Japan and other countries of the western Pacific rim have inundated world markets with cultured pearls that are of better quality and are cheaper than natural pearls, and the marketing of natural pearls has nearly ended. The pearl oyster fishery in Colombia ended in the 1940’s, but it has continued in Venezuela with the fishermen selling the meats to support themselves; previously most meats had been discarded. A small quantity of pearls is now taken, and the fishery, which comprised about 3,000 fishermen in 1947, comprised about 300 in 2002.
