Controlled production of Artemia biomass using an inert commercial diet, compared with the microalgae Chaetoceros
TLDR
The results show that rearing Artemia with Nestum is a viable and economical alternative to the laborious production of unicellular algae. Expand
Combined production of fish and plants in recirculating water
TLDR
Determination of the physical and chemical parameters for optimum water purification, the most suitable ratio of denitrification by plants and by microorganisms, and the most favourable fish and plant species for combined culture in recirculating water are important in view of the increasing demand for clean, fresh water. Expand
Ecological observations and biomass proximate composition of the brine shrimp Artemia (Crustacea: Anostraca) from Pichilingue, Baja California Sur, México
TLDR
The proximate analysis of Artemia biomass showed only small differences, with the exception of the crude fibre content, and the biomass production and the size, especially of the females, decreased drastically, probably due to limited availability of natural food and to environmental stress. Expand
Analysis of Indigo-type compounds in natural dyes by negative ion atmospheric pressure photoionization mass spectrometry
Atmospheric Pressure Photoionization (APPI) in Mass Spectrometry (MS) has been utilized for a lumber of indigo-related compounds and was found to exhibit an excellent response. All structures wereExpand
A review of public health problems associated with the integration of animal husbandry and aquaculture, with emphasis on southeast Asia
Abstract Although the recycling of excrements in integrated agriculture-aquaculture farming systems offers many advantages, the spread of diseases to man via aquatic organisms multiplying inExpand
THE HYPOBRANCHIAL GLAND FROM THE PURPLE SNAIL PLICOPURPURA PANSA (GOULD, 1853) (PROSOBRANCHIA: MURICIDAE)
Abstract Results are presented on the histology of the hypobranchial gland of the marine muricid Plicopurpura pansa (Gould 1853). The general structure and secretory features were investigated usingExpand

The integration of aquaculture into agricultural production systems to intensify profitable food production without the usual environmental degradation appears to be a promising option for a largeExpand
THE EFFECT OF PERIODICALLY “MILKING” TO OBTAIN TYRIAN PURPLE FROM PLICOPURPURA PANSA (GOULD, 1853) ON THE FREQUENCY OF EXPULSION AND MORTALITY
TLDR
From the results reported here the decline of natural snail populations after milking could be explained by the environmental conditions of the intertidal zone. Expand
