Marine Ornamental Shrimp

Biology, Aquaculture and Conservation

• Gebundenes Buch

Produktbeschreibung

Marine ornamental shrimp are amongst the most heavily traded invertebrate species in the aquarium industry. The majority of traded species are still collected from the wild, having a major effect on ocean ecosystems. An increase in the amount of culture of these species is now a major priority for those in the trade and for marine conservationists.

Inhaltsangabe

Chapter 1. Introduction (what is a marine ornamental shrimp?). This first
chapter will provide an overview on marine ornamental shrimp, namely the
features displayed by the species that made them suitable for the marine
aquarium trade. This chapter can help recruiting new species to the trade,
and will emphasize the importance of addressing in the advance the culture
potential of such species. Chapter 2. Collected and traded species. This
chapter presents a list of marine ornamental shrimp species commonly
available in the trade, their distribution area and particular features
that make them so prized in the marine aquarium industry. Chapter 3.
Ecological remarks. The relevant aspects of the ecology of the most heavily
collected and/or popular shrimp species will be described, namely their
habitat, symbiotic relations and fish cleaning behavior. . Chapter 4.
Reproductive biology and mating behavior. This chapter will focus the
sexual systems of marine ornamental shrimp species, sexual dimorphism and
mating, with emphasis on the agonistic behaviors of some species towards
conspecifics. Chapter 5. Larval development. The most distinct larval
features of marine ornamental shrimp will be described in this chapter,
highlighting the potential displayed by some species to delay metamorphosis
when facing unfavorable conditions. The role of settlement cues to trigger
metamorphosis and larval adaptations to avoid predation will also be
addressed. Chapter 6. Broodstock maintenance in captivity. This chapter
addresses how gonad maturation and embryo production can be induced in
breeding pairs of marine ornamental shrimp kept in captivity. Maturation
systems, diets and offspring quality will be the main topics, with
currently available protocols on these issues being addressed in detail.
Chapter 7. Larval culture. Currently considered the bottleneck still
impairing commercial scale production of some species, several aspects
related to larval culture will be discussed in this chapter. The main
topics will be the suitability of larval rearing systems, live and inert
larval diets, stocking densities, early and late larval stage mortality and
ability to delay metamorphosis. Chapter 8. Juvenile culture. This chapter
will discuss the protocols currently established to raise juvenile marine
ornamental shrimp. Grow-out systems, dietary needs and stocking procedures
will be analyzed in detail. Chapter 9. Other marine ornamental decapod
species with culture potential. The culture potential and profitability of
marine ornamental hermit crabs, true crabs and lobsters will be focused in
this chapter. Culture protocols currently available for these organisms
will be discussed. Chapter 10. Future improvements on marine ornamental
shrimp culture. This chapter will discuss the future directions for marine
ornamental shrimp culture, namely how can current bottlenecks be solved.
The highlights of this chapter will be which new approaches are being
tested, namely the use of alternative live and inert larval diets,
mesocosms culture, and the potential use of late larval stages collected
from the wild and raised in captivity to marketable size. Chapter 11.
Conservation issues. The direct and indirect negative impacts that can be
associated to the collection of marine ornamental shrimp from their
habitat, namely coral reefs, are discussed in this chapter. Mitigation
measures are discussed and the role that cultured specimens can have in
reducing the pressure in wild populations is highlighted. Chapter 12.
Conclusions. The highlights of each chapter will be summarized in this
final chapter and some important guidelines for further studies on marine
ornamental shrimp will be addressed, namely the need to perform further
ecological studies on the most heavily collected species, to ascertain the
real impacts of ornamental shrimp harvest and the diffusion of established
culture protocols to increase the offer of cultured specimens in the
aquarium trade.
