more susceptible to diseases outbreaks and environmental changes. The quality of
wild Gracilaria/Gracilariopsis in recent years has been diminished due to declines
in the cultivation environments and increase in diseases (Alamsjah 2010). Using
asexually derived branches may lead to a reduction in genetic variability but more
work needs to be done on the population genetics of these taxa.
Fish Feed from Mangrove Associate Flora
Mangrove associate floral species are also used for preparing fish feed. Feed prepared from P. coarctata and Enteromorpha intestinalis have been found to boost up
the growth Macrobrachium rosenbergii. Such fish feed not only increase the growth
of the cultured species, but it also upgrades the water quality in terms of dissolved
oxygen and organic load (Mondal et al. 2014a, b). For producing cost effective feed
and maintaining an ecologically sound culture system environment, now-a-days,
artificial feeds prepared from seaweed are extensively used to grow shrimps and
prawns. In Indian Sundarbans, the growth, survival, protein percentage and histological sections of cultured prawn species were observed after feeding the culture
species with Enteromorpha based fish feed. This experiment generated few interesting results in terms of protein percentage, growth and survival value, which were
relatively higher in the cultured prawns (Macrobrachium rosenbergii) feed with
Enteromorpha based feed. The muscle configuration was also significantly different
from that of the control (Fig. 9.16).
Preparation of Snacks and Breakfast Items from Coastal
Floral Species
Human population needs a wide range of nutrients to perform various like processes
and lead a normal healthy life. A balanced diet (for human beings) refers to optimum levels of protein, carbohydrate, fat, fibre and different minerals. Salicornia is
a common halophyte growing in the mid-littoral and supra-littoral zones of the sea
coast and river mouth. This fleshy plant is found at the edges of wetlands, marshes,
sea shores and mudflats, actually on most alkaline flats (Smillie 2015). It is commonly known as pickle-weed, glasswort, sea beans, sea asparagus and crow’s foot
greens belonging to Amranthaceae family (Singh et al. 2014).
This plant has spongy stems with diminutive scale-like leaves, inconspicuous
flowers and fruits. The green plant turns orange, pink to reddish in autumn, before
dying in winter. The species is widely available in the intertidal mudflats of mangrove dominated Indian Sundarbans (Fig. 9.17).
Salicornia has been used since long back for edible purposes. The species is a
unique source of salt. The aerial parts of the plants are consumed in salads or processed into pickles, beverages etc. For its saltiness and crunchiness, it is used as a
