Diversity of Brachyuran crabs in Gulf of Mannar (Southeast coast of India)
Coral reefs protect the coastline against waves and erosion and constitute one of the most diverse marine ecosystems in the World. Coral reefs provide Subsistence, security and cultural utility to the inhabitants of coastal areas in all the tropical nations. Nevertheless, reef degradation is
Widespread, due to their manifold uses and importance to the people or developing countries. Therefore the lnternational Union for Conservation of
Nature and Natural resources (IUCN) considers maintenance of reef fisheries as a global priority. Collection of data about the coral reef resources is the most basic information in a coral reef ecological study. Management could be done only on the basis of such informatio
Nutritional value of Pleurotus (Flabellatus) Djamor (R-22) cultivated on sawdusts of different woods
The sawdust of different woods were investigat
ed for the cultivation of exotic strain of
Pleurotus (flabellatus) djamor
(R-22)
to find out the efficiency of different nutrients including protein, fat, crude fiber, ash, dry matter and moisture.
Among all type of nutrients, protein, fat, cr
ude fiber, ash, dry matter and moisture of
Pleurotus ostreatus
on sawdust of
different woods were observed. Protein was observed on cont
rol treatment (cotton waste, kikar, mango, mixed sawdust,
simbal and kail (21.89), (21.64), (21.34), (21.16), (21.03) and
(20.75) % respectively. Fat was observed on control treatment
(cotton waste, kikar, mango, mi
xed sawdust, simbal and kail (0.80), (0.53), (0
.41), (0.33), (0.24) and (0.11)% respectively.
Crude fiber was observed on control treatment (cotton waste, kikar, mango, mixed sawdust, simbal and kail (8.92), (8.45),
(8.17), (7.96), (7.70) and (7.32) % respectively. Ash was observ
ed on control treatment (cotton waste, kikar, mango, mixed
sawdust, simbal and kail (7.65), (6.75), (6
.47), (6.39), (6.33) and (6.23%) respectively. Dry matter was observed on control
treatment (cotton waste, kikar, mango, mixed sawdust, simbal and kail (6.47), (6.27), (6.13), (6.01), (5.87) and (5.67) %
respectively. Moisture was observed on control treatment (c
otton waste, kikar, mango, mixed sawdust, simbal and kail
(84.55), (81.20), (79.85), (76.26), (74.35) and (71.14) % respectively. Oyster mushroom showed relatively more contents on
control treatment cotton waste as compared to other substrates. The maximum protein, fat, crude fiber, ash, dry matter and
moisture contents in
Pleurotus (flabellatus) djamor (R-22)
was obtained on Kikar sawdust .The lowest contents was
obtained on kail sawdust
Influence of lunar phases on fish landings by gillnetters and trawlers
Observations made on new moon, full moon and during both quarters revealed variations in total catch as well as individual
species catch in gillnetters and trawlers. Gillnet catches of sardines and mackerels showed a gradual increasing trend from
new moon to full moon and then a decline towards the new moon whereas, barracuda and tuna catches exhibited an
increasing trend from full moon to new moon. The catches of seerfish and sailfish were high during full moon to new moon
quarter and were nominal during full moon. In trawl catches, during the first half of new moon and full moon days,
Fenneropenaeus indicus and Penaeus semisulcatus were caught in large numbers and Fenneropenaeus merguiensis dominated
the later half. Metapenaeus monoceros and Penaeus monodon were caught in lesser quantitie
Coral : "The excellent bone graft material"
Man's first use of corals can be traced back almost to 25,000 years as evidenced through small beads of perforated red corals recovered from the burial sites in Europe. These were perhaps used as ornaments and possibility traded by early man
Present status of coral reefs in Gulf of Mannar Islands
Coral reefs are the most diverse marine
ecosystems in the world. Typically they
contain number of specialised species
representing almost all groups of marine
animals. One of the reasons for the great
diversity of life in coral reef is the diversified
habitats they offer. The great number of
holes and crevices in the reef provides
abundant shelter for fishes and
invertebrates. Coral reefs are also important
nurseries and are thus a peculiar store
house and repository of various animals
Brachyuran crabs of Gulf of Mannar
Coral reef ecosystems are tropical, shallow water marine ecosystems, largely restricted to ttJe area between the latitudes 300N and 300S of equator. Even though, they occupy less than 0.2 % of the ocean floor, they contain perhaps 25% of the ocean's species (IUCN/UNEP, 1985). Thus the coral reef ecosystems are well known for their species richness and also complexity.
It is quite remarkable that an environment with so small an area, has so much life and so many species and thus diversity. Typically they contain number of specialised species representing almost all the groups of marine animals
Vision Encoder-Decoder Models for AI Coaching
This research paper introduces an innovative AI coaching approach by
integrating vision-encoder-decoder models. The feasibility of this method is
demonstrated using a Vision Transformer as the encoder and GPT-2 as the
decoder, achieving a seamless integration of visual input and textual
interaction. Departing from conventional practices of employing distinct models
for image recognition and text-based coaching, our integrated architecture
directly processes input images, enabling natural question-and-answer dialogues
with the AI coach. This unique strategy simplifies model architecture while
enhancing the overall user experience in human-AI interactions. We showcase
sample results to demonstrate the capability of the model. The results
underscore the methodology's potential as a promising paradigm for creating
efficient AI coach models in various domains involving visual inputs.
Importantly, this potential holds true regardless of the particular visual
encoder or text decoder chosen. Additionally, we conducted experiments with
different sizes of GPT-2 to assess the impact on AI coach performance,
providing valuable insights into the scalability and versatility of our
proposed methodology.Comment: 6 pages, 2 figure
Complete larval development of the hermit crabs Clibanarius aequabilis and Clibanarius erythropus (Decapoda : Anomura : Diogenidae), under laboratory conditions, with a revision of the larval features of genus Clibanarius
The complete larval development (four zoeae and one megalopa) of Clibanarius aequabilis and C. erythropus, reared under laboratory conditions, is described and illustrated. The larval stages of the two northeastern Atlantic Clibanarius species cannot be easily differentiated. Their morphological characters are compared with those of other known Clibanarius larvae. The genus Clibanarius is very homogeneous with respect to larval characters. All Clibanarius zoeae display a broad and blunt rostrum, smooth abdominal segments and an antennal scale without a terminal spine. Beyond the second zoeal stage, the fourth telson process is present as a fused spine, and the uropods are biramous. In the fourth larval stage all species display a mandibular palp. The Clibanarius megalopa presents weakly developed or no ocular scales, symmetrical chelipeds, apically curved corneous dactylus in the second and third pereiopods, and 5-11 setae on the posterior margin of the telson. Apart from the number of zoeal stages, Clibanarius species may be separated, beyond the second zoeal stage, by the telson formula and the morphology of the fourth telson process.info:eu-repo/semantics/publishedVersio
Relative growth of harpiosquilla raphidea (Fabricius, 1798) (Crustacea: Stomatopoda) male and female populations
Morphometric analysis was carried out to find out changes in the growth pattern of male and female stomatopod, Harpiosquilla raphidea. Six morphometric relationships were examined on 105 males and 105 females, ranging in size from 103 to 207 mm and from 104 to 222 mm in total length, respectively. In both the sexes, the relative growth of carapace length, propodus length of raptorial claw and total weight in relation to total length was found positively allometric. Telson width in both the sexes and abdomen width in males showed slightly negative allometry, while the abdomen width of females showed slightly positive allometry, indicating some variation in the growth between sexes which could be attributed to the energy requirement for maturation in females. The propodus of females was also found to be bigger than that of males. It is quite interesting as males only have larger chela in other crustaceans. It has a functional significance in that it is of immense help at the time of intense feeding during maturation of oocytes which requires higher energy
